Genesis 2:21-25 New Revised Standard Version (NRSV)
21 So the Lord God caused a deep sleep to fall upon the man, and he slept; then he took one of his ribs and closed up its place with flesh. 22 And the rib that the Lord God had taken from the man he made into a woman and brought her to the man. 23 Then the man said,
24 Therefore a man leaves his father and his mother and clings to his wife, and they become one flesh. 25 And the man and his wife were both naked, and were not ashamed.
