When human beings began to grow numerous on the earth and daughters were born to them,
God blessed them and God said to them: Be fertile and multiply; fill the earth and subdue it. Have dominion over the fish of the sea, the birds of the air, and all the living things that crawl on the earth.
When Noah was five hundred years old, he begot Shem, Ham, and Japheth.
the sons of God saw how beautiful the daughters of human beings were, and so they took for their wives whomever they pleased.
