Enoch 73

1 And after this law I saw another law, dealing with the smaller luminary, which is named the Moon. 2 And her circumference is like the circumference of heaven, and the chariot she rides in is driven by the wind, and light is given to her in a definite measure. [a] 3 And her rising and her setting change every month, and her days are like the days of the sun, and when her light is uniform it amounts to the seventh part of the light of the sun. [b]

4 And thus she rises. Her first phase in the east comes out on the thirtieth morning, and on that day she becomes visible and counts for you as the first phase of the moon on the thirtieth day, together with the sun in the portal where the sun rises. 5 And the one half of her goes out by a seventh part, and her whole circumference is empty, without light, except for one-seventh part of it and the fourteenth part of her light. [c] 6 And when she receives one-seventh part of the half of her light, her light amounts to one-seventh part and the half of it. 7 And she sets with the sun, and when the sun rises the moon rises with him and receives the half of one part of light. And on that night, at the beginning of her morning — the beginning of the lunar day — the moon sets with the sun and is invisible that night, with the fourteen parts and the half of one of them. 8 And she rises on that day with exactly a seventh part, and comes out and draws away from the rising of the sun, and through her remaining days she grows bright in the remaining thirteen parts.
