Then God blessed them and said, “Be fruitful and multiply and fill the waters of the seas, and let birds multiply on the earth.”
God does not pray like men do; He effects what He speaks. When He blessed the fishes and fowl, commanding them to increase, He infused fecundity into their very nature by His word, and that power has taken root and borne fruit ever since.
AI summary
Creation advances toward perfection, each day producing nobler beings than the last. Fish and fowl both came from water on the fifth day, though their flesh differs; the power of the first Cause produces vastly different effects from the same source. The waters brought forth abundantly, insects and great whales alike.

Commenting on Genesis 1:20-23
God blessed them by giving them power to procreate and multiply their kind. The waters swarm with vast numbers of these creatures, though consumption of them is great; our word 'fish' itself comes from the Hebrew for multiply and increase.
