Masechet Chullin Daf 43 & 44
Jan. 11th, 2019 08:00 amTwo very technical pages about the specific nature of defects that result in trefas, but I've been a little under the weather, so here are some quick notes.
Daf 43
In proof of Rabbi Yose ben Yehuda's assertion that a puncture in the gallbladder is not a disqualifying trefa, Rabbi Yitzchak ben Yosef cites a verse in Iyov where Iyov complains that he is pouring out gall on the ground. Since Iyov didn't die, this is proof that one can live with a punctured gallbladder.
The Gemara's response is "A nes is different." Iyov didn't live with his wounds because the wound wasn't serious, he lived because the Satan kept him alive to further torment him and let him survive until his salvation. Therefore, we can't learn a halacha about shechita from the case of Iyov.
At the end of the page there's a great little note about pedagogy. The Gemara records Rabbah's teaching about the proper way to inspect the membranes around the gizzard of a bird to see if there's been a puncture. There are two membranes, which have different colors, and a bird is only a trefa if it has been punctured through both membranes. But for technical reasons I don't have the brainpower to go through right now, Rabbah teaches that you must inspect from the inside out.
Then the Gemara records a story of a time when Rabbah was inspecting a bird and he was inspecting from the outside in. His student Abaye saw and objected by pointing out that Rabbah had taught the opposite. So Rabbah followed his student's objection and inspected from the inside, and sure enough, found evidence invalidating the bird. The Gemara says that it wasn't that Rabbah had forgotten his ruling, but that he intentionally pretended not to do it correctly in order to teach Abaye to have the independence to make the ruling on his own.
Daf 44
There are several disagreements between Shmuel and Rav about the exact location of both the highest and lowest points on the esophagus that you can shecht, and the condition of whether a puncture in those highest and lowest points render an animal trefah.
The Gemara records a story where Rava inspected an animal that had been shechted starting near the top of the esophagus and then the majority of the shechita had been lower in the esophagus. It says that Rava ruled it a trefa by taking on both the chumras of Rav and the chumras of Shmuel. In other words, if in a vacuum Rava had only known the halachos of Rav, he would have found the animal kosher, and if he'd only known the halachos of Shmuel, he would have found the animal kosher, but by taking on the most strict parts of each's halacha and combining them, he ruled the animal trefa.
Rabbi Abba heard about this and he issued a ruling saying that Rava was responsible for compensating the owner of the animal for unfairly making the animal a trefa when he shouldn't have.
Mar the son of Ravina cites a baraisa that says that the halacha is always in accordance with Rabbi Hillel, but one may choose to follow Rabbi Shammai... but if one always follows the kulas of Rabbi Hillel and Rabbi Shammai, in order to construct the most lenient Judaism, they are evil, and if they always follow the chumras of Rabbi Hillel and Rabbi Shammai, they are a fool.
From this the Gemara learns that Rava could not have been, as originally supposed, following the chumras of both Rav and Shmuel and it reinterprets the halacha to find that Rava was following the halacha of Rav.
