Book of Enoch (1 Enoch) 93:4
And after me there shall arise in the second week great wickedness, And deceit shall have sprung up; And in it there shall be the first end. And in it a man shall be saved; And after it is ended unrighteousness shall grow up, And a law shall be made for the sinners.
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.
