Avodah Zarah 39

התם ידיע ממשו הכא לא ידיע ממשן

The Gemara explains: There, the substance of the wine is a recognizable component of the fish stew; here, its substance is not a recognizable component of the pickled vegetables.

וטרית טרופה וציר שאין בה דגה וכו׳ מאי חילק אמר רב נחמן בר אבא אמר רב זו סולתנית ומפני מה אסורה מפני שערבונה עולה עמה

§ The mishna teaches: And minced tarit fish, and brine that does not have a kilbit fish floating in it, and ḥilak are all prohibited. The Gemara asks: What is ḥilak? Rav Naḥman bar Abba says that Rav says: This is sultanit, a type of small fish that is generally caught before its scales have developed. And for what reason is it prohibited? It is because its size causes it to be intermingled with other fish, and as a result sultanit rises out of the water with non-kosher fish when it is caught.

תנו רבנן אין לו עכשיו ועתיד לגדל לאחר זמן כגון הסולתנית והעפיץ הרי זה מותר יש לו עכשיו ועתיד להשיר בשעה שעולה מן הים כגון אקונס ואפונס כטספטייס ואכספטייס ואוטנס מותר

The Sages taught: If a fish does not currently possess scales but will grow them after a period of time, such as the sultanit and afiyatz fish, it is permitted. Likewise, if it has scales now but will shed them when it is caught and rises from the sea, such as akunas and afuna, ketasfatiyas and akhsaftiyas and otanas fish, it is permitted.

אכריז רבי אבהו בקיסרי קירבי דגים ועוברן ניקחין מכל אדם חזקתן אינן באים אלא מפלוסא ואספמיא כי הא דאמר אביי האי צחנתא דבב נהרא שריא

Rabbi Abbahu announced in Caesarea: Fish entrails and their eggs may be purchased from any person, as the presumption with regard to them is that they come only from Pelusium [Pilusa] and Spain [Aspamya], and non-kosher fish are not found in those areas. This is similar to that which Abaye says: These small fish [tzaḥanta] of the Bav River are permitted, as non-kosher fish are not found in that river.

מאי טעמא אילימא משום דרדיפי מיא והאי דג טמא כיון דלית ליה חוט השדרה בדוכתא דרדיפי מיא לא מצי קאי והא קא חזינן דקאי

The Gemara asks: What is the reason that Abaye unequivocally permitted eating these fish and was not concerned about the potential presence of non-kosher fish among them? If we say that it is due to the fact that the water flows rapidly, and these non-kosher fish, since they do not have a spinal cord, are not able to exist in a place where the water flows rapidly, as the current carries the non-kosher fish out of the Bav River, and consequently all the remaining fish are kosher, that is not the case, since we see that non-kosher fish exist in rivers with strong currents.

אלא משום דמליחי מיא והאי דג טמא כיון דלית ליה קלפי בדוכתא דמליחי מיא לא מצי קאי והא קחזינן דקאי אלא משום דלא מרבה טינא דג טמא אמר רבינא האידנא דקא שפכי ביה נהר גוזא ונהר גמדא אסירי

Rather, perhaps Abaye permitted the fish because the water is salty, and these non-kosher fish are not able to exist in a place of salty water since they do not have scales. This, too, is not the case, since we see that non-kosher fish exist in salty water. Rather, Abaye permitted the small fish in the Bav River because the mud in that river is not suitable for non-kosher fish to reproduce. The conditions in the river render it an unproductive habitat for non-kosher fish. Ravina says: Nowadays, as the government built canals between the rivers, and the Goza River and the Gamda River spill into the Bav and carry non-kosher fish there, it is prohibited to eat the small fish without thorough inspection.

אמר אביי האי חמרא דימא שרי תורא דימא אסיר וסימניך טמא טהור טהור טמא

The Gemara cites several other statements of amora’im that concern the halakhic status of fish. Abaye says: This creature known as the sea donkey [ḥamara deyamma] is permitted; the creature known as the sea ox [tora deyamma] is prohibited, and your mnemonic to remember this halakha is: Impure is pure, and pure is impure, i.e., the name of an animal which is non-kosher on land is kosher in the sea, and that which is kosher on land is non-kosher in the sea.

אמר רב אשי שפר נונא שרי קדש נונא אסיר וסימניך קדש לה׳ איכא דאמרי קבר נונא אסור וסימניך קברי גוים

Rav Ashi said: The type of fish known as shefar nuna is permitted, and the type of fish known as kadesh nuna is prohibited, and your mnemonic to remember this halakha is: That which is holy [kodesh] is to the Lord, and not for humans. And some say that Rav Ashi said: The type of fish known as kevar nuna is prohibited, and your mnemonic is: The grave [kever] is impure like the graves of gentiles.

