About this episode
Today's daf is sponsored by Shira Dishon in loving memory of her son, Eitan Dishon, who was killed in Gaza on the 20th of November. "Today would have been his 22nd birthday. Among his belongings, they found his Gemara, with which he studied daf yomi, stained with his blood. I understood that this was his legacy and began to study daf yomi for the first time. I recently completed Bava Metzia, my first masechet, with Hadran." The Mishna delineates items that need to be distanced from a neighbor's pit or wall. The Gemara delves into each of the sections of the Mishna. What is meant by a launderer's pool? In the first category of items, the Mishna rules that it must be distanced and plastered. Does the Mishna mean "and" or "or"? In comparing our Mishna to a Mishna in Shabbat 4:1 regarding items one cannot use for insulating food where a similar list appears of items that create heat, they notice that stones appear here and not there and sand appears there and not here. Why? Why is it necessary to mention both distancing seeds and a plow? Why do seeds need to be distanced? The Mishna rules that urine must be distanced from another's wall. However, Raba bar bar Hana rules that one can urinate next to another's wall. How can his statement be explained in light of the Mishna? Even though the Gemara suggests an explanation, they reject Raba bar bar Hana's statement in light of a braita. Shmuel ruled that a wafer placed in a window does not block impurities from a dead body from passing through. A contradiction is brought from a Mishna in Ohalot 6:2, but is resolved.
