1 Enoch 72:35

In 1 translation

1En-Charles

And this is the law and the course of the sun, and his return as often as he returns sixty times and rises, i.e. the great luminary which is named the sun, for ever and ever.i.e. two months in each portal, one month on his northward and one month on his southward journey. The author disregards for the time being the extra day in the first, third, fourth, and sixth portals.
