Genesi 1:21

And God created great whales, and every living creature that moveth, which the (q) waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that [it was] good.

(q) The fish and fowls had both one beginning, in which we see that nature gives place to God's will, in that the one sort is made to fly about in the air, and the other to swim beneath in the water.
