G-d said, “Let the waters swarm with swarms of living creatures, and let birds fly above the earth in the expanse of Heaven. G-d 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. G-d saw that it was good.
G-d blessed them, saying, “Be fruitful, and multiply, and fill the waters in the seas, and let the birds multiply on the earth.” There was evening and there was morning, a fifth day. (Breishit 1:20–23)
