Book of Enoch (1 Enoch) 94:9
Ye have committed blasphemy and unrighteousness, And have become ready for the day of slaughter, And the day of darkness and the day of the great judgement.
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.
