When mankind began to multiply on the earth and daughters were born to them,
God blessed them, and God said to them, “Be fruitful, multiply, fill the earth, and subdue it. Rule the fish of the sea, the birds of the sky, and every creature that crawls on the earth.”
Noah was 500 years old, and he fathered Shem, Ham, and Japheth.
the sons of God saw that the daughters of mankind were beautiful, and they took any they chose as wives for themselves.
