BECHOROS 7 (24 Cheshvan) - dedicated by Dr. Moshe and Rivkie Snow in memory of Rivkie's father, the Manostrishtcher Rebbi, Hagaon Rav Yitzchak Yoel ben Harav Gedaliah Aharon Rabinowitz Ztz"l, Rav of Kehilas Nachalas Yehoshua in Canarsie, NY. A personification of the Torah scholar of old, the Ukranian-born Rebbi lived most of his life in the United States where his warm ways changed many lives.


1. Rebbi Shimon says that most of the body and the head of a firstborn animal must be similar to the species of its mother in order for it to be obligated in Bechor (in a minimal fashion).
2. The Gemara discusses whether Rebbi Shimon says that most of the body and the head of an animal that looks like a non-Kosher animal (i.e. a camel) must be similar to the species of its mother (i.e. cow) in order for it to be considered Kosher.
3. Rebbi Yehoshua ben Levi: There are three combinations of categories of animals that cannot bear offspring together.
4. There is an argument in the Gemara about whether a Kosher animal born to a Tereifah mother and healthy father may be brought as a Korban.
5. One may not drink the urine of a donkey, or of any other non-Kosher animal.
6. Rebbi Yakov derives from a verse that we are allowed to eat only bee honey.
7. The Mishnah discusses eating fish swallowed by other fish.
8. Some Amora'im explain that the Mishnah is referring to a case in which we saw the Kosher fish being swallowed by the non-Kosher fish, and we know that it is not offspring of the non-Kosher fish due to how it was found in the non-Kosher fish.
9. Rav Ashi says that one is allowed to eat any Kosher fish found in a non-Kosher fish.
10. The Beraisa states many rules that apply to various living beings.


1. This is unlike the Tana Kama, who merely requires the animal to have some similarities to the species of its mother.
2. The Gemara concludes that Rebbi Shimon indeed requires the head and most of the body to look like the species of the mother in order for it to be considered Kosher.
3. They are: a Kosher animal with a non-Kosher animal, a Behemah Gasah with a Behemah Dakah, and a Behemah with a Chayah.
4. Rebbi Eliezer says that it may not be brought as a Korban, since he understands that Zeh v'Zeh Gorem is forbidden. Rebbi Yehoshua says it may be brought as a Korban, since he maintains that Zeh v'Zeh Gorem is permitted.
5. This is as the Mishnah (5b) states, that whatever comes out of a non-Kosher animal is considered non-Kosher.
6. Rebbi Yakov understands that the verse, "But this you may eat from all Sheretz ha'Of," includes bee honey as Kosher, as opposed to honey from other non-Kosher Sheratzim that is non-Kosher. The Gemara quotes an opinion that other honey, such as that from certain grasshoppers, is permitted.
7. One may eat a Kosher fish that was swallowed by a non-Kosher fish, but he may not eat a non-Kosher fish swallowed by a Kosher fish.
8. For example, Rav Sheshes says it was found in the area where the non-Kosher fish excretes waste, indicating it is not the offspring of the non-Kosher fish. Rav Papa similarly says that it was found in its throat.
9. Rav Ashi reasons that since most fish have offspring that are similar to them, one is allowed to eat Kosher fish found in non-Kosher fish even if he did not see that the Kosher fish was swallowed by the non-Kosher fish.
10. For example, it says that a non-Kosher fish has babies, while a Kosher fish lays eggs. Any being that gives birth to babies nurses, while beings that lay eggs gather food for their young (but do not nurse, with the exception being an Atalef).
