Chulin 50

CHULIN 47-50 - sponsored by Dr. Lindsay A. Rosenwald of Lawrence NY, in honor of his father, David ben Aharon ha'Levy Rosenwald of blessed memory.


(a) We determine which Cheilev is Chimtza and which, bar Chimtza, from a statement of Rav Nachman.
Why did Rav Nachman maintain that fat known as d'Ayt'ra must block a hole in the Keivah? So what is bar Chimtza?

(b) How do we know that Rav Nachman is referring to d'Ayt'ra and not to de'Aksh'sa?

(a) What is ...
  1. ... d'Aksh'sa?
  2. ... d'Ayt'ra? What does it mean?
(b) What is the basis of the Machlokes between the B'nei Eretz Yisrael and the B'nei Bavel, according to the first Lashon?

(c) Why then, do even the B'nei Eretz Yisrael agree that de'Aksh'sa is forbidden?

(a) According to the second Lashon, both the B'nei Eretz Yisrael and the B'nei Bavel permit d'Ayt'ra.
Why is that?

(b) And they argue over de'Aksh'sa.
What is the basis of their Machlokes?

(c) Why must Rav Nachman hold like the first Lashon and not like the second?

(d) Rebbi Ami (quoted by Rav Ivya) and Rebbi Yanai were both B'nei Eretz Yisrael.
What did they mean when they said 'Mekamtzin'?

(a) Rav Ivya saw Rebbi Ami actually eating a piece of d'Ayt'ra after some of the fat just above it had been removed.
What did Rebbi Chanina comment, when he saw his Shames hesitate to remove the fat and serve him the d'Ayt'ra?

(b) So what did he instruct him to do?

(a) What does Raban Shimon ben Gamliel in a Beraisa say about a hole in the intestines that is blocked by internal fluid? How does Rav Kahana describe that fluid?

(b) What did Rebbi Zeira the Chaver of Rebbi Aba learn from Rebbi Aba (or Rebbi Aba the son of Rebbi Chiya bar Aba the Chaver of Rebbi Zeira, from Rebbi Zeira)?

(c) He also learned from him that the Halachah is like Rebbi Shimon regarding Avelus.
What distinction does the Tana Kama in the Mishnah in Mo'ed Katan, make between an Avel who arrives at the mourner's house from close by, and one who arrives from far? What is considered 'close by'?

(d) What does he say about an Avel who arrives after three days?

(e) What does Rebbi Shimon say?

(a) What did an anonymous Talmid hope to do if and when he went to Eretz Yisrael?

(b) What did Rebbi Aba b'rei de'Rebbi Chiya bar Aba reply when the Talmid asked him whether it was true that he rules 'Halachah ke'Rebbi Shimon ben Gamliel bi'Tereifos'?

(c) Whether or not, the Halachah is like Rebbi Shimon be'Avel is a Machlokes Amora'im. We ultimately rule like Rebbi Shimon, based on a principle of Shmuel.
What does Shmuel say about Avelus?

(a) Rav Shimi bar Chiya holds 'Makifin bi'Venei Me'ayim'.
What did Rava's son, Rav Mesharshaya do, after his father had compared an intestine with a hole to another hole which they cut beside it after the Shechitah, and found them dissimilar?

(b) On what did he base this?

(c) What did Rava subsequently declare?

(a) Rebbi Yochanan and Rebbi Elazar both hold 'Makifin be'Re'ah'.
To which parts of the lung does this apply?

(b) How does Rava qualify this ruling?

(c) We rule however 'Afilu me'Arugah la'Arugah.
What do we rule regarding 'Makifin ... '?

  1. ... mi'Dakah le'Dakah u'mi'Gasah le'Gasah'?
  2. ... mi'Gasah le'Dakah' or vice-versa?
(d) We interpret 'mi'Dakah le'Gasah' as, from the Una to the Uma.
What else might it mean? On what grounds do we reject that interpretation?
(a) Abaye and Rava hold 'Makifin be'Kaneh'.
What Tereifus are we talking about? With what does one compare the Safek?

(b) How does Rav Papa qualify this ruling?

