The Book of Enoch is an ancient Jewish apocalyptic work traditionally attributed to Enoch, the great-grandfather of Noah. It is canonical only in the Ethiopian Orthodox Tewahedo Church and the Eritrean Orthodox Tewahedo Church. The original language was either Hebrew or Aramaic, and the only complete extant version is in Ge'ez. This translation by R.H. Charles (1917) remains the standard scholarly English translation. The book is pseudepigraphal and was highly influential on early Christian and Jewish mystical thought. It is not included in the Protestant, Catholic, or most Orthodox canons.
Enoch
Chapter 16
From the days of the slaughter and destruction and death 'of the giants', from the souls of whose flesh the spirits, having gone forth, shall destroy without incurring judgement—thus shall they destroy until the day of the consummation, the great 'judgement' in which the age shall be consummated over the Watchers and the godless, yea, shall be wholly consummated."
And now as to the Watchers who have sent thee to intercede for them, who had been 'aforetime' in heaven, (say to them):
"You have been in heaven, but fall the mysteries had not yet been revealed to you, and you knew worthless ones, and these in the hardness of your hearts you have made known to the women, and through these mysteries women and men work much evil on earth."
Say to them therefore: "You have no peace."
