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 54
And I looked and turned to another part of the earth, and saw there a deep valley with burning fire.
And they brought the kings and the mighty, and began to cast them into this deep valley.
And there mine eyes saw how they made these their instruments, iron chains of immeasurable weight.
And I asked the angel of peace who went with me, saying: 'For whom are these chains being prepared?'
And he said unto me: 'These are being prepared for the hosts of Azazel, so that they may take them and cast them into the abyss of complete condemnation, and they shall cover their jaws with rough stones as the Lord of Spirits commanded.
And Michael, and Gabriel, and Raphael, and Phanuel shall take hold of them on that great day, and cast them on that day into the burning furnace, that the Lord of Spirits may take vengeance on them for their unrighteousness in becoming subject to Satan and leading astray those who dwell on the earth.'
