Genesis 1:14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:
15 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.
16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.
17 And God set them in the firmament of the heaven to give light upon the earth,
18 And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.
19 And the evening and the morning were the fourth day.

Psalms 81:3 Blow up the trumpet in the new moon, in the time appointed, on our solemn feast day.
4 For this was a statute for Israel, and a law of the God of Jacob.
5 This he ordained in Joseph for a testimony, when he went out through the land of Egypt: where I heard a language that I understood not.

Ecclesiasticus 43:6 He made the moon also to serve in her season for a declaration of times, and a sign of the world.
7 From the moon is the sign of feasts, a light that decreaseth in her perfection.
8 The month is called after her name, increasing wonderfully in her changing, being an instrument of the armies above, shining in the firmament of heaven;
9 The beauty of heaven, the glory of the stars, an ornament giving light in the highest places of the Lord.
10 At the commandment of the Holy One they will stand in their order, and never faint in their watches.
