I reference to a few parts of the First book of Enoch Book of the Watchers in the first several Timeline chapters of this book. This chapter explains why.

There are 3 books of Enoch. The book of First Enoch is estimated to have on average to have been written between 250 BC and 50 AD. It is the First book of Enoch, which contains a verse that is quoted in Jude, in the Bible, and thus is of interest to us. The book of Second Enoch is estimated to have been written in the late first century AD, and the Third book of Enoch is estimated to have been written in the 5th or 6th century AD. There is no reason to think either the Second or Third book of Enoch might be quoted in inspired scripture, and so we aren't going to be studying them here.

The First Book of Enoch is divided into 5 sections, each of which were written at a different time. They are: The Book of Watchers (chapters 1-36) dated 3rd or early 2nd century BC, The Book of Parables (chapters 37-71) dated late 1st century BC, The Astronomical book (chapters 72-82) dated 3rd century BC, The Book of Dream Visions (chapters 83-90) dated 165-160 BC, The Epistle of Enoch (chapters 91-108) dated early 2nd century BC.

And since these were separate sections, written at separate times, by likely different authors, we are at first are going to focus on the first 36 chapters of First Enoch, which compose the Book of Watchers. This is where the quote in Jude is found. I will refer to this section as First Enoch BW, please understand I am just referring to the Book of the Watchers.

2 Tim 3:14-17 You, however, continue in the things you have learned and become convinced of, knowing from whom you have learned them, and that from childhood you have known the sacred writings which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus. All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work.

With what we can glean from Peter and Jude's letters, and Jude quoting First Enoch, I think it is clear that some of what is taught in First Enoch BW was considered reliable and true by the disciples of Jesus and early church. This would mainly have to do with the Nephilim, the dead of whom are demons, their fallen angel fathers, and the imprisonment of those fallen angels in the Abyss. The applicable verses are:

2 Pet 2:4 “For if God did not spare angels when they sinned, but cast them into Tartarus and committed them to pits of darkness, reserved for judgment”

Jude 1:6 “And angels who did not keep their own domain, but abandoned their proper abode, He has kept in eternal bonds under darkness for the judgment of the great day.”

Which line up with:

1 Enoch 10:11-15 And the Lord said unto Michael: Go, bind Semjaza and his associates who have united themselves with women so as to have defiled themselves with them in all their uncleanness. And when their sons have slain one another, and they have seen the destruction of their beloved ones, bind them fast for seventy generations in the valleys of the earth, till the day of their judgment and of their consummation, till the judgment that is for ever and ever is consummated. In those days they shall be led off to the abyss of fire: and to the torment and the prison in which they shall be confined for ever. And whosoever shall be condemned and destroyed will from thenceforth be bound together with them to the end of all generations.

Jude also directly quotes from the First Enoch Book of the Watchers:

Jude 1:14-15 And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints, To execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard [speeches] which ungodly sinners have spoken against him.

Which matches
1 Enoch 1:9 And behold! He cometh with ten thousands of His holy ones, To execute judgment upon all, And to destroy all the ungodly: And to convict all flesh of all the works of their ungodliness which they have ungodly committed, And of all the hard things which ungodly sinners have spoken against Him.

Enoch lived 7 generations after Adam, and First Enoch BW was written in the time between Malachi and Matthew, estimated somewhere from about 2nd to 3rd century BC. Some questions arise. How could First Enoch BW authentic if it claims to be written by Enoch, yet the date it was written would show that to be impossible? Jude is the one who declares that it is Enoch, 7th from Adam, himself, who prophesied what Jude quotes from First Enoch.

The real issue here is not whether First Enoch BW was considered canon at some time in the past (which it was in the early Ethiopic Christian church), but the question is how the Christian church should view the book today? Should we accept First Enoch BW as canon in the present? As inspired? As historically reliable? As useful, or not? What do we do with it now?

Also, how can Jude be considered reliable when he quotes from First Enoch BW, saying Enoch wrote it, if Enoch did not in fact write First Enoch BW? If Jude is scripture inspired by God, then Jude could not make the mistake of saying First Enoch BW was written by Enoch if it in fact was not. But Jude has been accepted as Holy Scripture for a long time, and must not be discarded. It can't be. So what is the solution then?

There is actually a Biblically sound and possible solution for how First Enoch BW could have been written when it was written, and still have been words from Enoch himself.

We read in the gospels, of John the Baptist,
"And if you are willing to accept {it,} John himself is Elijah who was to come." Matt 11:14)
Also in Mal 4:5-6 we read, "Behold, I am going to send you Elijah the prophet before the coming of the great and terrible day of the LORD. And he will restore the hearts of the fathers to their children, and the hearts of the children to their fathers, lest I come and smite the land with a curse." In Luke 1:11-17 we read:

It is very interesting that John the Baptist was filled with the Holy Spirit while still in his mother's womb. John the Baptist was somehow "in the spirit and power": the prophet Elijah. Elijah is one of only two men mentioned in the Bible to have not died. We read in the Bible that each man is given one time to die, and then the judgment. Elijah was taken to God without dying, and there we see in some way that John the Baptist was Elijah come again. Therefore, We know Elijah was John the Baptist because Jesus tells us this. Please note, I am not saying reincarnation for any people or person is possible or true as some Eastern religions claim. I do not understand how this worked, that John the Baptist was Elijah, but Jesus said he was, so we know it is true that somehow he was. This was a special situation and circumstance. I do not know exactly what this means, but the only other person in the Bible to not have died, and thus able to be another possible candidate for whatever This was, is Enoch. Both Elijah and Enoch did not die, because God took them up into the sky, still alive.

