Genesis 1:14-18

14Then God said, “Let lights in the expanse of the sky be for separating the day from the night. They will be for signs and for seasons and for days and years.

15They will be for lights in the expanse of the sky to shine upon the land.” And it happened so.

16Then God made the two great lights—the greater light for dominion over the day, and the lesser light as well as the stars for dominion over the night.

17God set them in the expanse of the sky to shine on the land

18and to have dominion over the day and over the night and to separate the light from the darkness. And God saw that it was good.