רבי עקיבא איקלע לגינזק אייתו לקמיה ההוא נונא דהוה דמי לחיפושא חפייה בדיקולא חזא ביה קלפי ושרייה רב אשי איקלע לטמדוריא אייתו לקמיה ההוא נונא דהוה דמי לצלופחא נקטיה להדי יומא חזא דהוה ביה צימחי ושרייה

The Gemara relates several incidents involving Sages and their rulings with regard to fish. Rabbi Akiva happened to come to Ginzak and they brought before him a certain fish that was similar to a ḥippusha, a non-kosher aquatic creature. When he enclosed it in a basket he saw that it had scales which it shed as it struggled to escape from the basket, and he permitted it on that basis. Rav Ashi happened to come to Tamduria where they brought before him a certain fish that was similar to an eel [tzelofḥa]. He took it out and held it against the light of day and saw that there were thin scales on it, and he permitted it.

רב אשי איקלע לההוא אתרא אייתו לקמיה נונא דהוי דמי לשפרנונא חפייה במשיכלי חיורי חזא ביה קלפי ושרייה רבה בר בר חנה איקלע לאקרא דאגמא קריבו ליה צחנתא שמעיה לההוא גברא דהוה קרי ליה באטי

Rav Ashi also happened to come to a certain land where they brought before him a fish that was similar to a shefarnuna. He enclosed it in a white vessel and saw that it shed dark scales, which he could see against the white background of the container, and he permitted it. Rabba bar bar Ḥana happened to come to Akra DeAgma and they brought him some tzaḥanta, a dish prepared from small fish. He heard a certain man calling it batei, the name of a non-kosher sea creature.

אמר מדקא קרי ליה באטי שמע מינה דבר טמא אית ביה לא אכל מיניה לצפרא עיין בה אשכח ביה דבר טמא קרי אנפשיה לא יאנה לצדיק כל און

Rabba bar bar Ḥana said to himself: From the fact that he called it batei, I can conclude from here that there is a non-kosher substance in the tzaḥanta. And he did not eat from it that night. In the morning, he examined the dish and in fact found a non-kosher substance in it. He read the following verse about himself: “No sin shall befall the righteous” (Proverbs 12:21).

והקורט של חילתית מאי טעמא משום דמפסקי ליה בסכינא אף על גב דאמר מר נותן טעם לפגם מותר אגב חורפיה דחילתיתא מחליא ליה שמנוניתא והוה ליה כנותן טעם לשבח ואסור

§ The mishna teaches: And a sliver of ḥiltit may not be consumed, although one may derive benefit from it. The Gemara asks: What is the reason that it is prohibited? It is because they slice it with a knife on which there is presumably non-kosher residue. And even though the Master said that a prohibited substance that imparts flavor to the detriment of the mixture is permitted, that principle does not apply in this case because as a result of the sharpness of the ḥiltit, the act of slicing it with a knife sweetens, i.e., enhances, the taste of the non-kosher residue. And there-fore it is like a prohibited substance that imparts flavor to the enhancement of the mixture, and it is prohibited.

עבדיה דרבי לוי הוה קא מזבין חילתיתא כי נח נפשיה דרבי לוי אתו לקמיה דרבי יוחנן אמרו ליה מהו למיזבן מיניה אמר להו עבדו של חבר הרי הוא כחבר

The Gemara relates that the gentile slave of Rabbi Levi would sell ḥiltit, and it was permitted to purchase it from him as he was the slave of a Sage. When Rabbi Levi passed away, they came before Rabbi Yoḥanan and said to him: Now that Rabbi Levi has passed, what is the halakha with regard to whether or not it is permitted to purchase ḥiltit from his gentile slave? Rabbi Yoḥanan said to them: The slave of a ḥaver, one devoted to the meticulous observance of mitzvot, especially halakhot of ritual purity, teruma, and tithes, is as a ḥaver himself, and therefore it is permitted to buy ḥiltit from him.

