And I saw there something like an invisible cloud; for by reason of its depth I could not †look over†, and I saw a flame of fire blazing brightly, and things like shining mountains circling and sweeping to and fro.

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.
