1 Enoch 55

And after that the Head of Days repented and said: ‘In vain have I destroyed all who dwell on the earth.’

And He sware by His great name: ‘Henceforth I will not do so to all who dwell on the earth, and I will set a sign in the heaven: and this shall be a pledge of good faith between Me and them for ever, so long as heaven is above the earth. And this is in accordance with My command.

LV. 3-LVI. 4. Final Judgement of Azazel, the Watchers and their children.

When I have desired to take hold of them by the hand of the angels on the day of tribulation and pain because of this, I will cause My chastisement and My wrath to abide upon them, saith God, the Lord of Spirits.

Ye †mighty kings† who dwell on the earth, ye shall have to behold Mine Elect One, how he sits on the throne of glory and judges Azâzêl, and all his associates, and all his hosts in the name of the Lord of Spirits.’