רב הונא בר מניומי זבן תכילתא מאנשי דביתיה דרב עמרם חסידא אתא לקמיה דרב יוסף לא הוה בידיה

The Gemara relates another incident that involves the status of a ḥaver and his household. Rav Huna bar Minyumi purchased sky-blue dye [tekhelta] from the people of the household, i.e., the wife, of Rav Amram the pious. One may purchase sky-blue dye for ritual fringes only from a reliable individual, as it is easy to counterfeit it. Rav Huna then came before Rav Yosef to ask if he could rely on her assurance that it was usable for the mitzva. The answer was not available to Rav Yosef.

פגע ביה חנן חייטא אמר ליה יוסף עניא מנא ליה בדידי הוה עובדא דזביני תכילתא מאנשי דביתיה דרבנאה אחוה דרבי חייא בר אבא ואתאי לקמיה דרב מתנא לא הוה בידיה אתאי לקמיה דרב יהודה מהגרוניא אמר לי נפלת ליד הכי אמר שמואל אשת חבר הרי היא כחבר

Later, Ḥanan the tailor happened to meet Rav Huna, and he said to him: From where could poor Rav Yosef have known the answer to this question? Ḥanan continued: There was an incident in which I was involved, as I purchased sky-blue dye from the people of the household, i.e., the wife, of Rabena’a, brother of Rabbi Ḥiyya bar Abba, and I came before Rav Mattana to ask him the same question, and the answer was not available to him either. I then came before Rav Yehuda of Hagronya, who said to me: You have fallen into my hand, i.e., I am the only one who can answer your question. This is what Shmuel says: The wife of a ḥaver is herself considered like a ḥaver, and you may therefore rely on her statement.

תנינא להא דתנו רבנן אשת חבר הרי היא כחבר עבדו של חבר הרי הוא כחבר חבר שמת אשתו ובניו ובני ביתו הרי הן בחזקתן עד שיחשדו וכן חצר שמוכרין בה תכלת הרי הן בחזקתן עד שתיפסל

The Gemara comments: We learn here that which the Sages taught explicitly in a baraita: The wife of a ḥaver is like a ḥaver; the slave of a ḥaver is like a ḥaver. Furthermore, with regard to a ḥaver that died, his wife and children and members of his household remain in their presumptive status until they are suspected of engaging in inappropriate deeds. And similarly, with regard to a courtyard in which they sell sky-blue dye, it remains in its presumptive status as a place in which kosher sky-blue dye is sold until it is disqualified due to unscrupulous behavior.

תנו רבנן אשת עם הארץ שנשאת לחבר וכן בתו של עם הארץ שנשאת לחבר וכן עבדו של עם הארץ שנמכר לחבר כולן צריכין לקבל דברי חברות אבל אשת חבר שנשאת לעם הארץ וכן בתו של חבר שנשאת לעם הארץ וכן עבדו של חבר שנמכר לעם הארץ אינן צריכין לקבל דברי חברות לכתחלה דברי רבי מאיר

The Sages taught: The wife of one who is not careful to keep the particulars of certain halakhot [am ha’aretz], who later marries a ḥaver, and likewise the daughter of an am ha’aretz who marries a ḥaver, and likewise the slave of an am ha’aretz who is sold to a ḥaver, must all accept upon themselves the commitment to observe the matters associated with ḥaver status. But the wife of a ḥaver who later marries an am ha’aretz, and likewise the daughter of a ḥaver who marries an am ha’aretz, and likewise the slave of a ḥaver who was sold to an am ha’aretz, these people need not accept upon themselves the commitment to observe the matters associated with ḥaver status ab initio. This is the statement of Rabbi Meir.

רבי יהודה אומר אף הן צריכין לקבל דברי חברות לכתחלה וכן היה רבי שמעון בן אלעזר אומר מעשה באשה אחת שנשאת לחבר והיתה קושרת לו תפילין על ידו נשאת למוכס והיתה קושרת לו קשרי מוכס על ידו

Rabbi Yehuda says: They too must accept upon themselves the commitment to observe the matters associated with ḥaver status ab initio. And similarly, Rabbi Shimon ben Elazar would illustrate this point and say: There was an incident involving a certain woman who married a ḥaver and would tie for him phylacteries on his hand, and she later married a tax collector and would tie for him tax-seals on his hand, which shows that her new husband had a great influence on her level of piety.

אמר רב חבית אסור בחותם אחד חמפג מותר בחותם אחד חלב בשר יין תכלת

§ Rav says: The substances represented by the acronym ḥet, beit, yod, tav are prohibited if they were deposited with a gentile while they were sealed with only one seal. Those represented by the acronym ḥet, beit, peh, gimmel are permitted if they were deposited with a gentile while they were sealed with one seal. The Gemara elaborates: Milk [ḥalav], meat [basar], wine [yayin], and sky-blue dye [tekhelet]

אסורין בחותם אחד חילתית מורייס פת גבינה מותרין בחותם אחד

are all prohibited when they are found with only one seal; ḥiltit, fish stew [morayes], bread [pat], and cheese [gevina] are all permitted when they are found with one seal.

