Genesis 1:3-8

3And 1God said, Let there be light. And there was light.

4And 2God saw the light that it was good; and 3God divided between the light and the darkness.

5And 4God called the light Day, and the darkness he called Night. And there was evening, and there was morning — the first day.

6And 5God said, Let there be an expanse in the midst of the waters, and let it be a division between waters and waters.

7And 6God made the expanse, and divided between the waters that are under the expanse and the waters that are above the expanse; and it was so.

8And 7God called the expanse Heavens. And there was evening, and there was morning — a second day.
