God said, “Let there be lights in the expanse of the sky to divide the day from the night, and let them serve as markers to indicate seasons, days, and years. Let them serve as lights in the expanse of the sky to give light to the earth,” and it was so. God made the two great lights: the greater light to rule the day, and the lesser light to rule the night. He also made the stars. God set these lights in place in the expanse of the sky to provide light for the earth, to rule over the day and over the night, and to divide the light from the darkness. God saw that it was good. There was evening and there was morning—the fourth day.