Therefore, I propose that Enoch also was somehow another person of a new name, 'in the spirit and power of Enoch',  who lived from the time between the 2nd and 3rd century BC, in the same way that Elijah was also John the Baptist. God inspired this person, who in this indescribable way was Enoch, to write the line of scripture quoted by Jude out of First Enoch BW. Perhaps this person recorded down what Enoch actually said and did back in the time before the Flood of Noah's days. This person was Enoch in the same way that John the Baptist was Elijah (however it worked and I don’t claim to understand how it worked- just that Jesus Himself said it was true that John the Baptist was Elijah. And if you are willing to accept {it,} John himself is Elijah who was to come." (Matt 11:14) )

In this, the Holy inspiration of the book of Jude is no longer in question, as well as Peter and Jude's references and beliefs based on information in First Enoch are shown to be valid. In a way, Enoch himself actually did give the words of (at least some of) First Enoch BW. In this there is no conflict. This is a possibility, however it is not provable. But what is absolutely certain is that some parts of First Enoch directly correspond to what both Jude and Peter taught, and things that Jesus seemed aware of, things demons referenced to, and also 1 verse in First Enoch BW is directly quoted by Jude.

If nothing else First Enoch BW seems to clearly contain information that the apostles considered reliable, and as such I think some parts should be taken as historically reliable, if nothing else.

The question that next must be answered is if First Enoch the Book of the Watchers is reliable to any extent, then how much of it, and which parts of it? I've read First Enoch BW, and erring on the side of caution, analyzed it.

So let's take it a piece at a time:

[Chapter 1]

1 The words of the blessing of Enoch, wherewith he blessed the elect and righteous, who will be 2 living in the day of tribulation, when all the wicked and godless are to be removed. And he took up his parable and said -Enoch a righteous man, whose eyes were opened by God, saw the vision of the Holy One in the heavens, which the angels showed me, and from them I heard everything, and from them I understood as I saw, but not for this generation, but for a remote one which is 3 for to come. Concerning the elect I said, and took up my parable concerning them:

The Holy Great One will come forth from His dwelling, 4 And the eternal God will tread upon the earth, (even) on Mount Sinai, [And appear from His camp] And appear in the strength of His might from the heaven of heavens.5 And all shall be smitten with fear And the Watchers shall quake, And great fear and trembling shall seize them unto the ends of the earth.6 And the high mountains shall be shaken, And the high hills shall be made low, And shall melt like wax before the flame7 And the earth shall be wholly rent in sunder, And all that is upon the earth shall perish, And there shall be a judgment upon all (men). 8 But with the righteous He will make peace. And will protect the elect, And mercy shall be upon them. And they shall all belong to God, And they shall be prospered, And they shall all be blessed. And He will help them all, And light shall appear unto them, And He will make peace with them'. 9 And behold! He cometh with ten thousands of His holy ones To execute judgment upon all, And to destroy all the ungodly: And to convict all flesh Of all the works of their ungodliness which they have ungodly committed, And of all the hard things which ungodly sinners have spoken against Him.

{These underlined verses are directly quoted in the book of Jude, Jude saying Enoch prophesied this himself. This first section of chapter one should all be taken as going together}

[Chapter 2]

1 Observe ye everything that takes place in the heaven, how they do not change their orbits, and the luminaries which are in the heaven, how they all rise and set in order each in its season, and 2 transgress not against their appointed order. Behold ye the earth, and give heed to the things which take place upon it from first to last, how steadfast they are, how none of the things upon earth 3 change, but all the works of God appear to you. Behold the summer and the winter, how the whole earth is filled with water, and clouds and dew and rain lie upon it.

[Chapter 3]

Observe and see how (in the winter) all the trees seem as though they had withered and shed all their leaves, except fourteen trees, which do not lose their foliage but retain the old foliage from two to three years till the new comes.

[Chapter 4]

And again, observe ye the days of summer how the sun is above the earth over against it. And you seek shade and shelter by reason of the heat of the sun, and the earth also burns with growing heat, and so you cannot tread on the earth, or on a rock by reason of its heat.

[Chapter 5]

1 Observe ye how the trees cover themselves with green leaves and bear fruit: wherefore give ye heed and know with regard to all His works, and recognize how He that liveth for ever hath made them so. 2 And all His works go on thus from year to year for ever, and all the tasks which they accomplish for Him, and their tasks change not, but according as God hath ordained so is it done. 3 And behold how the sea and the rivers in like manner accomplish and change not their tasks from His commandments'.4 But ye -ye have not been steadfast, nor done the commandments of the Lord, But ye have turned away and spoken proud and hard words With your impure mouths against His greatness. Oh, ye hard-hearted, ye shall find no peace. 5 Therefore shall ye execrate your days, And the years of your life shall perish, And the years of your destruction shall be multiplied in eternal execration, And ye shall find no mercy. 6a In those days ye shall make your names an eternal execration unto all the righteous, b And by you shall all who curse, curse, And all the sinners and godless shall imprecate by you, 7c And for you the godless there shall be a curse. 6d And all the . . . shall rejoice, e And there shall be forgiveness of sins, f And every mercy and peace and forbearance: g There shall be salvation unto them, a goodly light. I And for all of you sinners there shall be no salvation, j But on you all shall abide a curse. 7a But for the elect there shall be light and joy and peace, b And they shall inherit the earth. 8 And then there shall be bestowed upon the elect wisdom, And they shall all live and never again sin, Either through ungodliness or through pride: But they who are wise shall be humble. 9 And they shall not again transgress, Nor shall they sin all the days of their life, Nor shall they die of (the divine) anger or wrath, But they shall complete the number of the days of their life. And their lives shall be increased in peace, And the years of their joy shall be multiplied, In eternal gladness and peace, All the days of their life.

