Enoch 79

1 And now, my son, I have shown you everything, and the law of all the stars of heaven is complete. 2 And he showed me all their laws: for every day, and for every season of its rule, and for every year, and for its going forth, and for the order prescribed to it every month and every week.

3 And the waning of the moon, which takes place in the sixth portal: for in this sixth portal her light is completed, and after that the waning begins. [a] 4 And the waning which takes place in the first portal in its season, until 177 days are completed: reckoned by weeks, twenty-five weeks and two days. 5 She falls behind the sun and the order of the stars by exactly five days in the course of one period, and when this place which you see has been traversed. [b] 6 Such is the picture and sketch of every luminary that Uriel the chief messenger, who is their leader, showed to me. [c]
