God gave them his blessing and said: Have a lot of children! Fill the earth with people and bring it under your control. Rule over the fish in the ocean, the birds in the sky, and every animal on the earth.
Didn't God create you to become like one person with your wife? And why did he do this? It was so you would have children, and then lead them to become God's people. Don't ever be unfaithful to your wife.
