Which is a positive time-caused mitzvah [for which women/wives are exempt]? Sukkah, lulav and tefilin. Which is a positive non-time-caused mitzvah? [Returning a] lost object, sending away the mother bird [in order to take the eggs], [setting up] a railing [on your roof] and tzitzit. Rabbi Shimon exempts wives from tzitzit because it is a positive time-caused mitzvah. Which is a mitzvah of the son about [his] father? Feeding, giving drink, clothing, anointing, taking out and bringing in, washing his face, hands and legs. [This applies to anyone] whether a man or wife, except that a man has the opportunity to do it, but a wife does not have the opportunity to do it because others [her husband] have authority over her. What is a mitzvah of the father about [his] son? To circumcise him, redeem him [with 5 selaim if he is a firstborn], to teach him Torah, to teah him a trade and to marry him to a wife. Some say: Also to swim in the river. Rabbi Yehudah says: Anyone who doesn't teach his son a trade teaches him banditry.
