And to the west thereof there was another mountain, lower than the former and of small elevation, and a ravine ⌈deep and dry⌉ between them: and another deep and dry ravine was at the extremities of the three ⌈mountains⌉.
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.