I think that chapters 2-5 should also be taken as reliable. They are in fact a continuation of chapter one. The term "elect" is used repeatedly throughout chapters 1-5, and the prophecy has a flow that runs together. Chapter 2 through the beginning of chapter 5 talks a lot about God's command over nature, which seems a break in the flow, but it all ties back in at the end of chapter 5 to match up with the sound of chapter 1. So I think Chapters 1-5 should all be taken as one section of First Enoch BW, and as historically reliable.

Martin McNamara M.S.C., Biblical Scholar, writes of the Book of the Watchers: "This section of 1 Enoch is itself a composite work. It begins with a Parable of Enoch on the lot of the wicked and of the righteous (1-5). Next comes The Book of the Watchers (i.e. the Angels) proper. This recounts the sin of the angels through their sexual union with earthly women, on which follows the demoralization of humankind. We are then told of the doom pronounced by God on the angels and of the joys in store for the just (6-11)..."(Intertestamental Literature, p. 55)

James VanderKam, Professor of Hebrew Scriptures at the University of Notre Dame, write on First Enoch:

We could stop here, after section 1-5 which Jude quotes from, but there is information about the fallen angels imprisoned in the Abyss that is given by Peter and Jude, which comes up in the very next section of First Enoch BW. Because Peter and Jude's understanding is in the Holy Bible, and thus basis for church doctrine, there is a major problem that the information they had is nowhere in the Old Testament, and cannot be drawn from the Old Testament. Gen 6 does not give details about the imprisonment of the fallen angels in the Abyss, but Jude and Peter accepted such as truth. There should be some written information that Peter and Jude accepted as solid teaching about the fallen angels and the Abyss, but this is missing from the Bible today. And that information is found in the very next section in First Enoch BW. Here it is:

[Chapter 6]

1 And it came to pass when the children of men had multiplied that in those days were born unto 2 them beautiful and comely daughters. And the angels, the children of the heaven, saw and lusted after them, and said to one another: 'Come, let us choose us wives from among the children of men 3 and beget us children.' And Semjaza, who was their leader, said unto them: 'I fear ye will not 4 indeed agree to do this deed, and I alone shall have to pay the penalty of a great sin.' And they all answered him and said: 'Let us all swear an oath, and all bind ourselves by mutual imprecations 5 not to abandon this plan but to do this thing.' Then sware they all together and bound themselves 6 by mutual imprecations upon it. And they were in all two hundred; who descended in the days of Jared on the summit of Mount Hermon, and they called it Mount Hermon, because they had sworn 7 and bound themselves by mutual imprecations upon it. And these are the names of their leaders: Samlazaz, their leader, Araklba, Rameel, Kokablel, Tamlel, Ramlel, Danel, Ezeqeel, Baraqijal, 8 Asael, Armaros, Batarel, Ananel, Zaq1el, Samsapeel, Satarel, Turel, Jomjael, Sariel. These are their chiefs of tens.

[Chapter 7]

1 And all the others together with them took unto themselves wives, and each chose for himself one, and they began to go in unto them and to defile themselves with them, and they taught them charms 2 and enchantments, and the cutting of roots, and made them acquainted with plants. And they 3 became pregnant, and they bare great giants, whose height was three thousand ells: Who consumed 4 all the acquisitions of men. And when men could no longer sustain them, the giants turned against 5 them and devoured mankind. And they began to sin against birds, and beasts, and reptiles, and 6 fish, and to devour one another's flesh, and drink the blood. Then the earth laid accusation against the lawless ones.

[Chapter 8]

1 And Azazel taught men to make swords, and knives, and shields, and breastplates, and made known to them the metals of the earth and the art of working them, and bracelets, and ornaments, and the use of antimony, and the beautifying of the eyelids, and all kinds of costly stones, and all 2 colouring tinctures. And there arose much godlessness, and they committed fornication, and they 3 were led astray, and became corrupt in all their ways. Semjaza taught enchantments, and root-cuttings, 'Armaros the resolving of enchantments, Baraqijal (taught) astrology, Kokabel the constellations, Ezeqeel the knowledge of the clouds, Araqiel the signs of the earth, Shamsiel the signs of the sun, and Sariel the course of the moon. And as men perished, they cried, and their cry went up to heaven . . .

[Chapter 9]

1 And then Michael, Uriel, Raphael, and Gabriel looked down from heaven and saw much blood being 2 shed upon the earth, and all lawlessness being wrought upon the earth. And they said one to another: 'The earth made without inhabitant cries the voice of their cryingst up to the gates of heaven. 3 And now to you, the holy ones of heaven, the souls of men make their suit, saying, "Bring our cause 4 before the Most High."' And they said to the Lord of the ages: 'Lord of lords, God of gods, King of kings, and God of the ages, the throne of Thy glory (standeth) unto all the generations of the 5 ages, and Thy name holy and glorious and blessed unto all the ages! Thou hast made all things, and power over all things hast Thou: and all things are naked and open in Thy sight, and Thou seest all 6 things, and nothing can hide itself from Thee. Thou seest what Azazel hath done, who hath taught all unrighteousness on earth and revealed the eternal secrets which were (preserved) in heaven, which 7 men were striving to learn: And Semjaza, to whom Thou hast given authority to bear rule over his associates. And they have gone to the daughters of men upon the earth, and have slept with the 9 women, and have defiled themselves, and revealed to them all kinds of sins. And the women have 10 borne giants, and the whole earth has thereby been filled with blood and unrighteousness. And now, behold, the souls of those who have died are crying and making their suit to the gates of heaven, and their lamentations have ascended: and cannot cease because of the lawless deeds which are 11 wrought on the earth. And Thou knowest all things before they come to pass, and Thou seest these things and Thou dost suffer them, and Thou dost not say to us what we are to do to them in regard to these.'

