Enoch 19

1 And Uriel said to me, “Here is where the messengers will stand — the ones who joined themselves with women. Their spirits, taking many different forms, are defiling mankind and will lead them astray into sacrificing to demons as gods. Here they will stand until the day of the great judgment, in which they will be judged, until they are brought to an end. [a] 2 And the women, too, of the messengers who went astray will become sirens.”

3 And I, Enoch, alone saw the vision, the ends of all things; and no one will see as I have seen. [b]
