“All creatures great and small”
20 God said, “Let the waters abound with living creatures, and let birds fly above the earth in the open expanse of the sky.” 21 God created the large sea creatures and every living creature that moves, with which the waters swarmed, after their kind, and every winged bird after its kind. God saw that it was good. 22 God blessed them, saying, “Be fruitful, and multiply, and fill the waters in the seas, and let birds multiply on the earth.” 23 There was evening and there was morning, a fifth day.
24 God said, “Let the earth produce living creatures after their kind, livestock, creeping things, and animals of the earth after their kind;” and it was so. 25 God made the animals of the earth after their kind, and the livestock after their kind, and everything that creeps on the ground after its kind. God saw that it was good.
