Talking Talmud

More on case of the fetus -- when does the principle of "majority" apply to limbs emerging? Or does it ever? When is it considered as if it was born? What if half of the fetus has emerged, but a majority of a particular limb? A nuanced, and likely boundary-pushing case. Also, what if the fetus were wrapped while it was still internal? Is that a barrier to the sanctity of the first-born? What about its amniotic sac? What about shenanigans by a weasel that removes and replaces the fetus? Also - a new mishnah about whether the fetus is pure or impure, as per the parent, or (as the main view in the mishnah stipulates), the fetus is inherently pure and won't convey impurity. The Gemara probes this rationale. Plus, an important distinction between animals' feet - when they are paws as compared to cloven hooves.

More on a fetus that extends a limb from its mother's womb and brings it back inside. What if that takes place in between the severing of the first "siman" and the second "siman" in slaughtering the mother. Will the progeny of that fetus (after it grows up) need slaughtering, though that animal itself does not require slaughtering? Also, complications of this kind of animal when it comes to exchange (temurah) for another animal that was not born with the same unusual status. Plus, the first-born (bekhor) - when it's the fetus in these kinds of cases, where it might even be dismembered to help it out of the womb (and then it isn't a bekhor after all, unless the majority of it came out whole).

Chapter 4! With a new mishnah. On the case of a female animal that is slaughtered with a fetus in her womb, whether it is discovered after slaughtering or in the case that she is slaughtered during the birth. If the fetus is inside the mother at the time of the slaughtering of the mother, the fetus is considered slaughtered as well. Also, one view on a limb from the fetus that emerges from the mother's body is not kosher. And another challenges that. Plus, meat "outside the field" cannot be eaten, in contrast to the fetus that remains in the bounds of the mother.

Rav Huna says not to pour beer in the night with a filter, lest a creepy crawlie comes outside of the filter and into the beer, which would be a problem to drink. How does one distinguish between that which is just the normal manner of growth, which would be acceptable, and when there's a problem of unusual bug activity. Also, an investigation into the question of worms - in that they come from outside of the animal, as compared to internal "spontaneous generation." What about larvae? And what about fish larvae? Also, again, "according to its kind" - for a worm and a scorpion and a beetle and a centipede. That is, those creepy crawlies that are not considered kosher. Plus, the Leviathan, which doesn't reproduce, is a kosher fish -- and it will be the feast for the righteous in the future.

Fish that have scales for part of their lives -- are likely to be kosher. But fish that have fins and no scales are not kosher. But if scales are all that matters, why doesn't the Torah just say scales? Why mention fins at all? The Gemara gives several answers. Also, the Gemara focuses on the language of the permitted and prohibited -- both of which forms are stated. Plus, eating that which grow in water is permitted, say, pits and ditches, but what about vessels? How did these creatures emerge from the water?!