[Chapter 10]

1 Then said the Most High, the Holy and Great One spake, and sent Uriel to the son of Lamech, 2 and said to him: 'Go to Noah and tell him in my name "Hide thyself!" and reveal to him the end that is approaching: that the whole earth will be destroyed, and a deluge is about to come 3 upon the whole earth, and will destroy all that is on it. And now instruct him that he may escape 4 and his seed may be preserved for all the generations of the world.' And again the Lord said to Raphael: 'Bind Azazel hand and foot, and cast him into the darkness: and make an opening 5 in the desert, which is in Dudael, and cast him therein. And place upon him rough and jagged rocks, and cover him with darkness, and let him abide there for ever, and cover his face that he may 6,7 not see light. And on the day of the great judgment he shall be cast into the fire. And heal the earth which the angels have corrupted, and proclaim the healing of the earth, that they may heal the plague, and that all the children of men may not perish through all the secret things that the 8 Watchers have disclosed and have taught their sons. And the whole earth has been corrupted 9 through the works that were taught by Azazel: to him ascribe all sin.' And to Gabriel said the Lord: 'Proceed against the bastards and the reprobates, and against the children of fornication: and destroy [the children of fornication and] the children of the Watchers from amongst men [and cause them to go forth]: send them one against the other that they may destroy each other in 10 battle: for length of days shall they not have. And no request that they (i.e. their fathers) make of thee shall be granted unto their fathers on their behalf; for they hope to live an eternal life, and 11 that each one of them will live five hundred years.' And the Lord said unto Michael: 'Go, bind Semjaza and his associates who have united themselves with women so as to have defiled themselves 12 with them in all their uncleanness. And when their sons have slain one another, and they have seen the destruction of their beloved ones, bind them fast for seventy generations in the valleys of the earth, till the day of their judgment and of their consummation, till the judgment that is 13 for ever and ever is consummated. In those days they shall be led off to the abyss of fire: and 14 to the torment and the prison in which they shall be confined for ever. And whosoever shall be condemned and destroyed will from thenceforth be bound together with them to the end of all 15 generations. And destroy all the spirits of the reprobate and the children of the Watchers, because 16 they have wronged mankind. Destroy all wrong from the face of the earth and let every evil work come to an end: and let the plant of righteousness and truth appear: and it shall prove a blessing; the works of righteousness and truth' shall be planted in truth and joy for evermore.17 And then shall all the righteous escape, And shall live till they beget thousands of children, And all the days of their youth and their old age Shall they complete in peace.18 And then shall the whole earth be tilled in righteousness, and shall all be planted with trees and 19 be full of blessing. And all desirable trees shall be planted on it, and they shall plant vines on it: and the vine which they plant thereon shall yield wine in abundance, and as for all the seed which is sown thereon each measure (of it) shall bear a thousand, and each measure of olives shall yield 20 ten presses of oil. And cleanse thou the earth from all oppression, and from all unrighteousness, and from all sin, and from all godlessness: and all the uncleanness that is wrought upon the earth 21 destroy from off the earth. And all the children of men shall become righteous, and all nations 22 shall offer adoration and shall praise Me, and all shall worship Me. And the earth shall be cleansed from all defilement, and from all sin, and from all punishment, and from all torment, and I will never again send (them) upon it from generation to generation and for ever.

[Chapter 11]

1 And in those days I will open the store chambers of blessing which are in the heaven, so as to send 2 them down upon the earth over the work and labour of the children of men. And truth and peace shall be associated together throughout all the days of the world and throughout all the generations of men.'
 

In section 6-11 is found understanding of what Peter and Jude referenced to when they said:

2 Pet 2:4 “For if God did not spare angels when they sinned, but cast them into Tartarus and committed them to pits of darkness, reserved for judgment”

Jude 1:6 “And angels who did not keep their own domain, but abandoned their proper abode, He has kept in eternal bonds under darkness for the judgment of the great day.”

I see nothing in this section which conflicts with the Bible, but rather it seems to be a work which is referenced to in the Bible for information by Peter and Jude, as being at least historically reliable.

However, this section 6-11 does not explain why demons are fearful and dread the Abyss place, as seen in Luke 8:31,
"Jesus asked him, "What is your name?"  "Legion," he replied, because many demons had gone into him. And they begged him repeatedly not to order them to go into the Abyss."
An explanation for the familiarity of demons with the Abyss, and their dread of it, this is found in chapters 12-16.

[Chapter 12]

1 Before these things Enoch was hidden, and no one of the children of men knew where he was 2 hidden, and where he abode, and what had become of him. And his activities had to do with the Watchers, and his days were with the holy ones. 3 And I Enoch was blessing the Lord of majesty and the King of the ages, and lo! the Watchers 4 called me -Enoch the scribe- and said to me: 'Enoch, thou scribe of righteousness, go, declare to the Watchers of the heaven who have left the high heaven, the holy eternal place, and have defiled themselves with women, and have done as the children of earth do, and have taken unto themselves 5 wives: "Ye have wrought great destruction on the earth: And ye shall have no peace nor forgiveness 6 of sin: and inasmuch as they delight themselves in their children, The murder of their beloved ones shall they see, and over the destruction of their children shall they lament, and shall make supplication unto eternity, but mercy and peace shall ye not attain."'

