One cannot divide inheritance at night. \u00a0What exactly this statement means is explained by the gemara, based on a braita and a statement made by Rav Yehuda and Rav Hisda. \u00a0The statement of Rav Yehuda relates to the concept discussed in other places that a witness can’t also function as a judge. \u00a0What exactly is meant by a witness is a subject of debate among the commentaries. \u00a0When one makes a kinyan, there is a certain timeframe in which one side can change their minds. \u00a0What that timeframe is is a subject of debate between\u00a0Rabba and Rav Yosef. \u00a0 What type of kinyan\u00a0the gemara is referring to is debated by the commentaries. \u00a0 Why is the mishna repeating cases that can be inferred from the previous section? \u00a0Rabbi Yochanan says in the name of Rabbi Yehuda ben Shimon that a woman inherits from her son. \u00a0However Rabbi Yochanan questions that this\u00a0goes against the mishna. \u00a0Rabbi Yehuda rejects our mishna and says that he doesn’t know who wrote our mishna!<\/p>\n
