Book of Enoch (1 Enoch) 41:5
And I saw the chambers of the sun and moon, whence they proceed and whither they come again, and their glorious return, and how one is superior to the other, and their stately orbit, and how they do not leave their orbit, and they add nothing to their orbit and they take nothing from it, and they keep faith with each other, in accordance with the oath by which they are bound together.

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.
