Genesis 2:20-24

20The man gave names to all the livestock, to the birds of the sky, and to every wild animal; but for the man no helper was found corresponding to him.

21So the Lord God caused a deep sleep to come over the man, and he slept. God took one of his ribs and closed the flesh at that place.

22Then the Lord God made the rib he had taken from the man into a woman and brought her to the man.

23And the man said: This one, at last, is bone of my bone and flesh of my flesh; this one will be called “woman,” for she was taken from man.

24This is why a man leaves his father and mother and bonds with his wife, and they become one flesh.
