Bava Metzia 46 - April 14, 6 Nissan

Today's daf is dedicated to the safety of Israel from the Iranian attack.  Today's daf is sponsored by Mitzi and David Geffen in loving memory of Mitzi's mother, Ruth Toll Lock, Rut bat Miriam and Avraham z"l on her 38th yahrzeit. "She was a loving wife, mother, and mother-in-law; a devoted Zionist and wonderful educator in Harrisburg, PA. All 4 of her children made Aliyah and her many grandchildren and great-grandchildren, as well as her great-great-grandchild, all live in Israel!" Rav Papa holds that a coin be acquired through a kinyan chalipin. A Minsha in Maaser Sheni 4:5 is raised as a difficulty on Rav Papa's position. Rav Papa eventually switches his position as is proven by Rav Papa's actions in a particular situation when he was trying to get back money from a loan. The Gemara returns to the previous discussion of whether or not a coin can be used to effect a kinyan chalipin (symbolic kinyan). Ulla, Rabbi Asi and Rabbi Yochanan ruled that money cannot be used. Rabbi Abba raises a difficulty from a braita against Ulla and Rabbi Abba himself suggests one possible resolution and Rav Ashi suggests another. Another source (Mishna in Kiddushin) is brought to raise a difficulty with Ulla, Rabbi Ami and Rabbi Yochanan's positions but is resolved. However, the resolution is only consistent with Rav Sheshet's position that chalipin can be effected with produce (and other moveable items that are not considered a kli), but not with Rav Nachman's position that chalipin cannot be effected with produce. How can the Mishna be explained according to Rav Nachman? The explanation given for Rav Nachman accords with Rabbi Yochanan's opinion in his debate with Reish Lakish about whether money effect a kinyan (acquisition) by Torah law. Both agree that practically money does not effect a transaction, however, Rabbi Yochanan holds that it is only because of a rabbinic decree, that does not apply in rare circumstances. Reish Lakish's explanation of a line in our Mishna is bought as a third source to raise a difficulty against the position that money cannot be used as chalipin. This difficulty is resolved as well.
