Genesis 1:19-21

19 There was evening, and then there was morning. This was the fourth day.

20 Then God said, “Let the water be filled with many living things, and let there be birds to fly in the air over the earth.”

21 So God created the large sea animals.[6] He created all the many living things in the sea and every kind of bird that flies in the air. And God saw that this was good.
