Genesis 2:21-24

21 Yahweh God caused a deep sleep to fall on the man, and he slept; and he took one of his ribs, and closed up the flesh in its place.  22 He made the rib, which Yahweh God had taken from the man, into a woman, and brought her to the man.  23 The man said, "This is now bone of my bones, and flesh of my flesh. She will be called Woman, because she was taken out of Man."  24 Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh.
