Genesis 2:20-22

And the man gave names to all cattle, and to the birds of the heavens, and to every beast of the field; but for man there was not found a help meet for him. And Jehovah God caused a deep sleep to fall upon the man, and he slept; and he took one of his ribs, and closed up the flesh instead thereof: and the rib, which Jehovah God had taken from the man, made he a woman, and brought her unto the man.
