Genesis 1:5-7
Genesis 1: 5 to 7
5 And Elohim called the light ‘day’ and the darkness He called ‘night.’ And there came to be evening and there came to be morning, one day.
6 And Elohim said, “Let an expanse come to be in the midst of the waters, and let it separate the waters from the waters.”
7 And Elohim made the expanse, and separated the waters which were under the expanse from the waters which were above the expanse. And it came to be so.