פת למאי ניחוש לה אי משום איחלופי קרירא בחמימא מידע ידיע דחיטי בדשערי נמי מידע ידיע אי כי הדדי כיון דאיכא חותם אחד לא טרח ומזייף

The Gemara explains why only one seal is necessary for bread. With regard to what need we be concerned in the case of bread, that one might have thought it requires two seals? If it is due to the concern for the gentile exchanging the fresh bread of the Jew with his own bread that is less fresh, the difference between cold bread and warm bread is known, and the Jew will realize that there has been an exchange. Likewise, if there is a concern that a gentile might exchange the more valuable wheat bread of the Jew with his own less valuable barley bread, the Jew will also know about it in this case. And if it is due to the concern that a gentile might exchange similar kinds of bread with each other, it can be assumed that since there is one seal the gentile will not trouble himself and forge another seal just to exchange bread of equal value.

ורב מאי שנא גבינה דלא טרח ומזייף חלב נמי לא טרח ומזייף אמר רב כהנא אפיק חלב ועייל חתיכת דג שאין בה סימן

The Gemara asks: And according to the opinion of Rav, what is different about cheese that it requires only one seal whereas milk requires two? If the reason is that a gentile will not trouble himself and forge a different seal, as cheese is generally inexpensive and the small profit he might make is not worth such an effort, this reasoning should apply to milk also, as he will not trouble himself and forge a new seal in this case either. Rav Kahana said: Remove the term: Milk, from Rav’s statement, and enter instead: A piece of fish that has no sign of kashrut.

היינו בשר תרי גווני בשר

The Gemara raises an objection: Rav could not have been teaching that a piece of fish with no signs of kashrut requires two seals, as fish is the same as meat, which is already included in the list of items that require two seals. The Gemara explains that there are two categories of meat: Animal meat and fish meat. Since one might have thought that they are subject to different halakhot, Rav therefore teaches that both require two seals.

ושמואל אומר בית אסור בחותם אחד מחג מותר בחותם אחד בשר יין תכלת אסורין בחותם אחד מורייס חילתית גבינה מותרין בחותם אחד לשמואל חתיכת דג שאין בה סימן היינו בשר תרי גווני בשר לא אמרינן

The Gemara cites a different set of lists than that presented by Rav. And Shmuel says: The substances represented by the acronym beit, yod, tav are prohibited when sealed with one seal; those represented by the acronym mem, ḥet, gimmel, are permitted when sealed with one seal. The Gemara explains: Meat [basar], wine [yayin], and sky-blue dye [tekhelet] are prohibited when sealed with a single seal; fish stew [morayes], ḥiltit, and cheese [gevina], are permitted when sealed with a single seal. The Gemara comments: According to Shmuel, a piece of fish that has no sign of kashrut is the same as meat, and we do not say that there is a difference between two categories of meat. Consequently, he does not include in his list a piece of fish that has no sign of kashrut.

תנו רבנן אין לוקחין ימח מחג בסוריא לא יין ולא מורייס ולא חלב ולא מלח סלקונדרית ולא חילתית ולא גבינה אלא מן המומחה וכולן אם נתארח אצל בעל הבית מותר

The Sages taught: One may not purchase foods represented by the acronym yod, mem, ḥet; mem, ḥet, gimmel in Syria, not even from Jews. The Gemara elaborates: One may not purchase wine [yayin], nor fish stew [morayes], nor milk [ḥalav], nor salkondarit salt [melaḥ salkondarit], nor ḥiltit, nor cheese [gevina], except when purchased from an expert with a reputation for knowing and upholding the halakhot of kashrut. And with regard to all of them, if one is a guest in the home of his host, they are permitted, as a Jew is assumed to keep the halakhot of kashrut in his own home.

מסייע ליה לרבי יהושע בן לוי דאמר רבי יהושע בן לוי שגר לו בעל הבית לביתו מותר מאי טעמא בעל הבית לא שביק היתירא ואכל איסורא וכי משגר ליה ממאי דאכיל משדר ליה

The Gemara adds: This supports the statement of Rabbi Yehoshua ben Levi, as Rabbi Yehoshua ben Levi says: If a homeowner sent someone a package of food to his house, the food is permitted. What is the reason? It is because a homeowner does not leave aside permitted foods and eat prohibited foods, and when he sends food to another, he sends it from that which he eats himself, even though one may not be allowed to purchase food from that individual.

