Genesis 1:3-8

3Then God said, “Let there be light!” and there was light.

4God saw that the light was good. So God distinguished the light from the darkness.

5God called the light “day,” and the darkness He called “night.” So there was evening and there was morning—one day.

6Then God said, “Let there be an expanse in the midst of the water! Let it be for separating water from water.”

7So God made the expanse and it separated the water that was below the expanse from the water that was over the expanse. And it happened so.

8God called the expanse “sky.” So there was evening and there was morning—a second day.
