Rav Yair Kahn Daf 17b: Deleting the Date Recorded in a Get Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Daf 22a - The Dispute Between R’ Meir & R’ Elazar The Gemara (daf 22b) ascribes the dispute here to the dispute between Rabbi Elazar and Rabbi Meir as to which set of witnesses effectuate the transaction intended by a document - the eidei mesirah (“witnesses of delivery” who witness the physical transfer of the get between the two parties) or the eidei chatima (“witnesses of signing” who sign the document): Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Lo Chazra Shelichut etzel Ha-baal (24a) The Gemara in our passage assumes, as a simple matter, that shelichut where an agent cannot return to the sender is invalid. This is why a woman cannot be both her husband’s delivering agent (sheliach holakha) and her own receiving agent (sheliach kabbala). Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Rei’ach Ha-get — Scent of Divorce (24a-25a) Our Mishna brings a number of examples of gittin which are invalid because they are not “lishma,” “for her name,” a requirement derived from the term “lah,” “for her,” which the Torah uses in the context of divorce. Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Understanding Bereira (25a-26a) Our passage deals with the issue of bereira and the possibility to distinguish in this law between dependence on one’s own prerogative and dependence on anothers’ prerogative. Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Bereira Continued (25a-26a) In the previous shiur, we explained that even though a stipulation may be based on something which will happen in the future, this stipulation is not dependent on the law of bereira. This is because the law of bereira is only relevant when a characteristic element is missing from the act or the effectuation, while a stipulation is dependent on an external factor. Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn The Tofes of the Get (26a-26b) Our passage indicates, apparently, that the rules of writing a get are relevant only to the toref, the toref, the personalized essence, not the tofes (“typos” in Greek), the standardized part. Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Gittin 28b – One Who Has Been Led Out to Execution Regarding one who has been led out to execution, who according to the Mishna, we only suspect that in fact he has been killed, but we do not assume this with certainty ... Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Gittin 29a – If the Bearer of a Get Falls Ill The Gemara (ad loc.) discusses whether the possibility of sending the get by another person exists only in an emergency situation, e.g. where the original agent falls ill and is incapable of delivering it himself, or whether falling ill is just an example coming to explain why the agent cannot deliver the get himself, but in fact the get is valid even if the original agent sends it by another person, even though he did not fall ill. Rav Kahana establishes that sending the get by way of another person is valid only if the first agent fell ill. Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn The Melakha of Hotza'a Why does tractate Shabbat open with the melakha of hotza'a (carrying from one domain to another), which appears only at the end of the list of 39 forbidden labors in the Mishna? Why does the Mishna have to spell out all four possible cases of hotza'a that arise in the case of a poor man (standing outside a house) and the owner of the house (standing inside)? Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Shiur #01: Birkot Ha-nehenin: Halakhic and Philosophical Underpinnings Our Mishna begins by delineating the various types of birkot ha-nehenin (berakhot recited over certain forms of physical enjoyment). Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Shiur #02: Reciting Berakhot Over Medicine The Gemara (35b) cites the halakha posited by Shemuel and Rabbi Yochanan that one recites the berakha of borei peri ha-etz over olive oil, but it then struggles to find a case where drinking olive oil would require a berakha. Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Issur Melakha Erev Pesach Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn The Definition of Keren Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Shiur #02: Ketubot 2a "Higi'a ha-Zeman ve-Lo Nis'u" - The Delayed Marriage The mishna in the fifth chapter of Ketubot (57b) establishes that after a groom expresses his desire to marry, the first time bride is given twelve months to prepare for the wedding, and a widow is given a period of thirty days. Masekhtot - Iyun (Gittin / Pesachim)
Rav Yair Kahn Shiur #03: Ketubot 2b "Oness" in Situations of Gittin The Gemara cites two views concerning a case where a condition for the effectuation of a get is fulfilled as a result of an "oness" - a non-volitional event. Masekhtot - Iyun (Gittin / Pesachim)
