(a)Another Mishnah in Keilim, discussing the minimum Shi'ur of small earthenware vessels that are subject to Tum'ah, mentions 'Hein (the complete vessels) ve'Karkeroseihen ve'Dafnoseihen'. What is the meaning of ...

1. ...Karkeroseihen?

2. ... Dafnoseihen?

(b)Under which condition are they still subject to Tum'ah?

(c)What is the Shi'ur Tum'ah (for which they must till be useful [how much must they contain]?), assuming they originally held ...

1. ... up to a Log?

2. ... between a Log and a Sa'ah?

3. ... between one and two Sa'ah?

(d)How will Rav Nachman explain 'Ad' and 've'Ad' in all these cases?

(e)But how will he explain the Beraisa 'Log ki'Lematah, Sa'ah ki'Lematah, Sa'sayim ki'Lematah'?

1)

(a)Another Mishnah in Keilim, discussing the minimum Shi'ur of small earthenware vessels that are subject to Tum'ah, mentions 'Hein (the complete vessels) ...

1. ... ve'Karkeroseihen' - their bases (should they break)

2. ... ve'Dafnoseihen' - or one of their walls ...

(b)... which are still subject to Tum'ah - provided they are able to stand without being supported.

(c)The Shi'ur Tum'ah, assuming they originally held ...

1. ... up to a Log is - if they can still contain sufficient oil to anoint a small child.

2. ... between a Log and a Sa'ah is - if they can hold a Revi'is of liquid.

3. ... between one and two Sa'ah is - if they can hold half a Log of liquid.

(d)In all these cases, Rav Nachman will explain 'Ad' and 've'Ad' - as being exclusive (in which case, a vessel that holds a Log, for example, will only be subject to Tum'ah if it can still hold a Revi'is of liquid).

(e)He will explain the Beraisa 'Log ki'Lematah, Sa'ah ki'Lematah, Sa'sayim ki'Lematah' - as being a Chumra (mi'de'Rabbanan). Note, that we will now have to concede that Rav Nachman's ruling of 'ad ve'Lo ad bi'Chelal' regarding a ke'Isar by T'reifos, is specifically le'Chumra, forcing us to retract from some of our interpretations of the Mishnahs in Keilim.

2)

(a)This answer is based on a statement by Rebbi Avahu Amar Rebbi Yochanan 'Kol Shi'urei Chachamim Lehachmir'. The one exception is ki'Geris shel Kesamim. What does that mean?

(b)Why do the Chachamim go Lehakel specifically there?

(c)In connection with the earlier Mishnah in Keilim, what distinction does the Beraisa draw between 'Chamishah' and 'Asarah'?

(d)What do we prove from there?

2)

(a)This answer is based on a statement by Rebbi Avahu Amar Rebbi Yochanan 'Kol Shi'urei Chachamim Lehachmir'. The one exception is ki'Geris shel Kesamim - meaning a bloodstain the size of a bean (regarding Safek Nidus) on the garment of a woman, which is Tahor if it is exactly a ki'Geris.

(b)The Chachamim go Lehakel specifically there - because the entire Din of bloodstains (that render a woman Tamei) is mi'de'Rabbanan.

(c)In connection with the earlier Mishnah in Keilim, the Beraisa rules - 'Chamishah ki'Leme'elah, ve'Asarah ki'Lematah' (Le'chumra at both ends) ...

(d)... a proof that - our interpretation of the second Mishnah in Keilim is correct.

3)

(a)We learned in our Mishnah 'Nital ha'Techol, Kesheirah'. What does Rav Avira in the name of Rava say regarding Nikav ha'Techol?

(b)Why the difference?

3)

(a)We learned in our Mishnah 'Nital ha'Techol, Kesheirah'. Rav Avira in the name of Rava confines this ruling to Nital. In a case of Nikav ha'Techol - he declares the animal T'reifah (another one of the Shev Shema'atsa) ...

(b)... because the pain the animal suffers causes the wound to intensify, until it results in its death.

4)

(a)The Mishnah in the fourth Perek permits cutting off a piece of fetus from inside the animal's womb and eating it after the mother has been Shechted. What does the Tana say about doing the same regarding the spleen or the kidneys?

