Henock 72:31-32 (from the Ethiopian text, numbering by R.H Charles)
31. And on that day the sun rises from that portal, and sets in the west, and returns to the east, and rises in the third portal for one-and-thirty mornings, and sets in the west of the heaven. 32. On that day the night decreases and amounts to nine parts, and the day to nine parts, and the night is equal to the day and the year is exactly as to its days three hundred and sixty-four.
