17. God placed them in the expanse of the sky to provide light on the earth,
18. to dominate the day and the night, and to separate light from darkness. And God saw that it was good.
19. Evening came and then morning: the fourth day.
20. Then God said, “Let the water swarm with living creatures, and let birds fly above the earth across the expanse of the sky.”
21. So God created the large sea-creatures and every living creature that moves and swarms in the water, according to their kinds. He also created every winged bird according to its kind. And God saw that it was good.