(b)What do we try to extrapolate from there that poses a Kashya on Rav Avira?

(c)If, as we answer, the entire animal is forbidden too, why does the Tana forbid specifically the spleen or the kidney?

(d)What alternative answer do we give to reconcile Rav Avira with this Mishnah, even assuming that the animal is indeed not T'reifah?

4)

(a)The Mishnah in the fourth Perek permits cutting off a piece of fetus from inside the animal's womb and eating it after the mother has been Shechted - though the Tana forbids doing the same regarding the spleen or the kidneys (as we will explain there).

(b)We try to extrapolate from there that - the animal itself is permitted, a Kashya on Rav Avira (since an animal with a piece of spleen cut off is akin to having a hole in it).

(c)And we answer that even though the entire animal is forbidden too, the Tana mentions specifically the spleen or the kidneys - in order to balance the Reisha, to teach us that although a piece of the fetus is permitted, a piece of the spleen or the kidneys is not.

(d)Alternatively, we reconcile Rav Avira with this Mishnah, even assuming that the animal is indeed not a T'reifah - by differentiating between a hole in the spleen, which is T'reifah) and a piece that is cut off (which is not).

5)

(a)What does Rachish bar Papa in the name of Rav say about one kidney that is full of pus?

(b)How did they qualify this ruling in Eretz Yisrael?

(c)How do we describe the location of the groove?

5)

(a)Rachish bar Papa in the name of Rav rules that one kidney that is full of pus - renders the animal T'reifah.

(b)They qualified this ruling in Eretz Yisrael - by restricting it to where the wound as reached the groove (where the nerves fuse) in the middle of the kidney ...

(c)... which we describe as - the location of the white area underneath the loins.

6)

(a)What did all the Poskim of T'reifos in Eretz Yisrael tell Rebbi Nechunya (Halachah-wise), regarding Rachish bar Papa and Rav Avira's previous rulings?

(b)In which case did they nonetheless agree with Rav Avira?

(c)How did they qualify this ruling? When will even a hole in the thick end of the spleen not render the animal T'reifah?

6)

(a)All the Poskim of T'reifos in Eretz Yisrael told Rebbi Nechunya that - although the Halachah is like Rachish bar Papa (regarding pus in the kidney), it is not like Rav Avira (regarding a hole in the spleen).

(b)They nonetheless agreed with Rav Avira - in a case where the hole is located in the thick part of the spleen (that the animal is a T'reifah).

(c)They qualified this ruling however - by confining it to where the hole pierced to within the thickness of a golden Dinar of the spleen's wall. Otherwise, the animal is Kasher.

55b----------------------------------------55b

7)

(a)From where did the n'nei Eretz Yisrael learn the principle Kol ha'Posel be'Rei'ah, Kasher be'Kulya?

(b)What Kal va'Chomer do we initially extrapolate from their ruling?

(c)How does Rebbi Tanchuma query this from the Din of ...

1. ... pus in both cases?

2. ... pure water that is Kasher even by a Kulya (see Tosfos DH 've'Harei')?

(d)So what does Rav Ashi conclude?

7)

(a)The b'nei Eretz Yisrael learn the principle Kol ha'Posel be'Rei'ah, Kasher be'Kulya - from the Din of a hole, which is T'reifah in the lung, but Kasher in the kidneys.

(b)Initially, we extrapolate from their ruling that - whatever is Kasher in the case of a lung, is certainly Kasher in that of a kidney.

(c)Rebbi Tanchuma queries this however, from the Din of ...

1. ... pus - which is Kasher in the lungs but T'reifah in the kidneys.

2. ... pure water that is Kasher even by a Kulya - even though it is caused by a wound, just like pus (yet it does not render the animal T'reifah, like pus does), a proof that one cannot compare one T'reifus to another (Tosfos DH 've'Harei').

(d)Rav Ashi therefore concludes that - one cannot in fact, learn one case from another in T'reifos (just as we sometimes find that something is Kasher when it is cut from one place and T'reifah when it is cut from another, even though it may appear to be illogical, as we learned earlier), and that consequently, it is also feasible for something to be Kasher in the lungs and T'reifah in the kidneys.