(c) We do not however, rule like Rav Papa, only 'Makifin me'Chulya le'Chulya u'mi'bar Chulya le'bar Chulya'.
What is 'bar Chulya'?

(d) In which case will we nevertheless concede 'Ein Makifin'?

(a) Ze'iri holds 'Chalcholes she'Nikvah, Kesheirah'.
Why is that? What is Chalcholes?

(b) In explaining this ruling, how does Rebbi Ila'i Amar Rebbi Yochanan differentiate between the place where the Chalcholes cleaves to the thighs and there where it doesn't?

(c) When the Rabbanan cited this ruling to Rava in the name of Rav Nachman, Rava objected to it.
What did he mean when he said 'Lo Tislu bei Buki S'riki'? What are 'Buki S'riki'?

(d) What did Rav Nachman really say?

(e) A K'dei Tefisah of the Chalcholes however, must remain intact. How does Abaye describe a 'K'dei Tefisah'?

Answers to questions



(a) Our Mishnah lists the inner Keres that has been punctured, among the Tereifos.
Rav Yehudah Amar Rav defines this as 'Sanya Divi' (caecus, the large back part of the Keres). Besides possibly meaning 'the hated stuff that drips from there' (because it is the area where the Shochtim cut it open), why is it called by that name?

(b) Rav himself cited the testimony of Rav Nasan bar Shilo in the name of Rebbi Nasan.
Who was Rav Nasan bar Shilo?

(c) Rebbi Yishmael defines the inner Keres as 'Istumchah de'Keres'(the opening of the Keres, which is next to the heart [Aruch]). Rav Asi Amar Rebbi Yochanan explains that it is a narrow part of the Keres, but that he did not know where it was.
What did Rav Nachman bar Yitzchak comment on this?

(d) How does Rav Acha bar Rav Iva in the name of Rav Asi define the narrow part of the Keres?

(a) Rebbi Ya'akov bar Nachmeni Amar Shmuel defines the inner Keres as Makom she'Ein bo Milas, and Ravina Amar G'niva as the last Tefach of the Veshet before the Keres, which we already discussed earlier in the Perek).
What does 'Makom she'Ein bo Milas' mean?

(b) In Eretz Yisrael, they cited Rebbi Yossi b'Rebbi Chanina, who described the inner Keres as the whole Keres.
Then what does the Tana consider the outer Keres?

(c) According to Rabah Rav Huna, the inner Keres is Mifra'ata.
How does Rav Ivya explain that?

(d) What did the Shochtim of Neherda'a used to do?

(a) Rav Ashi asked Ameimar how all the above opinions compared with the 'Mifra'ata'.
Why specifically Ameimar?

(b) Four of the above opinions conform with Rabah bar Rav Huna (since they appear the moment the Shochtim cut open the stomach (whilst the animal is hanging by its hind legs.
Which two opinions disagree with him?

(c) How about the opinion of Rav Asi Amar Rebbi Yochanan ('Makom Tzar Yesh be'Keres'), who was unable to pinpoint where it was?

(d) What is the Halachah ...

  1. ... in this regard?
  2. ... regarding examining for Tereifos? Do we examine for all eighteen of them?
(a) Rebbi Yehudah, in our Mishnah (in connection with 'she'Nikra Keres Chitzonah') commented 'ha'Gedolah Tefach, ha'Ketanah be'Rubah'.
How does Rebbi Binyamin bar Yefes Amar Rebbi Elazar establish ...
  1. ... 'ha'Gedolah Tefach'?
  2. ... 'ha'Ketanah be'Rubah'?
(b) Why does the latter statement appear to be obvious?

(c) How do we therefore establish the Mishnah ('ha'Ketanah be'Rubah') to explain the Chidush?

(a) 'Geniva Amar Rebbi Asi, Nikd'ra ke'Sela Tereifah'.
Why is that, bearing in mind that this is less than a Tefach?

(b) How did Geniva himself explain this to Rebbi Chiya bar Aba, whilst they were standing on the bridge of Neherda'a?

(c) Rav Yosef defined this Shi'ur as three date-pits 'be'Tzipa'.
What did he mean by that? What does 'be'Tzipa' mean?

(d) What alternative Shi'ur did he give?
