And from thence I went towards the west to the ends of the earth, and saw there three portals of the heaven open such as I had seen in the †east†, the same number of portals, and the same number of outlets.

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.
