1 Enoch 21:5

1 And I proceeded to where things were chaotic. 2 And I saw there something horrible: I saw neither a heaven above nor a firmly founded earth, but a place chaotic and horrible. 3 And there I saw seven stars of the heaven bound together in it, like great mountains and burning with fire. 4 Then I said: 'For what sin are they bound, and on what account have they been cast in hither?' 5 Then said Uriel, one of the holy angels, who was with me, and was chief over them, and said: 'Enoch, why dost thou ask, and why art thou eager for the truth? 6 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, the time entailed by their sins, are consummated.'

New Testament

Jude 1:13

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. 11 Woe to them! For they have traveled down Cain’s path, and because of greed have abandoned themselves to Balaam’s error; hence, they will certainly perish in Korah’s rebellion. 12 These men are dangerous reefs at your love feasts, feasting without reverence, feeding only themselves. They are waterless clouds, carried along by the winds; autumn trees without fruit—twice dead, uprooted; 13 wild sea waves, spewing out the foam of their shame; wayward stars for whom the utter depths of eternal darkness have been reserved.
