Genesis

And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.

And God blessed Noah and his sons, and said unto them, Be fruitful, and multiply, and replenish the earth.

Now these are the generations of the sons of Noah, Shem, Ham, and Japheth: and unto them were sons born after the flood.

And Shem lived after he begat Arphaxad five hundred years, and begat sons and daughters.

Take ye wives, and beget sons and daughters; and take wives for your sons, and give your daughters to husbands, that they may bear sons and daughters; that ye may be increased there, and not diminished.
