Genesis 2:20-22

20The man gave names to all livestock and to the birds of the heavens and to every beast of the field. But for Adam there was not found a helper fit for him.

21So the Lord God caused a deep sleep to fall upon the man, and while he slept took one of his ribs and closed up its place with flesh.

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