Genesis 1:14-16

14God said, “Let there be lights in the expanse of the sky to separate the day from the night, and let them be signs to indicate seasons and days and years,

15and let them serve as lights in the expanse of the sky to give light on the earth.” It was so.

16God made two great lights – the greater light to rule over the day and the lesser light to rule over the night. He made the stars also.
