Genesis 6:1-3
Genesis 6: 1 to 3
1 Now when humankind began to multiply on the face of the ground and daughters were born to them,
2 then the sons of God saw that the daughters of men were good and they took for themselves wives, any they chose.
3 Then ADONAI said, “My Spirit will not remain with humankind forever, since they are flesh. So their days will be 120 years.
