Genesis 6:4–7

The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown.

The Lord saw how great the wickedness of the human race had become on the earth, and that every inclination of the thoughts of the human heart was only evil all the time. The Lord regretted that he had made human beings on the earth, and his heart was deeply troubled. So the Lord said, “I will wipe from the face of the earth the human race I have created—and with them the animals, the birds and the creatures that move along the ground—for I regret that I have made them.”

The Nephilim were on the earth both in those days and afterward, when the sons of God came to the daughters of mankind, who bore children to them. They were the powerful men of old, the famous men.

When the Lord saw that human wickedness was widespread on the earth and that every inclination of the human mind was nothing but evil all the time, the Lord regretted that he had made man on the earth, and he was deeply grieved. Then the Lord said, “I will wipe mankind, whom I created, off the face of the earth, together with the animals, creatures that crawl, and birds of the sky—for I regret that I made them.”

In those days, and for some time after, giant Nephilites lived on the earth, for whenever the sons of God had intercourse with women, they gave birth to children who became the heroes and famous warriors of ancient times.

The Lord observed the extent of human wickedness on the earth, and he saw that everything they thought or imagined was consistently and totally evil. So the Lord was sorry he had ever made them and put them on the earth. It broke his heart. And the Lord said, “I will wipe this human race I have created from the face of the earth. Yes, and I will destroy every living thing—all the people, the large animals, the small animals that scurry along the ground, and even the birds of the sky. I am sorry I ever made them.”

The Nephilim were upon the earth in those days, and also afterward, when the sons of God went into the daughters of humankind, and they bore children to them. These were the mighty warriors that were from ancient times, men of renown.

And Yahweh saw that the evil of humankind was great upon the earth, and every inclination of the thoughts of his heart was always only evil. And Yahweh regretted that he had made humankind on the earth, and he was grieved in his heart. And Yahweh said, “I will destroy humankind whom I created from upon the face of the earth, from humankind, to animals, to creeping things, and to the birds of heaven, for I regret that I have made them.”

There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown. And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. And it repented the Lord that he had made man on the earth, and it grieved him at his heart. And the Lord said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them.
