XXI. Preliminary and final place of punishment of the fallen angels (stars).
CHAPTER XXI.
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
[paragraph continues] Lord, and are bound here till ten thousand years, the time entailed by their sins, are consummated.' 7. And from thence I went to another place, which was still more horrible than the former, and I saw a horrible thing: a great fire there which burnt and blazed, and the place was cleft as far as the abyss, being full of great descending columns of fire: neither its extent or magnitude could I see, nor could I conjecture. 8. Then I said: 'How fearful is the place and how terrible to look upon!' 9. Then Uriel answered me, one of the holy angels who was with me, and said unto me: 'Enoch, why hast thou such fear and affright?' And I answered: 'Because of this fearful place, and because of the spectacle of the pain.' 10. And he said ⌈⌈unto me⌉⌉: 'This place is the prison of the angels, and here they will be imprisoned for ever.'
