Genesis 1:18-22

to be in charge of the day and in charge of the night, and to separate light from darkness. God saw that it was good.

So there was evening, and then the morning, making day four.

God said, “Let the waters be full of living creatures, and let birds fly above the earth in the sky.”

So God created huge sea creatures and all the living things that swim and fill the waters, each one according to its own kind; and every bird that flies, each one according to its own kind. God saw that it was good.

God blessed them and said, “Reproduce and increase, and fill the waters of the seas, and let the birds increase on the earth.”
