Talking Talmud

The Gemara moves on to the mishnah''s case of an animal that was missing a liver -- which is surely a treyfa -- but what if an olive's worth remained? That seems to define the animal as a kosher animal. But less than a "kezayit" amount of the liver seems that it would get that treyfa distinction. Also, 4 rulings - listed with a mnemonic. Including the case of creepy crawlies - and the question of them not bleeding, with implications for Shabbat -- all as a parallel to a punctured (or not!) lung. But note throughout here the lack of attack among the sages, despite all the differences of opinion, and with practical implications.

A review of injuries to various body parts and the implications for a kosher shechitah. Note the sages' awareness of the animals' anatomy. After all, they did open these animals up and were able to discern their inner workings. Note also the sages' verbal descriptions of the visual/physical. Also, a deeper dive into the potential perforation of the heart -- and which chamber of the heart was (presumably necessarily) perforated? And, of course, note the big loss that a treyfa discovery would mean. It wasn't a simple thing to render the meat before the shochet into non-kosher food.

An investigation into an acceptance of the stringencies of Rav and the stringencies of Shmuel when it comes to the details of shechitah, including the location of where one begins the process of slaughtering. But taking the stringencies of both sages, instead of following either of them for the full gamut of their respective views, seems incongruous in its inconsistency. Plus, the bat kol (heavenly voice) that establishes halakhah as per Beit Hillel, though it seems a contradiction here -- and also as against the statement that we do not determine practice from a bat kol! Also, what is the "majority" of the trachea? Is it the thickness of the trachea wall or is it the majority of the hollowness of the tube itself? Plus, the case of Yehezkel (Ezekiel), who never personally ate from the meat of an animal that had been called into question, even though it was subsequently declared fine. Also, the decision to offer the prime cut.

Ulla says that there 8 groups of treyfot that were told to Moses at Sinai - that is, the categories. Plus a focus on a punctured gallbladder, among other potential issues, where the animal may actually not die (but isn't that a miraculous event, and therefore not a proof for anything?). Also, a focus on some kind of injury for an animal that might or might not make the animal a treyfa -- with the example of a thorn in the animal's esophagus. And 4 cases that argue against Ulla's positions.

Chapter 3! A focus on the slaughtering of kosher animals -- and what makes an animal kosher (as compared to a treyfa, which is a kosher kind of animal, but some blemish prevents it from being kosher upon shechitah). Which is to say: a new mishnah -- that lists 18 "defects" that make an animal a treyfa in detail - and then because of the animal's status, the shechitah cannot be kosher. Plus, what is the source in the Torah for this concern about a treyfa? That should be obvious - it's an explicit verse, but what about the position that a treyfa has to be an animal that won't live from the defect? That source is provided - Leviticus 11. Also, the Gemara adds another 7 ways an animal could become a treyfa. With a mnemonic to remember them -- and a strong question why they weren't included in the 18.
