Genesis 6:1-9

The number of people on earth began to grow, and daughters were born to them. When the sons of God saw that these girls were beautiful, they married any of them they chose. The LORD said, “My Spirit will not remain in human beings forever, because they are flesh. They will live only 120 years.” The Nephilim were on the earth in those days and also later. That was when the sons of God had sexual relations with the daughters of human beings. These women gave birth to children, who became famous and were the mighty warriors of long ago. The LORD saw that the human beings on the earth were very wicked and that everything they thought about was evil. He was sorry he had made human beings on the earth, and his heart was filled with pain. So the LORD said, “I will destroy all human beings that I made on the earth. And I will destroy every animal and everything that crawls on the earth and the birds of the air, because I am sorry I have made them.” But Noah pleased the LORD. This is the family history of Noah. Noah was a good man, the most innocent man of his time, and he walked with God.
