Genesis 1:14-16

14And God said, “Let there be lights in the expanse of the sky to distinguish between the day and the night, and let them be signs to mark the seasons and days and years. 15And let them serve as lights in the expanse of the sky to shine upon the earth.” And it was so.

16God made two great lights: the greater light to rule the day and the lesser light to rule the night. And He made the stars as well.
