Book of Enoch (1 Enoch) 69:11
For men were created exactly like the angels, to the intent that they should continue pure and righteous, and death, which destroys everything, could not have taken hold of them, but through this their knowledge they are perishing, and through this power †it is consuming me†.
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.
