Book of Enoch (1 Enoch) 71:1
And it came to pass after this that my spirit was translated And it ascended into the heavens: And I saw the holy sons of God. They were stepping on flames of fire: Their garments were white [and their raiment], And their faces shone like snow.
Background and history of Book of Enoch (1 Enoch), and issues with this book.
R. H. Charles, The Book of Enoch (London: SPCK, 1917), public domain. The verse text is the English Wikisource transcription of that translation. Charles’s editorial signs are kept. He rearranges some verses in chapters 5, 39, 90, 91, and 106, so those chapters are not a straight 1, 2, 3 sequence.
