Sforno on Genesis 2:22/ספורנו על בראשית ב׳:כ״ב

1ויבן ה' אלוקים את הצלע לאשה, it was someone possessing the features of a human being, much like those of a man. She would be different from man only in some external physical features. She would possess the same ability to perfect her personality as did man.
