16. God made two powerful lights, the brighter one to rule the day and the other to rule the night. He also made the stars.
17. Then God put these lights in the sky to shine on the earth,
18. to rule day and night, and to separate light from darkness. God looked at what he had done, and it was good.
19. Evening came and then morning—that was the fourth day.
20. God said, “I command the sea to be full of living creatures, and I command birds to fly above the earth.”
21. So God made the giant sea monsters and all the living creatures that swim in the sea. He also made every kind of bird. God looked at what he had done, and it was good.
