פירוש על קידושין 7:20

Mar bar Rav Ashi points out that we could have learned that a girl who is a bogeret goes out from her master’s authority by a kal vehomer argument. A girl who becomes 12 and has hit puberty goes free from her master but, if she is living in her father’s domain, is not free from his authority. But a bogeret, one who reaches majority age, goes free even from her father’s domain. All the more so she would go free from the domain of her master. So why do we need a midrash to teach us what we would already know. Obviously any type of bogeret, whether she is an aylonit (a woman who does not hit puberty) or not, goes free.

"Being a bogeret that takes her out of the authority of the father..." [Problem:] But if you say: The death of the father breaks the ק״ו since it takes her out of the authority of her father but does not take her out of the authority of her master, solution: It would be possible to object: The death of the father that has involves no bodily change, you would say the same about bogrut that involves bodily change!?
