Book of Enoch (1 Enoch) 67:9
And in proportion as the burning of their bodies becomes severe, a corresponding change shall take place in their spirit for ever and ever; for before the Lord of Spirits none shall utter an idle word.
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.
