Genesis 1:17-20
Genesis 1:17-20 ESV
And God set them in the expanse of the heavens to give light on the earth, to rule over the day and over the night, and to separate the light from the darkness. And God saw that it was good. And there was evening and there was morning, the fourth day. And God said, “Let the waters swarm with swarms of living creatures, and let birds fly above the earth across the expanse of the heavens.”