[Chapter 13]

1 And Enoch went and said: 'Azazel, thou shalt have no peace: a severe sentence has gone forth 2 against thee to put thee in bonds: And thou shalt not have toleration nor request granted to thee, because of the unrighteousness which thou hast taught, and because of all the works of godlessness 3 and unrighteousness and sin which thou hast shown to men.' Then I went and spoke to them all 4 together, and they were all afraid, and fear and trembling seized them. And they besought me to draw up a petition for them that they might find forgiveness, and to read their petition in the presence 5 of the Lord of heaven. For from thenceforward they could not speak (with Him) nor lift up their 6 eyes to heaven for shame of their sins for which they had been condemned. Then I wrote out their petition, and the prayer in regard to their spirits and their deeds individually and in regard to their 7 requests that they should have forgiveness and length. And I went off and sat down at the waters of Dan, in the land of Dan, to the south of the west of Hermon: I read their petition till I fell 8 asleep. And behold a dream came to me, and visions fell down upon me, and I saw visions of chastisement, and a voice came bidding (me) I to tell it to the sons of heaven, and reprimand them. 9 And when I awaked, I came unto them, and they were all sitting gathered together, weeping in 10 'Abelsjail, which is between Lebanon and Seneser, with their faces covered. And I recounted before them all the visions which I had seen in sleep, and I began to speak the words of righteousness, and to reprimand the heavenly Watchers.

[Chapter 14]

1 The book of the words of righteousness, and of the reprimand of the eternal Watchers in accordance 2 with the command of the Holy Great One in that vision. I saw in my sleep what I will now say with a tongue of flesh and with the breath of my mouth: which the Great One has given to men to 3 converse therewith and understand with the heart. As He has created and given to man the power of understanding the word of wisdom, so hath He created me also and given me the power of reprimanding 4 the Watchers, the children of heaven. I wrote out your petition, and in my vision it appeared thus, that your petition will not be granted unto you throughout all the days of eternity, and that judgment 5 has been finally passed upon you: yea (your petition) will not be granted unto you. And from henceforth you shall not ascend into heaven unto all eternity, and in bonds of the earth the decree 6 has gone forth to bind you for all the days of the world. And (that) previously you shall have seen the destruction of your beloved sons and ye shall have no pleasure in them, but they shall fall before 7 you by the sword. And your petition on their behalf shall not be granted, nor yet on your own: even though you weep and pray and speak all the words contained in the writing which I have 8 written. And the vision was shown to me thus: Behold, in the vision clouds invited me and a mist summoned me, and the course of the stars and the lightnings sped and hastened me, and the winds in 9 the vision caused me to fly and lifted me upward, and bore me into heaven. And I went in till I drew nigh to a wall which is built of crystals and surrounded by tongues of fire: and it began to affright 10 me. And I went into the tongues of fire and drew nigh to a large house which was built of crystals: and the walls of the house were like a tesselated floor (made) of crystals, and its groundwork was 11 of crystal. Its ceiling was like the path of the stars and the lightnings, and between them were 12 fiery cherubim, and their heaven was (clear as) water. A flaming fire surrounded the walls, and its 13 portals blazed with fire. And I entered into that house, and it was hot as fire and cold as ice: there 14 were no delights of life therein: fear covered me, and trembling got hold upon me. And as I quaked 15 and trembled, I fell upon my face. And I beheld a vision, And lo! there was a second house, greater 16 than the former, and the entire portal stood open before me, and it was built of flames of fire. And in every respect it so excelled in splendour and magnificence and extent that I cannot describe to 17 you its splendour and its extent. And its floor was of fire, and above it were lightnings and the path 18 of the stars, and its ceiling also was flaming fire. And I looked and saw therein a lofty throne: its appearance was as crystal, and the wheels thereof as the shining sun, and there was the vision of 19 cherubim. And from underneath the throne came streams of flaming fire so that I could not look 20 thereon. And the Great Glory sat thereon, and His raiment shone more brightly than the sun and 21 was whiter than any snow. None of the angels could enter and could behold His face by reason 22 of the magnificence and glory and no flesh could behold Him. The flaming fire was round about Him, and a great fire stood before Him, and none around could draw nigh Him: ten thousand times 23 ten thousand (stood) before Him, yet He needed no counselor. And the most holy ones who were 24 nigh to Him did not leave by night nor depart from Him. And until then I had been prostrate on my face, trembling: and the Lord called me with His own mouth, and said to me: ' Come hither, 25 Enoch, and hear my word.' And one of the holy ones came to me and waked me, and He made me rise up and approach the door: and I bowed my face downwards.

[Chapter 15]

