Genesis 2:22-25

22Adonai Elohim built the rib, which He had taken from the man, into a woman. Then He brought her to the man.

23Then the man said, “This one, at last, is bone of my bones and flesh from my flesh. This one is called woman, for from man was taken this one.”

24This is why a man leaves his father and his mother and clings to his wife; and they become one flesh.

25Now both of them were naked, the man and his wife, and they were not ashamed.
