Adam's rib

(Matthew Henry)

"Then the Lord God made a woman from the rib
 He had taken out of the man, and He brought
 her to the man." Genesis 2:22

Eve was not taken out of Adam's head to top him,
neither out of his feet to be trampled on by him;
but out of his side to be equal with him,
under his arm to be protected by him,
and near his heart to be loved by him.
