Menachot 31 - February 11, 24 Shvat

Ravin, the son of Chinina, said in the name of Ulla in the name of Rabbi Chanina that the law follows Rabbi Shimon Shezuri in "this" issue and anywhere else he issued a ruling. Rav Papa and Rav Nachman bar Yitzchak each identify a possible case where Rabbi Chanina ruled like Rabbi Shimon Shezuri. One suggests it was regarding how to measure 40 se'ah in a large box for purposes of impurity. The other suggests it was regarding the stringent ruling of the impurity of liquids - specifically, to which liquids this unique type of impurity extends. The Gemara brings a situation where Rabbi Shimon Shezuri mixed untithed produce with tithed produce and was told by Rabbi Tarfon to buy produce from the market to tithe upon it. In a different version, Rabbi Tarfon told him to buy produce from non-Jews. This advice is analyzed through two lenses: whether a market purchase is considered tithed by Torah law because most am ha'aretz tithe, or whether land ownership by non-Jews in Israel removes the Torah obligation of tithing the produce. Rav Papa confirms to Rav Yemar bar Shelamya that the halakha follows Rabbi Shimon Shezuri even in this specific case. A statement by Rav regarding a tear in the parchment of a Sefer Torah is also analyzed. Rav rules that a tear spanning two lines may be sewn, but a tear of three lines may not. This is qualified by Rabba Zuti, who distinguished between "new" and "old" parchment, which is defined not by age but by whether or not it was processed with gall. Furthermore, the sewing must be done with sinews (gidin) and not plain thread. A question is left unresolved regarding whether these measurements apply if the tear occurs between columns or between lines. Regarding the writing of a mezuza, Rav Chananel in the name of Rav states that if it is written with two words on a line, it is valid. Rav Nachman explains that it can be written like a shira (song) - for example, two words, then three, then one. When questioned by a braita, he distinguishes between the requirements of a Sefer Torah and a mezuza. The Gemara clarifies that while a mezuza can be written in shira format, it must not be formatted like a "tent" or a "tail" (narrowing or widening). There is a discussion regarding the final words of the mezuza, "al ha'aretz." Should they be placed at the end of the line or at the beginning? The two views reflect different symbolic meanings: one highlights the height of heaven above the earth, while the other highlights the distance between them. Rav Chelbo mentions Rav Huna, who would roll the mezuza scroll from the end to the beginning and made the paragraphs "closed" (setumot). This is challenged by a ruling of Rabbi Meir, who made the paragraph breaks "open" (petuchot).
