And the rib that the LORD God had taken from the man he made into a woman and brought her to the man. Then the man said,
“This at last is bone of my bones and flesh of my flesh;
she shall be called Woman, because she was taken out of Man.”
Genesis 2:22-23 ESV
That the woman was made of a rib out of the side of Adam; not made out of his head to rule over him, nor out of his feet to be trampled upon by him, but out of his side to be equal with him, under his arm to be protected, and near his heart to be beloved.
~Matthew Henry, Commentary on Genesis
