Genesis 1:18-20

18 and to rule over the day and over the night, and to separate the light from the darkness. And Elohim saw that it was good.

19 And there came to be evening and there came to be morning, the fourth day.

20 And Elohim said, “Let the waters teem with shoals of living beings, and let birds fly above the earth on the face of the expanse of the heavens.”
