Genesis 1:22 Meaning and Commentary

Genesis 1:22

And God blessed them
With a power to procreate their kind, and continue their species, as it is interpreted in the next clause; saying, be fruitful, and multiply, and fill the waters in the
seas:
and these creatures do multiply exceedingly, and vast quantities there are of them in the mighty waters, though the consumption of some sorts of them is very great. Our English word "fish" is derived from the Hebrew word (vwp) , "fush", which signifies to multiply and increase: and let fowl multiply in the earth;
as they did, and continue to do to this day.

Genesis 1:22 In-Context

20 Then God said, “Let the waters swarm with fish and other life. Let the skies be filled with birds of every kind.”

21 So God created great sea creatures and every living thing that scurries and swarms in the water, and every sort of bird—each producing offspring of the same kind. And God saw that it was good.

22 Then God blessed them, saying, “Be fruitful and multiply. Let the fish fill the seas, and let the birds multiply on the earth.”

23 And evening passed and morning came, marking the fifth day.

24 Then God said, “Let the earth produce every sort of animal, each producing offspring of the same kind—livestock, small animals that scurry along the ground, and wild animals.” And that is what happened.
