Genesis 1:15

1:14 Then God said, "Let there be lights in the firmament of the heavens to divide the day from the night; and let them be for signs and seasons, and for days and years;

1:15 and let them be for lights in the firmament of the heavens to give light on the earth"; and it was so.

1:16 Then God made two great lights: the greater light to rule the day, and the lesser light to rule the night. He made the stars also.
