The Book of Enoch 77

¹🔗nd Uriel showed me another law: when light is transferred to the moon, and on which side it is transferred to her by the sun.

²🔗 _Recapitulation of several of the Laws._

³🔗 And on the first day she is called the new moon, for on that day the light rises upon her.

⁴🔗 She becomes full moon exactly on the day when the sun sets in the west, and from the east she rises at night, and the moon shines the whole night through till the sun rises over against her and the moon is seen over against the sun.

⁵🔗 On the side whence the light of the moon comes forth, there again she wanes till all the light vanishes and all the days of the month are at an end, and her circumference is empty, void of light.

⁶🔗 And three months she makes of thirty days, and at her time she makes three months of twenty-nine days each, in which she accomplishes her waning in the first period of time, and in the first portal for one hundred and seventy-seven days.

⁷🔗 And in the time of her going out she appears for three months (of) thirty days each, and for three months she appears (of) twenty-nine each.

⁸🔗 At night she appears like a man for twenty days each time, and by day she appears like the heaven, and there is nothing else in her save her light. LXXIX-LXXX.

⁹🔗 And in her waning (the moon) decreases on the first day to fourteen parts of her light, on the second to thirteen parts of light, on the third to twelve, on the fourth to eleven, on the fifth to ten, on the sixth to nine, on the seventh to eight, on the eighth to seven, on the ninth to six, on the tenth to five, on the eleventh to four, on the twelfth to three, on the thirteenth to two, on the fourteenth to the half of a seventh, and all her remaining light disappears wholly on the fifteenth.

¹⁰🔗 And in certain months the month has twenty-nine days and once twenty-eight.
