Genesis 1:14 - 1:18
14 Then God said, “Let there be lights in the expanse of the heavens to separate 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 expanse of the heavens to give light on the earth”; and it was so. 16 So God made the two great lights, the greater light to rule the day, and the lesser light to rule the night, and also the stars. 17 And God placed them in the expanse of the heavens to give light on the earth, 18 and to rule the day and the night, and to separate the light from the darkness; and God saw that it was good.
