Genesis 6:1-9

When the number of people started to increase throughout the fertile land, daughters were born to them. The divine beings saw how beautiful these human women were, so they married the ones they chose. The LORD said, “My breath will not remain in humans forever, because they are flesh. They will live one hundred twenty years.” In those days, giants lived on the earth and also afterward, when divine beings and human daughters had sexual relations and gave birth to children. These were the ancient heroes, famous men. The LORD saw that humanity had become thoroughly evil on the earth and that every idea their minds thought up was always completely evil. The LORD regretted making human beings on the earth, and he was heartbroken. So the LORD said, “I will wipe off of the land the human race that I’ve created: from human beings to livestock to the crawling things to the birds in the skies, because I regret I ever made them.” But as for Noah, the LORD approved of him. These are Noah’s descendants. In his generation, Noah was a moral and exemplary man; he walked with God.