8)

(a)In which case will even ...

1. ... pure water in the kidney render the animal T'reifah?

2. ... clear water render it T'reifah, too?

(b)If the kidney of a small animal which has shrunk to the size of a bean renders the animal T'reifah, to what size must the kidney of a large animal shrink, to render it T'reifah?

(c)We learned in our Mishnah 'Nitlah Lechi ha'Tachton, Kesheirah'. On what condition will the Tana agree that the animal whose lower jaw is dislocated, is T'reifah?

(d)If the Eim of the animal is the womb, what is the Tarpachas (mentioned later in the Perek) and the Shalfuchis (mentioned earlier)?

8)

(a)Even ...

1. ... pure water in the kidney will render the animal T'reifah - if it is not clear.

2. ... clear water will render it T'reifah - if it smells putrid.

(b)The kidney of a small animal which shrunk to the size of a bean renders the animal T'reifah, the kidney of a large animal - must shrink to the size of a medium-size grape to render it T'reifah.

(c)We learned in our Mishnah 'Nitlah Lechi ha'Tachton, Kesheirah'. The Tana will agree however, that the animal with a dislocated lower- jaw is T'reifah - if one is unable to feed it.

(d)The Eim of the animal is the womb - and so is the Tarpachas (mentioned later in the Perek) and the Shalfuchis (mentioned earlier).

9)

(a)We learned in our Mishnah 'Charusah bi'Yedei Shamayim, Kesheirah'. What does bi'Yedei Shamayim mean?

(b)In which case will a shriveled lung render the animal T'reifah?

(c)Rebbi Shimon ben Elazar adds 'Af bi'Yedei Kol ha'Beriyos'. What are the two possible interpretations of Rebbi Shimon ben Elazar's statement?

9)

(a)We learned in our Mishnah 'Charusah bi'Yedei Shamayim, Kesheirah'. bi'Yedei Shamayim means - via the elements (such as thunder or hail).

(b)A shriveled lung will render the animal T'reifah - if it was frightened by a noise made by a human being.

(c)Rebbi Shimon ben Elazar adds 'Af bi'Yedei Kol ha'Beriyos', which comes - either to add to the leniency of the Charusah bi'Yedei Shamayim, or to the stringency of Charusah bi'Yedei Adam (we are not, at first sure, which).

10)

(a)We resolve the Safek from another Beraisa. What does Rebbi Shimon ben Elazar comment on the Tana Kama there, who says 'Charusah bi'Yedei Adam, T'reifah'?

(b)Why is Rebbi Shimon ben Elazar's statement less ambiguous there than it is in the previous Beraisa?

(c)When Rabah bar bar Chanah found some rams in the desert whose lungs had shriveled, the Talmidim in the Beis Hamedrash advised him to place them in water and leave them for twenty-four hours to see what would happen. How would he then discover whether they had shriveled bi'Yedei Shamayim (and were Kasher) or bi'Yedei Adam (and were T'reifah)?

(d)In which two ways did the test differ in the summer from in the winter?

10)

(a)We resolve the Safek from another Beraisa, where the Tana Kama states 'Charusah bi'Yedei Adam, T'reifah', and Rebbi Shimon ben Elazar comments 'Af bi'Yedei Kol ha'Beriyos'.

(b)Rebbi Shimon ben Elazar's statement is less ambiguous there than it is in the previous Beraisa - because there is only one opinion to which it can refer.

(c)When Rabah bar bar Chanah found some rams in the desert whose lungs had shriveled, the Talmidim in the Beis h'Midrash advised him to place them in water and leave them for twenty-four hours to see what would happen. He would then discover whether they had shriveled bi'Yedei Shamayim (and were Kasher) - if they re-inflated, or bi'Yedei Adam (and were T'reifah) - if they did not.

(d)The test differed in the summer from in the winter - inasmuch as in the summer, he used a bowl of white earthenware and fill it with cold water; whereas in the winter, it was a bowl of black earthenware which he was filled with warm water.

11)

(a)In a Beraisa which cites the Machlokes between Rebbi Meir (Kasher) and the Chachamim (T'reifah) over a Geludah, what do Elazar Safra and Yochanan ben Gudgoda testify?

