1 Enoch 12:4

1 Before these things Enoch was hidden, and no one of the children of men knew where he was hidden, and where he abode, and what had become of him. 2 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 called me--Enoch the scribe--and said to me: 4 '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 wives: "Ye have wrought great destruction on the earth: 5 And ye shall have no peace nor forgiveness of sin: and inasmuch as †they† delight themselves in †their† children, 6 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."'

New Testament

4 For certain men have secretly slipped in among you—men who long ago were marked out for the condemnation I am about to describe—ungodly men who have turned the grace of our God into a license for evil and who deny our only Master and Lord, Jesus Christ. 5 Now I desire to remind you (even though you have been fully informed of these facts once for all) that Jesus, having saved the people out of the land of Egypt, later destroyed those who did not believe. 6 You also know that the angels who did not keep within their proper domain but abandoned their own place of residence, he has kept in eternal chains in utter darkness, locked up for the judgment of the great Day. 7 So also Sodom and Gomorrah and the neighboring towns, since they indulged in sexual immorality and pursued unnatural desire in a way similar to these angels, are now displayed as an example by suffering the punishment of eternal fire. 8 Yet these men, as a result of their dreams, defile the flesh, reject authority, and insult the glorious ones. 9 But even when Michael the archangel was arguing with the devil and debating with him concerning Moses’ body, he did not dare to bring a slanderous judgment, but said, “May the Lord rebuke you!” 10 But these men do not understand the things they slander, and they are being destroyed by the very things that, like irrational animals, they instinctively comprehend.
