Genesis 2:20-22 (NKJV)
[20] So Adam gave names to all cattle, to the birds of the air, and to every beast of the field. But for Adam there was not found a helper comparable to him.
[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 in its place.
[22] Then the rib which the Lord God had taken from man He made into a woman, and He brought her to the man.