1 And He answered and said to me, and I heard His voice: 'Fear not, Enoch, thou righteous 2 man and scribe of righteousness: approach hither and hear my voice. And go, say to the Watchers of heaven, who have sent thee to intercede for them: "You should intercede" for men, and not men 3 for you: Wherefore have ye left the high, holy, and eternal heaven, and lain with women, and defiled yourselves with the daughters of men and taken to yourselves wives, and done like the children 4 of earth, and begotten giants (as your) sons? And though ye were holy, spiritual, living the eternal life, you have defiled yourselves with the blood of women, and have begotten (children) with the blood of flesh, and, as the children of men, have lusted after flesh and blood as those also do who die 5 and perish. Therefore have I given them wives also that they might impregnate them, and beget 6 children by them, that thus nothing might be wanting to them on earth. But you were formerly 7 spiritual, living the eternal life, and immortal for all generations of the world. And therefore I have not appointed wives for you; for as for the spiritual ones of the heaven, in heaven is their dwelling. 8 And now, the giants, who are produced from the spirits and flesh, shall be called evil spirits upon 9 the earth, and on the earth shall be their dwelling. Evil spirits have proceeded from their bodies; because they are born from men and from the holy Watchers is their beginning and primal origin; 10 they shall be evil spirits on earth, and evil spirits shall they be called. [As for the spirits of heaven, in heaven shall be their dwelling, but as for the spirits of the earth which were born upon the earth, on the earth shall be their dwelling.] And the spirits of the giants afflict, oppress, destroy, attack, do battle, and work destruction on the earth, and cause trouble: they take no food, but nevertheless 12 hunger and thirst, and cause offences. And these spirits shall rise up against the children of men and against the women, because they have proceeded from them.

[Chapter 16]

1 From the days of the slaughter and destruction and death of the giants, from the souls of whose flesh the spirits, having gone forth, shall destroy without incurring judgment -thus shall they destroy until the day of the consummation, the great judgment in which the age shall be 2 consummated, over the Watchers and the godless, yea, shall be wholly consummated." And now as to the watchers who have sent thee to intercede for them, who had been aforetime in heaven, (say 3 to them): "You have been in heaven, but all the mysteries had not yet been revealed to you, and you knew worthless ones, and these in the hardness of your hearts you have made known to the women, and through these mysteries women and men work much evil on earth." 4 Say to them therefore: " You have no peace."'

It is in section 12-16 that we can find the clarification that the Nephilim spirits, when their bodies dies, became evil spirits upon the earth, also known as demons. This would explain why the demons are afraid of being sent to the Abyss, a place rarely referenced in the Bible, for the demons remember a time when their fallen angel fathers were imprisoned in the Abyss.

Chapters 6-16 cover all the vital information about the fallen angels that we need in order to understand where Peter and Jude were getting their information, and this verse in Luke. I see nothing here that is in conflict with already accepted Holy Scriptures. I would accept chapters 6-16 as being historically reliable.

Moving on:

[Chapter 17]

1 And they took and brought me to a place in which those who were there were like flaming fire, 2 and, when they wished, they appeared as men. And they brought me to the place of darkness, and to a mountain the point of whose summit reached to heaven. And I saw the places of the luminaries and the treasuries of the stars and of the thunder and in the uttermost depths, where were 4 a fiery bow and arrows and their quiver, and a fiery sword and all the lightnings. And they took 5 me to the living waters, and to the fire of the west, which receives every setting of the sun. And I came to a river of fire in which the fire flows like water and discharges itself into the great sea towards 6 the west. I saw the great rivers and came to the great river and to the great darkness, and went 7 to the place where no flesh walks. I saw the mountains of the darkness of winter and the place 8 whence all the waters of the deep flow. I saw the mouths of all the rivers of the earth and the mouth of the deep.

[Chapter 18]

1 I saw the treasuries of all the winds: I saw how He had furnished with them the whole creation 2 and the firm foundations of the earth. And I saw the corner-stone of the earth: I saw the four 3 winds which bear [the earth and] the firmament of the heaven. And I saw how the winds stretch out the vaults of heaven, and have their station between heaven and earth: these are the pillars 4 of the heaven. I saw the winds of heaven which turn and bring the circumference of the sun and 5 all the stars to their setting. I saw the winds on the earth carrying the clouds: I saw the paths 6 of the angels. I saw at the end of the earth the firmament of the heaven above. And I proceeded and saw a place which burns day and night, where there are seven mountains of magnificent stones, 7 three towards the east, and three towards the south. And as for those towards the east, was of coloured stone, and one of pearl, and one of jacinth, and those towards the south of red stone. 8 But the middle one reached to heaven like the throne of God, of alabaster, and the summit of the 9,10 throne was of sapphire. And I saw a flaming fire. And beyond these mountains Is a region the end of the great earth: there the heavens were completed. And I saw a deep abyss, with columns of heavenly fire, and among them I saw columns of fire fall, which were beyond measure alike towards 12 the height and towards the depth. And beyond that abyss I saw a place which had no firmament of the heaven above, and no firmly founded earth beneath it: there was no water upon it, and no 13 birds, but it was a waste and horrible place. I saw there seven stars like great burning mountains, 14 and to me, when I inquired regarding them, The angel said: 'This place is the end of heaven and earth: this has become a prison for the stars and the host of heaven. And the stars which roll over the fire are they which have transgressed the commandment of the Lord in the beginning of 16 their rising, because they did not come forth at their appointed times. And He was wroth with them, and bound them till the time when their guilt should be consummated (even) for ten thousand years.'

[Chapter 19]

1 And Uriel said to me: 'Here shall stand the angels who have connected themselves with women, and their spirits assuming many different forms are defiling mankind and shall lead them astray into sacrificing to demons as gods, (here shall they stand,) till the day of the great judgment in 2 which they shall be judged till they are made an end of. And the women also of the angels who 3 went astray shall become sirens.' And I, Enoch, alone saw the vision, the ends of all things: and no man shall see as I have seen.
 

I consider chapters 17-19 to be questionable as to their reliability, because they seem to be a separate section from chapters 6-16. I also am not sure how essential the information therein would be to Peter and Jude's understanding, which their letters show they possessed. And we are getting further and further away from that which is confirmed by Holy Scripture (chapter 1 verse 9). Apparently my view on this coincides with James C. Vanderkam (Professor of Hebrew Scriptures at the University of Notre Dame), who also places 17-19 as a section, and chapters 20-36 as another final section.

