Book of Enoch (1 Enoch) 56:7
But the city of my righteous shall be a hindrance to their horses. And they shall begin to fight among themselves, And their right hand shall be strong against themselves, And a man shall not know his brother, Nor a son his father or his mother, Till there be no number of the corpses through their slaughter, And their punishment be not in vain.
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.
