KERISUS 22 (11 Elul) - Dedicated by Rabbi Mordecai Kornfeld and family l'Iluy Nishmas Rabbi Kornfeld's father, Reb Aharon David ben Mordechai Kornfeld, a model of dedication to Torah and love for his fellow Jew and for all of Hashem's creations. His Yahrzeit is 11 Elul.


1. The Beraisa explains how we conclude which species contain the blood that is forbidden by the Torah.
2. Rav Ada: This (#1) includes the blood of a Koy.
3. The Gemara proceeds to discuss how we derive other laws regarding a Koy.
4. There is a dispute about the blood of a Neveilah.

5. Fish or grasshoppers need not be slaughtered before they are eaten.


1. The Torah mentions a bird and a domesticated animal. We derive that just as these can have light or severe impurity, can be permitted or prohibited, and are a type of meat, the blood of anything which shares these characteristics is prohibited.
2. The Beraisa clearly says that a Koy is a unique creation that is neither a domesticated animal nor an undomesticated one. Even so, this teaching places its blood into the category of blood that is prohibited to be eaten.
3. Its Chelev is forbidden from the verse, "All Chelev." Its Neveilah is forbidden from the verse, "All Neveilah." Its Gid ha'Nasheh is forbidden from the verse, "Kaf ha'Yarech."
4. Beis Hillel: It is Tamei like the Neveilah itself. Beis Shamai: It is not Tamei.
5. They therefore are excluded from the teaching above (#1), since they are not similar to an animal in that they are never prohibited before being slaughtered (since there is no requirement to slaughter them).