(b)What does Rebbi Shimon ben Elazar say about Rebbi Meir?

(c)In another Beraisa, Rebbi Oshaya B'no shel Rebbi Yehudah ha'Basam (the spice-seller) testified before Rebbi Akiva that a Geludah is Kasher only as long as a Sela remains intact. What did Rebbi Shimon ben Elazar comment there about the Machlokes between Rebbi Meir and the Chachamim?

(d)How does Rav Nachman bar Yitzchak reconcile this with Rebbi Shimon ben Elazar's own previous statement that Rebbi Meir retracted?

11)

(a)In a Beraisa which cites the Machlokes between Rebbi Meir (Kasher) and the Chachamim (T'reifah) over a Geludah, Elazar Safra and Yochanan ben Gudgoda testified that - a Geludah is T'reifah.

(b)Rebbi Shimon ben Elazar stated that - Rebbi Meir retracted from his original view.

(c)In another Beraisa, Rebbi Oshaya B'no shel Rebbi Yehudah ha'Basam (the spice-seller) testified before Rebbi Akiva that a Geludah is Kasher only as long as a Sela remains intact. Rebbi Shimon ben Elazar commented there that - Rebbi Meir and the Chachamim do not argue that a Geludah is T'reifah.

(d)Rav Nachman bar Yitzchak reconciles this with Rebbi Shimon ben Elazar's own previous statement that Rebbi Meir retracted - by interpreting 'do not argue' to mean that Rebbi Meir did not continue to argue.

12)

(a)They asked where the ke'Sela of skin has to remain for a Geludah to be Kasher. What did Rav Yehudah Amar Rav reply?

(b)This might mean that all that is required is the total volume of a Sela coin, even though it entails no more than a thin strip of skin all the way along the Shedrah. What else might it mean?

(c)We resolve the Safek from a statement by Rebbi Nehorai in the name of Shmuel. What did he say?

(d)Rabah bar bar Chanah and Rebbi Elazar ben Antignus in the name of Rebbi Elazar b'Rebbi Yanai disagree with Rav Yehudah Amar Shmuel. What does Rabah bar bar Chanah mean when he says 'Roshei Perakim'?

(e)According to Rebbi Elazar ben Antignus in the name of Rebbi Elazar b'Rebbi Yanai, the animal will not be a Geludah if there is a ke'Sela of skin on one specific spot on its body. Which spot?

12)

(a)They asked where the ke'Sela of skin has to remain for a Geludah to be Kasher, to which Rav Yehudah Amar Rav replied - along the entire surface of the spine.

(b)This means, either that all that is required is the total volume of a Sela coin, even though it entails no more than a thin strip of skin all the way along the Shedrah - or the width of a Sela all along the spinal cord.

(c)We resolve this Safek from a statement by Rebbi Nehorai in the name of Shmuel, who says - 'ke'Rochav Sela al-P'nei Kol ha'Shedrah'.

(d)Rabah bar bar Chanah and Rebbi Elazar ben Antignus in the name of Rebbi Elazar b'Rebbi Yanai disagree with Rav Yehudah Amar Shmuel. When Rabah bar bar Chanah says 'Roshei Perakim', he means that - the volume of a Sela must remain intact by each and every joint of the vertebrae, of the bones and of the thighs.

(e)According to Rebbi Elazar ben Antignus in the name of Rebbi Elazar b'Rebbi Yanai, the animal will not be a Geludah if there is a ke'Sela of skin - on the navel.

13)

(a)What She'eilah did Rebbi Yanai b'Rebbi Yishmael ask that is common to all three opinions regarding how much skin needs to remain on a Geludah for the animal to be Kasher?

(b)What is the outcome of the She'eilah?

(c)Rav is more lenient than all the above opinions. According to him, a ke'Sela anywhere will render the animal Kasher, except for the skin of the Beis ha'Perasos. What is the Beis ha'Perasos?

(d)Why will it not save a Geludah?

(e)Rebbi Yochanan is more lenient still. What does *he* say?

