Genesis 6:2-5

VIN(i) 2 The sons of God saw that the daughters of men were beautiful. They married any of them they chose. 3 And the LORD said, My Spirit shall not always plead with Man; for he indeed is flesh; but his days shall be a hundred and twenty years. 4 The NEPHILIM were on the earth in those days, and also afterward, when the sons of God had sexual intercourse with the daughters of men and had children by them. They were the heroes of old, men of renown. 5 the LORD saw how great man's wickedness on the earth had become. Every inclination of the thoughts of his heart was only evil all the time.
