"And if a man sells his daughter": He sells her, but she does not sell herself. For it would follow (otherwise), viz.: If a son, whose father is not permitted to sell him, sells himself, then a daughter, whose father is permitted to sell her, how much more so should she (be permitted to) sell herself! — No, this may be true of a son, who is sold for his theft, as opposed to a daughter, who is not sold for her theft.