13)

(a)Rebbi Yanai b'Rebbi Yishmael asked what the Din will be - if all the skin remains except for three areas required by Shmuel, Rabah bar bar Chanah and Rebbi Elazar b'Rebbi Yanai, respectively.

(b)The outcome of the She'eilah is - Teiku.

(c)According to Rav, a ke'Sela anywhere will render the animal Kasher, except for the skin of the Beis ha'Perasos - which is the skin below the knee, which he does consider flesh ...

(d)...on account of its softness.

(e)Rebbi Yochanan is more lenient still - because he includes the skin of the Beis ha'Perasos, too.

14)

(a)When Rebbi Yochanan said this to Rebbi Asi, the latter queried him from a Mishnah in the ninth Perek. What does the Tana there say about the skin of Beis ha'Perasos, that poses a Kashya on Rebbi Yochanan?

(b)Why was Rebbi Yochanan not impressed by the Kashya?

(c)Rebbi Yochanan's answer is based on a Beraisa, which discusses someone who Shechts an Olah with the intention of burning the skin under the fat-tail either in the wrong place or at the wrong time. What is the Din if someone Shechts an Olah with the intention of burning some of the flesh...

1. ... in the wrong place and then eats it?

2. ... at the wrong time, and then eats it (even within the official time-frame)?

(d)And what will be the Din in the equivalent case, but where he intends to burn some of the skin at the wrong time, and then eats it?

14)

(a)When Rebbi Yochanan said this to Rebbi Asi, the latter queried him from a Mishnah in ythe nninth Perek - where the Tana lists the skin of Beis ha'Perasos among those skins that have the Din of Basar (regarding Tum'as Ochlin), a Kashya on Rebbi Yochanan.

(b)Rebbi Yochanan was not impressed by the Kashya however - because he considers the Mishnah in question the opinion of a Yachid (Rebbi Shimon, as we will now see [see also Tosfos DH 'be'Lashon Yachid']).

(c)Rebbi Yochanan's answer is based on a Beraisa, which discusses someone who Shechts an Olah with the intention of burning the skin under the fat-tail either in the wrong place or at the wrong time. If someone Shechts an Olah with the intention of burning some of the flesh...

1. ... in the wrong place and then eats it - although the Olah is Pasul, it is not Pigul, in which case he is not Chayav Kareis.

2. ... at the wrong time, and then eats it (even within the official time-frame) - it is Pigul and he is Chayav Kareis.

(d)In the equivalent case, but where he intends to burn some of the skin at the wrong time - it is not even Pigul, because skin is not considered Basar, and he is not Chayav for eating it.

15)

(a)What does the Tana Kama now say about a case where someone Shechts a Korban with the intention of burning the skin under the fat-tail at the wrong time and then eats it?

(b)Besides the skin of the head of a tender calf, what does Rebbi Shimon ben Yehudah Ish K'far Ikus in the name of Rebbi Shimon, add to the skin under the fat-tail ...

1. ... specifically?

2. ... by inference from 'Kol she'Manu Chachamim gabei Tum'ah Eilu she'Oroseihen ki'Besaran'?

(c)Why do we not also include a Sh'lil (a fetus)?

(d)What has Rebbi now proved from this Beraisa?

15)

(a)The Tana Kama rules that in a case where someone Shechts a Korban with the intention of burning the skin under the fat-tail in the wrong time and then eats it - he is Chayav Kareis, because the skin under the fat-tail is soft, and is considered Basar.

(b)Besides the skin of the head of a tender calf, Rebbi Shimon ben Yehudah Ish K'far Ikus in the name of Rebbi Shimon, adds to the skin under the fat-tail ...

1. ... specifically - the skin of Beis ha'Perasos.

2. ... by inference from 'Kol she'Manu Chachamim Gabei Tum'ah Eilu she'Oroseihen ki'Besaran' - the skin of the womb of a female animal.

(c)We do not also include a Sh'lil (a fetus) - because Sh'lil is not applicable by an Olah, which is a male animal. Note, that in that case, neither is Or Beis ha'Boshes (see Maharam Shif and Tosfos DH 'Lehavi').

(d)Rebbi has now proved from this Beraisa that - it is only Rebbi who considers the skin of the Beis ha'Perasos Basar, but not the Rabbanan.