ומלח סלקונדרית מאי מלח סלקונדרית אמר רב יהודה אמר שמואל מלח שכל סלקונדרי רומי אוכלין אותה תנו רבנן מלח סלקונדרית שחורה אסורה לבנה מותרת דברי רבי מאיר רבי יהודה אומר לבנה אסורה שחורה מותרת רבי יהודה בן גמליאל משום רבי חנינא בן גמליאל אומר זו וזו אסורה

§ The mishna teaches that salkondarit salt is prohibited. The Gemara asks: What is salkondarit salt? Rav Yehuda says that Shmuel says: It is the salt that all Roman bakers [salkondarei] eat. The Sages taught: With regard to salkondarit salt, black salt is prohibited, whereas white salt is permitted; this is the statement of Rabbi Meir. Rabbi Yehuda says: White salt is prohibited; black salt is permitted. The Gemara cites a third opinion: Rabbi Yehuda ben Gamliel says in the name of Rabbi Ḥanina ben Gamliel: This and that, i.e., both white and black salkondarit salt, are prohibited.

אמר רבה בר בר חנה אמר רבי יוחנן לדברי האומר לבנה אסורה קירבי דגים לבנים טמאים מעורבין בה לדברי האומר שחורה אסורה קירבי דגים שחורים טמאים מעורבין בה

The Gemara cites an explanation of this dispute. Rabba bar bar Ḥana says that Rabbi Yoḥanan says: According to the statement of the one who says that white salkondarit salt is prohibited, it is suspected that the intestines of white non-kosher fish are mixed in it, and this is the reason for the prohibition. According to the statement of the one who says that black salt is prohibited, it is suspected that the intestines of black non-kosher fish are mixed in it.

לדברי האומר זו וזו אסורה זה וזה מעורבין בה אמר רבי אבהו משום רבי חנינא בן גמליאל זקן אחד היה בשכונתנו שהיה מחליק פניה בשומן חזיר

According to the statement of the one who said this and that are prohibited, he is concerned that this and that, i.e., the intestines of both white and black fish, are mixed in white and black salt, respectively. The Gemara mentions an additional problem with salkondarit salt: Rabbi Abbahu says in the name of Rabbi Ḥanina ben Gamliel: There was a certain elder in our neighborhood who would smooth its surface with pig fat.

הרי אלו אסורים למעוטי מאי לחזקיה למעוטי בידוע לרבי יוחנן למעוטי מורייס וגבינת בית אונייקי וסתמא כרבי מאיר

§ The mishna further teaches that the list of items it mentioned are all prohibited. The Gemara asks: Since the mishna began by stating that the items it lists are prohibited for consumption, what does this apparently redundant conclusion serve to exclude? The Gemara answers: According to the opinion of Ḥizkiyya cited on 38b, it serves to exclude cases where it is known that wine of gentiles’ was added to the foods, as one may not even derive benefit from such foods. According to the opinion of Rabbi Yoḥanan, it serves to exclude fish stew and cheese of Beit Unyaki, as it is prohibited to derive benefit from these, and accordingly, the unattributed statement in this mishna is in accordance with the opinion of Rabbi Meir, cited in the previous mishna (29b).

מתני׳ ואלו מותרין באכילה חלב שחלבו גוי וישראל רואהו והדבש והדבדבניות אף על פי שמנטפין אין בהן משום הכשר משקה וכבשין שאין דרכן לתת לתוכן יין וחומץ וטרית שאינה טרופה וציר שיש בה דגה ועלה של חילתית וזיתי גלוסקאות המגולגלין

MISHNA: And these are permitted for consumption: Milk that was milked by a gentile and a Jew watched him doing so; and honey; and grape clusters [davdevaniyyot] which, despite the fact that they are dripping juice, are not subject to the halakhot of susceptibility to ritual impurity caused by contact with that liquid; and pickled vegetables whose usual manner of preparation does not involve adding wine and vinegar to them; and tarit fish that is not minced; and brine that has fish in it; and the leaf of a ḥiltit plant; and rolled olive cakes [geluskaot].