However, some interesting things are brought out in chapters 17-19. One is that though chapter 10:12 says the fallen angels are to bound in the valleys of the earth, also called the Abyss or Tartarus, chapter 17 says they are bound at the end of heaven and earth. 2 Pet 2 says the fallen angels are bound in chains of darkness, and Jude says in darkness as well. But in 2nd Peter is a reference to the chains in specific. Yet 1 Enoch 18:10-14 describes this prison as containing heavenly fire, and the place sounds luminous, not deep darkness. There seems to be a conflict here between chapters 17-19 and Jude on the issue of darkness of the Abyss. As to the location of the Abyss, it must both be in the valleys of the earth, and at the end of heaven and earth, if 17-19 are reliable, and this seems to conflict. One possibility, as fallen angels are higher-dimensional beings as I describe in another chapter, is that the scene described in chapters 17-19 is on a higher-dimensional plane, yet the location of this higher-dimensional prison is still in the valleys of the earth. The term Abyss can refer to deep oceans, and tends to imply the location is below the earth, below the lowest depths of the sea, under the ground, in the earth. If the prison of the fallen angels is on a higher-dimensional plane, then it of course is not going to be found by 4 dimensional instrumentation or searching for it, but might have a general location in the world in the 4 dimensional sense. Yet, in plain wording and straight-forward understanding, there is a direct conflict between a luminous place and a place of darkness.

Another interesting thing is that the "women also of the angels who went astray shall become sirens". I am not sure what a siren technically is, but it may be a term referring to a female demon. If that is the case, then this fits in very well with ideas I will present later, that the fallen angels sired Nephilim, which sired daughters, and those daughters when they died became disembodied evil spirits, a.k.a. demons. If these verses are interpreted that way, then it makes sense. However if these verses are taken to mean that the human women who mated with the fallen angels became female demons, or really Anything different than just a normal dead person when they died, then these verses must be taken as unreliable, definitely conflicting scripture, because that isn’t true. Humans don’t become demons.

The next section I will include is chapters 20-22. I do not believe these are reliable whatsoever.

[Chapter 20] 1,2 And these are the names of the holy angels who watch. Uriel, one of the holy angels, who is 3 over the world and over Tartarus. Raphael, one of the holy angels, who is over the spirits of men. 4,5 Raguel, one of the holy angels who takes vengeance on the world of the luminaries. Michael, one 6 of the holy angels, to wit, he that is set over the best part of mankind and over chaos. Saraqael, 7 one of the holy angels, who is set over the spirits, who sin in the spirit. Gabriel, one of the holy 8 angels, who is over Paradise and the serpents and the Cherubim. Remiel, one of the holy angels, whom God set over those who rise.

In chapter 20 it starts with a list of the names of angels and what they are in charge of. Nowhere in Holy scripture do we see God tell us these things. The names of the angels are typically things that it seems God discourages us from learning about. That is because people have been too inclined to develop a worshipful fascination with angels. The information and style here is very different from anything in established scripture. The list of fallen angels earlier in Enoch is irrelevant when it comes to interaction with those fallen angels because they are now imprisoned in the Abyss. Some Holy Angels are mentioned earlier in First Enoch, but only in passing. Nowhere else is the main point of the passage that we learn the names of angels and what they do. Nowhere in the Bible is this kind of information or list found either. This chapter just strikes me as entirely uninspired scripture, and contradictory to the Bible in its type of content.

[Chapter 21] 1,2 And I proceeded to where things were chaotic. And I saw there something horrible: I saw neither 3 a heaven above nor a firmly founded earth, but a place chaotic and horrible. And there I saw 4 seven stars of the heaven bound together in it, like great mountains and burning with fire. Then 5 I said: 'For what sin are they bound, and on what account have they been cast in hither?' Then said Uriel, one of the holy angels, who was with me, and was chief over them, and said: 'Enoch, why 6 dost thou ask, and why art thou eager for the truth? These are of the number of the stars of heaven, which have transgressed the commandment of the Lord, and are bound here till ten thousand years, 7 the time entailed by their sins, are consummated.' And from thence I went to another place, which was still more horrible than the former, and I saw a horrible thing: a great fire there which burnt and blazed, and the place was cleft as far as the abyss, being full of great descending columns of 8 fire: neither its extent or magnitude could I see, nor could I conjecture. Then I said: 'How 9 fearful is the place and how terrible to look upon!' Then Uriel answered me, one of the holy angels who was with me, and said unto me: 'Enoch, why hast thou such fear and affright?' And 10 I answered: 'Because of this fearful place, and because of the spectacle of the pain.' And he said unto me: 'This place is the prison of the angels, and here they will be imprisoned for ever.'

Here we see the same scene repeated, redundantly, that was mentioned earlier in chapters 17-19. One of the key differences here is that here the angels are said to be imprisoned for a concrete "ten thousand years" which is a very defined period of time. In earlier, likely reliable portions, we are told they will be imprisoned for "even for ten thousand years" which is a loose term that implies a very long time, even up to or past ten thousand years. And we were also told they will be imprisoned "for seventy generations" which is another loose term, an unspecified long time. This is more the style of inspired scripture. We do not know exactly when Jesus will return, thus marking the beginning of His 1000 year reign on this Earth. And thus we don't know exactly when that will end and the day of judgment will come, following the end of Jesus' blessed 1000 year reign on Earth. And it is on the day of judgment that the fallen angels in the Abyss will stand judgment. So the Bible leaves the date unspecified of their release and judgment. As such, in keeping with scripture, potentially inspired portions of First Enoch would not give us a specific amount of time. There is a big difference between "even for ten thousand years" and "for ten thousand years"; the first is vague and the second is not. And so chapter 21 I would not consider reliable historically nor prophetically.

