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.'

This is probably the most descriptive section, except for Chapters 68 & 69

1 Enoch 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 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
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 judgement and of their consummation, till the judgement 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.

The son of Lamech is naturally Noah. It is thought that the major source of the first part of the Watchers narrative (chs 6 -- 11) was a now lost book of Noah. In fact, Enoch doesn't make his abrupt entrance into the Watchers narrative until ch 12.This chapter keeps the various strands of the narrative