רבי יוסי אומר השלחין אסורין החגבים הבאים מן הסלולה אסורין מן ההפתק מותרין וכן לתרומה

Rabbi Yosei says: Overripe olives are prohibited. Locusts that come from a salesman’s basket are prohibited, whereas those that come from the storeroom [heftek] are permitted; and likewise with regard to the portion of the produce designated for the priest [teruma], as will be explained in the Gemara.

גמ׳ תנינא להא דתנו רבנן יושב ישראל בצד עדרו של גוי וגוי חולב ומביא לו ואינו חושש היכי דמי אי דליכא דבר טמא בעדרו פשיטא ואי דאיכא דבר טמא בעדרו אמאי

GEMARA: We learn from the mishna that which the Sages taught explicitly in a baraita: A Jew may sit beside a gentile’s flock and wait while the gentile milks his animals and brings the milk to the Jew, and he not need be concerned, even if he cannot see the milking process from his seated position. The Gemara asks: What are the circumstances of this case? If it is known that there is no non-kosher animal in the gentile’s flock, isn’t it obvious that the milk is permitted? Why would the baraita teach an obvious halakha? And if there is a non-kosher animal in his flock, then why is the milk permitted, considering the fact that the Jew could not see the gentile from where he sat?

לעולם דאיכא דבר טמא וכי קאי חזי ליה וכי יתיב לא חזי ליה מהו דתימא כיון דיתיב לא חזי ליה ניחוש דלמא מייתי ומערב ביה קא משמע לן כיון דכי קאי חזי ליה אירתותי מירתת ולא מיערב ביה

The Gemara explains: Actually, this is referring to a case where there is a non-kosher animal in the flock, and when the Jew is standing he can see the gentile, but when he is sitting he cannot see the gentile. Lest you say: Since when the Jew is sitting, he cannot see the gentile, we should be concerned that perhaps the gentile will bring non-kosher milk and mix it with the kosher milk, the baraita therefore teaches us that since when the Jew is standing, he can see him, the gentile is fearful of being caught and does not mix anything into the milk.

והדבש דבש למאי ניחוש לה אי משום איערובי מיסרא סרי אי משום בישולי גוים נאכל כמו שהוא חי אי משום גיעולי גוים נותן טעם לפגם הוא ומותר

§ The mishna teaches: And the honey of gentiles is permitted. The Gemara explains: For what need we be concerned with regard to honey? If it is due to the concern that a gentile might mix wine with it, honey spoils when it is mixed with wine, and therefore a gentile would not do so. If it is due to the cooking of gentiles, this too does not apply, because it is eaten as it is, i.e., raw. If it is due to the concern that the honey might have absorbed prohibited taste from vessels of gentiles that require purging, this does not apply either, as it is a prohibited substance that imparts flavor to the detriment of the mixture, and such a case is permitted. Since none of these concerns are relevant, the honey is permitted.

והדבדבניות אף על פי שמנטפות אין בהן משום הכשר משקה ורמינהי הבוצר לגת שמאי אומר הוכשר הלל אומר לא הוכשר ואודי ליה הלל לשמאי

§ The mishna further teaches: And grape clusters which, despite the fact that they are dripping juice, are not subject to the halakhot of susceptibility to ritual impurity caused by contact with that liquid. And the Gemara raises a contradiction from the following baraita: With regard to one who harvests grapes in order to take them to the press and crush them, there is a dispute as to whether or not the liquid that seeps from the grapes renders them susceptible to ritual impurity. Shammai says: It has become susceptible to ritual impurity, and Hillel says: It has not become susceptible. And eventually Hillel conceded to the opinion of Shammai. This shows that the juice that seeps out of grapes does render them susceptible to ritual impurity, which apparently contradicts the ruling of the mishna.

התם קא בעי ליה למשקה הכא לא קא בעי ליה למשקה

The Gemara explains: There, in the case of the baraita, he wants the juice as a beverage, and one’s intention influences the capability of certain liquids to render substances susceptible to ritual impurity. Therefore, the liquid that seeps from the grapes renders them susceptible to ritual impurity. Here, in the case of the mishna, he does not want the juice as a beverage, and therefore the grapes are not rendered susceptible to impurity.

וטרית שאינה טרופה תנו רבנן איזו היא טרית שאינה טרופה כל שראש ושדרה ניכר ואיזו ציר שיש בה דגה כל שכילבית אחת או שתי כילביות

§ The mishna further teaches: And tarit fish that is not minced and brine that has fish in it are permitted. The Sages taught: What is considered tarit that has not been minced? Any fish whose head and spine are recognizable. And what is considered brine that has fish in it? Any brine that has one kilbit or two kilbiyot
