Book of Enoch (1 Enoch) 75:4
In like manner twelve doors Uriel showed me, open in the circumference of the sun’s chariot in the heaven, through which the rays of the sun break forth: and from them is warmth diffused over the earth, when they are opened at their appointed seasons.
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.
