Secrets of Enoch

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

Then I said: 'How fearful is the place and how terrible to look upon!'
And he said unto me 'This place is the prison of those angels
And here they'll be imprisoned forever'
FEAR GOD

1 Enoch 21:7-8
