God's providence in the creation of His people:

"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. Adam lost a rib...but in lieu thereof he had a helpmeet for him, which abundantly made up his loss." Matthew Henry
