Here is a translation of Genesis 2:1-6:
Now it came about that men began to multiply over the face of the earth, and daughters were born to them. These sons of God saw that girls were beautiful, and they took them as wives as they chose. So then the Lord said, "My Spirit will not contend with man indefinitely, because in his waywardness he is corrupt. He has a hundred and twenty more years remaining." Arrogant men were on the earth in those days - and also afterwards - when these sons of God went to the daughters of men and had children by them. They were the tyrants of old, men of reputation. The Lord saw how great man's wickedness on the earth had become, and that every inclination of the thoughts of his heart was only evil all the time. The Lord was grieved that he had made man on the earth, and his heart was filled with pain.
