In context
20And God said, “Let the waters teem with living creatures, and let birds fly above the earth in the open expanse of the sky.” 21So God created the great sea creatures and every living thing that moves, with which the waters teemed according to their kinds, and every winged bird after its kind. And God saw that it was good. 22Then God blessed them and said, “Be fruitful and multiply and fill the waters of the seas, and let birds multiply on the earth.” 23And there was evening, and there was morning — the fifth day.
