The Fall of the Watchers and Nephilim
In the Book of Enoch, 200 angels called Watchers, led by Semjaza, descend to Mount Hermon in Jared's (Enoch's father) time, mate with human women to birth giant Nephilim who devour mankind and corrupt the earth with forbidden arts like weaponry and sorcery, necessitating the flood.
When human beings began to increase in number on the earth and daughters were born to them, the sons of God saw that the daughters of humans were beautiful, and they married any of them they chose. Then the Lord said, “My Spirit will not contend with humans forever, for they are mortal; their days will be a hundred and twenty years.” The Nephilim were on the earth in those days — and also afterward — when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown. - Genesis 6:1–4
“The Watchers”
Angels, gods, or ETs or ??? who descended, taught metalwork, enchantment, astrology, and interbred with humankind
Why “The Watchers”? Because the humans knew there were beings watching them. They knew there was beings that were more powerful and somehow different than them who were watching them. Not really being involved directly or showing themselves, but some people, especially mystics and priests, noticed them watching…. The were just watching and not being directly involved….
The Book of Jubilees narrates the genesis of angels on the first day of Creation and the story of how a group of fallen angels mated with mortal females, giving rise to a race of giants known as the Nephilim, and then to their descendants, the Elioud.
The Ethiopian version states that the "angels" were in fact the disobedient offspring of Seth (Deqiqa Set), while the "mortal females" were daughters of Cain. This is also the view held by Clementine literature, Sextus Julius Africanus, Ephrem the Syrian, Augustine of Hippo, and John Chrysostom among many early Christian authorities.
Their hybrid children, the Nephilim in existence during the time of Noah, were wiped out by the great flood. Jubilees also states that God granted ten percent of the disembodied spirits of the Nephilim to try to lead mankind astray after the flood. According to this book, Hebrew is the language of Heaven, and was originally spoken by all creatures in the Garden, animals and man; however, the animals lost their power of speech when Adam and Eve were expelled. Following the Deluge, the earth was apportioned into three divisions for the three sons of Noah, and his sixteen grandsons. After the destruction of the Tower of Babel, their families were scattered to their respective allotments, and Hebrew was forgotten, until Abraham was taught it by the angels.
Nephilim as Offspring of Cain's Line
Some midrash and Book of Enoch variants link the giants not just to Watchers but to Cain's descendants intermarrying with Seth's, amplifying pre-flood corruption and portraying the fall's legacy as escalating violence within Adam's fractured family tree.
The Watchers' Oath on Mount Hermon
Book of Enoch recounts the angels binding themselves with a curse-oath on Mount Hermon to defy God by wedding women, initiating the chain of corruption that pollutes Adam's descendants and justifies the flood as cosmic reset.
the world’s corruption and the origin and legitimacy of knowledge.

CHAPTER VI.
1. And it came to pass when the children of men had multiplied that in those days were born unto them beautiful and comely daughters. 2. 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 and beget us children.' 3. And Semjâzâ, who was their leader, said unto them: 'I fear ye will not indeed agree to do this deed, and I alone shall have to pay the penalty of a great sin.' 4. And they all answered him and said: 'Let us all swear an oath, and all bind ourselves by mutual imprecations not to abandon this plan but to do this thing.' 5. Then sware they all together and bound themselves by mutual imprecations upon it. 6. 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 and bound themselves by mutual imprecations upon it. 7. And these are the names of their leaders: Sêmîazâz, their leader, Arâkîba, Râmêêl, Kôkabîêl, Tâmîêl, Râmîêl, Dânêl, Êzêqêêl, Barâqîjâl, Asâêl, Armârôs, Batârêl, Anânêl, Zaqîêl, Samsâpêêl, Satarêl, Tûrêl, Jômjâêl, Sariêl. 8. These are their chiefs of tens.
CHAPTER VII.
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 and enchantments, and the cutting of roots, and made them acquainted with plants. 2. And they became pregnant, and they bare great giants, whose height was three thousand ells: 3. Who consumed all the acquisitions of men. And when men could no longer sustain them, 4. the giants turned against them and devoured mankind. 5. And they began to sin against birds, and beasts, and reptiles, and fish, and to devour one another's flesh, and drink the blood. 6. Then the earth laid accusation against the lawless ones.
CHAPTER VIII.
1. And Azâzêl 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 colouring tinctures. 2. And there arose much godlessness, and they committed fornication, and they were led astray, and became corrupt in all their ways. Semjâzâ taught enchantments, and root-cuttings, Armârôs the resolving of enchantments, Barâqîjâl (taught) astrology, Kôkabêl the constellations, Ezêqêêl the knowledge of the clouds, 〈Araqiêl the signs of the earth, Shamsiêl the signs of the sun〉, and Sariêl the course of the moon. And as men perished, they cried, and their cry went up to heaven . . .
CHAPTER IX.
1. And then Michael, Uriel, Raphael, and Gabriel looked down from heaven and saw much blood being shed upon the earth, and all lawlessness being wrought upon the earth. 2. And they said one to another: 'The earth made †without inhabitant cries the voice of their crying† 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 before the Most High.".' 4. 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 ages, and Thy name holy and glorious and blessed unto all the ages! 5. 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 things, and nothing can hide itself from Thee. 6. Thou seest what Azâzêl hath done, who hath taught all unrighteousness on earth and revealed the eternal secrets which were (preserved) in heaven, which men were striving to learn: 7. And Semjâzâ, to whom Thou hast given authority to bear rule over his associates. 8. And they have gone to the daughters of men upon the earth, and have slept with the women, and have defiled themselves, and revealed to them all kinds of sins. 9. And the women have borne giants, and the whole earth has thereby been filled with blood and unrighteousness. 10. 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 wrought on the earth. 11. 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 X.
1. Then said the Most High, the Holy and Great One spake, and sent Uriel to the son of Lamech, and said to him: 2. '〈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 upon the whole earth, and will destroy all that is on it. 3. And now instruct him that he may escape and his seed may be preserved for all the generations of the world.' 4. And again the Lord said to Raphael: 'Bind Azâzêl hand and foot, and cast him into the darkness: and make an opening in the desert, which is in Dûdâêl, and cast him therein. 5. 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 not see light. 6. And on the day of the great judgement 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 Watchers have disclosed and have taught their sons. 8. And the whole earth has been corrupted through the works that were taught by Azâzêl: to him ascribe all sin.' 9. 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 battle: for length of days shall they not have. 10. 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 that each one of them will live five hundred years.' 11. And the Lord said unto Michael: 'Go, bind Semjâzâ and his associates who have united themselves with women so as to have defiled themselves with them in all their uncleanness. 12. 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 judgement and of their consummation, till the judgement that is for ever and ever is consummated. 13. 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. 15. And destroy all the spirits of the reprobate and the children of the Watchers, because 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 be full of blessing. 19. 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 ten presses of oil. 20. 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 destroy from off the earth. 21. ⌈And all the children of men shall become righteous⌉, and all nations 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 XI.
1. And in those days I will open the store chambers of blessing which are in the heaven, so as to send them down ⌈upon the earth⌉ over the work and labour of the children of men. 2. And truth and peace shall be associated together throughout all the days of the world and throughout all the generations of men.'
