Genesis 1:2-8
English Standard Version
3And God said, "Let there be light," and there was light.
4And God saw that the light was good. And God 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 an expanse in the midst of the waters, and let it separate the waters from the waters."
7And God made the expanse and separated the waters that were under the expanse from the waters that were above the expanse. And it was so.
8And God called the expanse Heaven. And there was evening and there was morning, the second day.
