Book of Enoch (1 Enoch) 73:7
And she sets with the sun, and when the sun rises the moon rises with him and receives the half of one part of light, and in that night in the beginning of her morning [in the commencement of the lunar day] the moon sets with the sun, and is invisible that night with the fourteen parts and the half of one of them.
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.
