Talking Talmud

If a neckbone of person were person - in parallel to the bird's neck the other day - the question arises as to whether or when the status of impurity kicks in. With the example of Eli the high priest of the Book of Samuel (I), who fell, whose neckbone broke, and who died, "because he was old." Also, a beraita on the melikah of a bird burnt-offering. And how it's different from a burnt-offering bird's melikah. With physical directions, in its intricacy.

Diving into the details of melikah -- specifically the process, and the debated points of that process. Also, some ways in which melikah is different from shechitah, the slaughtering of the animals that are not birds. Also, on what happens if the bird's neckbone breaks in such a way that it cuts the flesh as well, then there's no shechitah - and the animal is a "neveilah" - with death that didn't happen via shechitah. As compared to a tereifah.

A descriptive daf... of details of slaughtering. That is, cutting the trachea in ways that are not obviously kosher, but may be so, and that leads to disputes over how and when which cutting took priority to determine the kashrut of the shechitah. Plus, a description of the sages sitting in rows and learning, considering different permutations where the shechitah is kosher or not. Also, what if the person doing the slaughtering is not Jewish? When is there leeway to see that shechitah as kosher? And all the implications for melikah...

In the case of a person who doesn't send his knife to be approved by a Torah scholar, the shochet should be ostracized or, alternatively, removed from his position, depending on whose opinion or the specific circumstances. And "removing from his position" doesn't stop there - he can't sell his meat as kosher, and it is to be wiped with feces so that it can't be sold to non-Jews either. Also: 2 new mishnayot - 1: On attempting shechitah with a rounded sickle with rounded serration - it's a machloket whether that's permitted. 2. On where precisely to slaughter on the trachea. Plus, if the slaughtering were done in a lower piece of cartilage, then it's not kosher according to Rav or Shmuel, but then someone who should be their follower (or either) ate from that shechitah. Note the distinction between the leniency in the land of Israel compared to the stringency in Babylonia, and how one needed to navigate the various practices.

On the phrasing of everyone can slaughter, everywhere and when, and with anything that can do proper slaughter (for example, a shard of glass). The Gemara shifts the focus from the animal to the person during the slaughtering - to include the Samaritan and a sinner, for example. Plus, Shmuel's father sent a knife and a question about it to the sages in the land of Israel to determine the permissibility of using it for shechitah. Also, the concerns about notched knives and how we know to check such a knife from the Torah. Plus, the different ways of checking the knife, including the sage who tested it on his own tongue.
