And the one half of her goes forth by a seventh part, and her whole circumference is empty, without light, with the exception of one-seventh part of it, (and) the fourteenth part of her light.

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.
