Genesis 2:21

Here we have, I. The making of the woman, to be a help-meet for Adam. This was done upon the sixth day, as was also the placing of Adam in paradise, though it is here mentioned after an account of the seventh day's rest; but what was said in general (Gen 1:27), that God made man male and female, is more distinctly related here. Observe, 1. That Adam was first formed, then Eve (Ti1 2:13), and she was made of the man, and for the man (Co1 11:8, Co1 11:9), all which are urged there as reasons for the humility, modesty, silence, and submissiveness, of that sex in general, and particularly the subjection and reverence which wives owe to their own husbands. Yet man being made last of the creatures, as the best and most excellent of all, Eve's being made after Adam, and out of him, puts an honour upon that sex, as the glory of the man, Co1 11:7. If man is the head, she is the crown, a crown to her husband, the crown of the visible creation. The man was dust refined, but the woman was dust double-refined, one remove further from the earth. 2. That Adam slept while his wife was in making, that no room might be left to imagine that he had herein directed the Spirit of the Lord, or been his counsellor, Isa 40:13.

deep sleep--probably an ecstasy or trance like that of the prophets, when they had visions and revelations of the Lord, for the whole scene was probably visible to the mental eye of Adam, and hence his rapturous exclamation. took one of his ribs--"She was not made out of his head to surpass him, nor from his feet to be trampled on, but from his side to be equal to him, and near his heart to be dear to him."
