Gittin 25 - Shabbat June 10, 21 Sivan Daf Yomi for Women - Hadran

Study Guide Gittin 25
There are four opinions about whether a get that was not written li’shma disqualifies the woman from being married to a kohen. The debate is about which cases of li’shma, if any, would disqualify and which would not. Why? Rabbi Yochanan’s opinion is consistent with his opinion regarding the distribution of inheritance property. Why was it necessary for him to teach both cases if theoretically, one could have learned from one case to the other? Rav Hoshaya asked a question regarding laws of retroactive designation (breira) for writing a get li’shma. Rav Yehuda answered him from our Mishna that laws of retroactive designation do not work. Rav Hoshaya questioned this answer from a Mishna in Pesachim where rules of retroactive designation seem to work. However, Rav Yehuda explains that the Pesachim case has nothing to do with the rules of breira. Abaye questions the whole discussion between Rav Hoshaya and Rav Yehuda as the cases are very different as some relate to a later decision made by the person himself, as opposed to others which are dependent on some other person and shouldn’t laws of breira be different in each of those types of cases? Rava disagrees and thinks there would be no reason to distinguish. Still, Rav Hamnuna tries to prove him wrong as both Rav Yehuda and Rabbi Shimon hold that breira does not apply in a case where the decision is made by the owner, as can be proven from the case of wine from which tithes weren’t taken, but does apply in cases where the decision was based on someone else.
