Genesis 1:3-8

3And God said, “Let there be light,” and there was light. 4God saw that the light was good, and he separated the light from the darkness.

5God called the light “day,” and the darkness he called “night.” And there was evening, and there was morning—the first day. 6And God said, “Let there be a vault between the waters to separate water from water.” 7So God made the vault and separated the water under the vault from the water above it. And it was so.

8God called the vault “sky.” And there was evening, and there was morning—the second day.
