honor of his father, David ben Aharon ha'Levy Rosenwald of blessed memory.
1) CHECKING A "DERUSAH" (cont.)
(a) (Rav Bibi bar Abaye): A puncture of any size in the
Veshet is Tereifah; the same applies to redness of any
size on account of venom.
2) OTHER "TEREIFOS"
(b) Question (Rav Bibi): In the Kaneh, a hole the size of an
Isar (a coin) is Tereifah - how much redness is Tereifah?
(c) Answer (Rav Bibi): Redness of any size is Tereifah.
1. This is because the venom burns.
(d) (R. Yitzchak bar Shmuel bar Marsa): One must check around
innards of a Derusah.
(e) (Rav Nachman): I swear, Rav requires from the Kafa until
1. Question: To which Kafa does he refer?
(f) (R. Yochanan and Reish Lakish): One must check the
i. Suggestion: He refers to the shoulder blade of
2. Answer: Rather, he refers to the base of the brain.
ii. Rejection: If so, he agrees with R. Yitzchak
(there would be no need to swear!)
(g) (R. Chiya bar Yosef): Rav requires from the Kafa until
1. Reish Lakish: Who is this 'Rav'?
2. R. Yochanan: He learned from Rebbi and R. Chiya! He
sat before Rebbi, whereas I had to stand; he is
great in Torah and piety.
(a) (Reish Lakish citing Rav): If in a slaughtered animal the
Kaneh was found uprooted, it is Kosher - had it been
uprooted from before slaughter, the Kaneh could not have
3) WOUNDS THAT DO NOT MAKE AN ANIMAL TEREIFAH
(b) (R. Yochanan): One makes another cut in the Kaneh (now,
after slaughter) - if it resembles the first cut, we
assume that the Kaneh was already uprooted when the first
cut (the slaughter) was done.
(c) (Mishnah): This is the rule...
(d) Question: What does this come to include?
(e) Answer: It includes the seven teachings of the Amora'im
(f) Certain hunters would kill animals by hitting them on the
(g) Question: Does this make an animal Tereifah?
(h) Answer (R. Yehudah ben Beseira): No - we cannot add to
the Tereifos that Chachamim listed.
(i) Certain hunters would kill animals by hitting them on the
(j) Question: Does this make an animal Tereifah?
(k) Answer (R. Aba): No - we cannot add to the Tereifos that
(l) Question: But we see, the animals die from this!
(m) Answer: We have a tradition - if a salve was applied,
they could live.
(a) (Mishnah): The following animals are Kosher:
1. The Kaneh was punctured or split.
(b) R. Meir says, if the skin was removed, it is Kosher;
i. Question: How much can be missing (and it is
2. Part of the skull is lacking, but the membrane is
ii. Answer (R. Shimon ben Gamliel): Up to the size
of an Isar may be missing.
3. The heart was punctured, but the hole does not reach
an inner chamber;
4. The backbone was broken, but the spinal cord was not
5. The liver was removed, but a k'Zayis remains;
6. The wall between the Masas and Beis ha'Kosos
(intermediate stomachs) was punctured;
7. The spleen or kidneys were removed;
8. The lower jaw was removed;
9. The lung dried by natural causes;
(c) Chachamim say, it is Tereifah.
(d) (Gemara - R. Yochanan): The Mishnah (42A) 'These make an
animal Tereifah' is precise (nothing is omitted.)
(e) (Reish Lakish): (Our Mishnah) 'An animal with any of
these defects is Kosher' is precise.
(f) They argue about Rav Masna's law.
1. (Rav Masna): If the hip bone was dislocated, it is
2. According to R. Yochanan, 'this is the rule' (in the
Mishnah 42A) includes cases similar to the Mishnah
which are also Tereifah;
4) A PART MISSING IN THE "KANEH"
(g) (Rav Masna): If the hip bone was dislocated, it is
i. The Tana was afraid that people will think that
Rav Masna's case is also included (since
dislocation is like something missing) -
therefore, he taught '*These* are Tereifos', to
exclude Rav Masna's case.
3. According to Reish Lakish, 'this is the rule' (42A)
includes similar cases which are also Tereifah;
i. The Tana saw that Rav Masna's case, even though
it is Tereifah, is not included (since
dislocation is not a puncture, cut, or missing)
- therefore, he taught (here) '*These* are
Kosher', to exclude Rav Masna's case.
1. (Rava): It is Kosher - but if the attached sinew is
cut, it is Tereifah.
2. The law is, even if the sinew is cut it is Kosher,
unless it is corroded.
(a) (Mishnah) Question: How much can be missing...?
5) DOES 'UNTIL' MEAN 'INCLUDING'?
(b) (Ze'iri): The Isar is the same size like the Dinar of
Kordina'ah, and like small Peshiti of Pumbadisa.
(c) R. Chana (a moneychanger) related that Bar Nafcha wanted
to see the Kordina'ah Dinar; Bar Nafcha did not let R.
Chana stand up for him.
1. Bar Nafcha: Workers are not allowed to (stop working
to) stand for Chachamim.
2. Question (Mishnah): (When people come bearing
Bikurim), all workers stand for them, greet them and
3. Answer (R. Yochanan): Yes, workers stand for people
bearing Bikurim, but they don't stand for Chachamim.
4. (R. Yosi bar Avin): This shows how great is a
Mitzvah in its time - we honor one engaged in a
Mitzvah more than we honor Chachamim!
5. Rejection: Perhaps letter of the law, we do not -
this was a special enactment regarding Bikurim, lest
people will not bother to bring Bikurim again
(because they received no encouragement.)
(a) (Rav Nachman): When Chachamim required (the size of) a
Sela (Rashi - a skull missing a Sela is Tereifah; R. Tam
- if all the skin was removed but a Sela remains, it is
Kosher; Tosfos - if there is a hole the size of a Sela in
the outer Keres, it is Tereifah), exactly a Sela is like
more than a Sela;
1. Our Mishnah says that a hole in the Kaneh 'until the
size of an Isar' is Kosher - exactly an Isar is like
more than an Isar.
2. Inference: Rav Nachman holds that the language 'Ad
(until)' connotes 'until but not including'.
3. Question (Rava - Mishnah): If a rope sticks out of a
bed, until five Tefachim, it is Tahor (i.e. if it
becomes Tamei, the bed does not become Tamei with it
- this is because it is too short to be useful.)
i. Suggestion: This means until and including
4. Answer: No, it means until but not including five.
5. Question (Rava - Mishnah): From five Tefachim until
10, it is Tamei.
i. Suggestion: This means until and including 10
6. Answer: No, it means until but not including 10.
