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 And God said, “Let the waters teem with living creatures, and let birds fly above the earth in the open expanse of the sky.”

21 So God created the great sea creatures and every living thing that moves, with which the waters teemed according to their kinds, and every winged bird after its kind. And God saw that it was good.

22 Then God blessed them and said, “Be fruitful and multiply and fill the waters of the seas, and let birds multiply on the earth.”

23 And there was evening, and there was morning—the fifth day.

24 And God said, “Let the earth bring forth living creatures according to their kinds: livestock, land crawlers, and beasts of the earth according to their kinds.” And it was so.
