Adam Clarke, on Gen 2:21

“Then the Lord God cast a deep sleep upon Adam: and when he was fast asleep, he took one of his ribs, and filled up flesh for it.”

“The Lord God caused a deep sleep to fall upon Adam, etc. - This was neither swoon nor ecstasy, but what our translation very properly terms a deep sleep. And he took one of his ribs - It is immaterial whether we render צלע tsela a rib, or a part of his side, for it may mean either: some part of man was to be used on the occasion, whether bone or flesh it matters not; though it is likely, from verse Gen 2:23, that a part of both was taken; for Adam, knowing how the woman was formed, said, This is flesh of my flesh, and bone of my bone. God could have formed the woman out of the dust of the earth, as he had formed the man; but had he done so, she must have appeared in his eyes as a distinct being, to whom he had no natural relation. But as God formed her out of a part of the man himself, he saw she was of the same nature, the same identical flesh and blood, and of the same constitution in all respects, and consequently having equal powers, faculties, and rights. This at once ensured his affection, and excited his esteem.”
