Genesis 2:21-25

21 And the LORD God caused a deep sleep to fall on Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof;

22 And the rib, which the LORD God had taken from man, made he a woman, and brought her to the man.

23 And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man.

24 Therefore shall a man leave his father and his mother, and shall join to his wife: and they shall be one flesh.

25 And they were both naked, the man and his wife, and were not ashamed.
