Genesis 1:14-19

¹⁴Then God said, “Let there be lights in the expanse of the heavens to separate the day from the night, and they shall serve as signs and for seasons, and for days and years; ¹⁵and they shall serve as lights in the expanse of the heavens to give light on the earth”; and it was so. ¹⁶God made the two great lights, the greater light to govern the day, and the lesser light to govern the night; He made the stars also. ¹⁷God placed them in the expanse of the heavens to give light on the earth, ¹⁸and to govern the day and the night, and to separate the light from the darkness; and God saw that it was good. ¹⁹And there was evening and there was morning, a fourth day.
