Genesis 1:20-22

And God said, Let the waters swarm with swarms of living creatures, and let birds fly above the earth in the open firmament of heaven. And God created the great sea-monsters, and every living creature that moveth, wherewith the waters swarmed, after their kind, and every winged bird after its kind: and God saw that it was good. And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let birds multiply on the earth.
