Genesis 2:23

23.And Adam said, etc It is demanded whence Adam derived this knowledge since he was at that time buried in deep sleep. If we say that his quickness of perception was then such as to enable him by conjecture to form a judgment, the solution would be weak. But we ought not to doubt that God would make the whole course of the affair manifest to him, either by secret revelation or by his word; for it was not from any necessity on God’s part that He borrowed from man the rib out of which he might form the woman; but he designed that they should be more closely joined together by this bonds which could not have been effected unless he had informed them of the fact. Moses does not indeed explain by what means God gave them this information; yet unless we would make the work of God superfluous, we must conclude that its Author revealed both the fact itself and the method and design of its accomplishment. The deep sleep was sent upon Adam, not to hide from him the origin of his wife, but to exempt him from pain and trouble, until he should receive a compensation so excellent for the loss of his rib.

This is now bone of, etc (149) In using the expression הפעם (hac vice,) Adam indicates that something had been wanting to him; as if he had said, Now at length I have obtained a suitable companion, who is part of the substance of my flesh, and in whom I behold, as it were, another self. And he gives to his wife a name taken from that of man, (150) that by this testimony and this mark he might transmit a perpetual memorial of the wisdom of God. A deficiency in the Latin language has compelled the ancient interpreter to render אשה (ishah,) by the word virago. It is, however, to be remarked, that the Hebrew term means nothing else than the female of the man.