[Chapter 22] 1 And thence I went to another place, and he mountain [and] of hard rock. 2 And there was in it four hollow places, deep and wide and very smooth. How smooth are the hollow places and deep and dark to look at. 3 Then Raphael answered, one of the holy angels who was with me, and said unto me: 'These hollow places have been created for this very purpose, that the spirits of the souls of the dead should 4 assemble therein, yea that all the souls of the children of men should assemble here. And these places have been made to receive them till the day of their judgment and till their appointed period [till the period appointed], till the great judgment (comes) upon them.' I saw (the spirit of) a dead man making suit, 5 and his voice went forth to heaven and made suit. And I asked Raphael the angel who was 6 with me, and I said unto him: 'This spirit which maketh suit, whose is it, whose voice goeth forth and maketh suit to heaven ?' 7 And he answered me saying: 'This is the spirit which went forth from Abel, whom his brother Cain slew, and he makes his suit against him till his seed is destroyed from the face of the earth, and his seed is annihilated from amongst the seed of men.' 8 The I asked regarding it, and regarding all the hollow places: 'Why is one separated from the other?' 9 And he answered me and said unto me: 'These three have been made that the spirits of the dead might be separated. And such a division has been make (for) the spirits of the righteous, in which there is the bright spring of 10 water. And such has been made for sinners when they die and are buried in the earth and judgment has not been executed on them in their 11 lifetime. Here their spirits shall be set apart in this great pain till the great day of judgment and punishment and torment of those who curse for ever and retribution for their spirits. There 12 He shall bind them for ever. And such a division has been made for the spirits of those who make their suit, who make disclosures concerning their destruction, when they were slain in the days 13 of the sinners. Such has been made for the spirits of men who were not righteous but sinners, who were complete in transgression, and of the transgressors they shall be companions: but their spirits shall not be slain in the day of judgment nor shall they be raised from thence.' 14 The I blessed the Lord of glory and said: 'Blessed be my Lord, the Lord of righteousness, who ruleth for ever.'

In Chapter 22 there are several problems. First is the idea that Sheol has chambers. There is nothing else in the Bible, when it's understood as it was written, that supports this idea that Sheol (the grave) has chambers. The Grave is better understood as a state of being rather than a place, in my opinion. In any case, the only place in which any place of the dead is mentioned to have sections would be Hades, mentioned in Luke as containing Abraham's Bosom and Hades. This was a parable based off of a commonly known and understood pagan fable found in the Gemara Babylonicum, which drew from pagan concepts of Hades and the afterlife. It was popular and known among the Pharisees and Sadducees which Jesus was talking to when Jesus said this parable. As such, being a parable drawn from a commonly-known fable of the time, it was never meant to overshadow the rest of the Bible (which never mentions Sheol having sections) and be used to teach doctrine in this way. The 2 sides of Hades in the parable are analogously representative of the 2 places one may go after the resurrection of the dead and the judgment. But to use this parable to teach that Sheol has compartments is like using the parable of the sheep and goats to say all Christians will be turned into literal sheep in Heaven. That is not the case, it is just a parable in that sense. And so because nowhere in the entire Bible is it taught that Sheol has sections, we can safely disregard this section of First Enoch as unreliable and uninspired.

There is an even more convincing point to be made that shows chapter 22 is unreliable historically, and uninspired. It states "but their spirits shall not be slain in the day of judgment nor shall they be raised from thence" (thence being Sheol). What this tries to say is that some of the dead will not be raised out of Sheol at the judgment. That contradicts the Bible very clearly. And so chapters 20 and 21 I feel I have shown somewhat convincingly are not reliable, and I hope it is glaringly obvious that chapter 22 is definitely not reliable nor inspired. So by this point, erring on the side of caution, the rest of First Enoch BW has to be thrown out as unreliable as well. There is simply no way to safely accept any of the rest of it as reliable, because the established historically reliable section is over and done with, with no connection to later portions.

So for that reason I'm not going to bother doing analysis on the rest of First Enoch BW.

It is my belief that the first 16 chapters of First Enoch, the Book of the Watchers, should be taken as mostly being historically reliable, as they were very likely accepted by the apostles as such. But I only think this about the first 16 chapters. This reliability I think should especially be said about the sections which the apostles clearly reference to in the Bible.  There is nothing in the rest of First Enoch that I see as being possibly reliable or inspired scripture, nor do I know of any Biblical reason to consider examining it, so I am not. The rest doesn't tie into the Bible like First Enoch the Book of the Watchers 1-16.

However, I do not think that First Enoch Book of the Watchers 1-16 should be taken as inspired scripture, as the book exists today, because of the verse that reads "3000 ells" (300 ft.) for the height of the giant Nephilim. This is five times the height of the tallest dinosaur ever found (60 ft.), and it seems unlikely that any giant could reach this height. This verse seems to be corrupted, probably from "300 ells" (30 ft.) in some copying error, possibly. So the first 16 chapters can not be assumed to be uncorrupted from the original, in total, despite that certain key information referenced by the apostles seems historically reliable and drawn from by them.
So, I think heavy weight of historical reliability should be given to chapters 1-16 especially in the parts referenced to in the NT. This is information which is found nowhere else in the Bible, yet referenced in the Bible as historically reliable. I think these sections are in some ways historically reliable and were accepted by the apostles and early church. However, these sections could not be accepted in total with the same trustworthiness as inspired scripture.
