A wife's ketubah [is collected by her] from the worst property—words of Rabbi Yehudah. Rabbi Shimon says: Why did they say that a wife's ketubah [is collected] from the worst property? [Because] more than a man wants to marry, a woman wants to be married. Furthermore, a woman's shame is greater than that of a man. If so, she shouldn't have a ketubah at all! Rather, [it is because] a wife is divorced willingly or unwillingly, but a man only divorces willingly.
