THE SOURCE FOR THE TYPES OF FOOD THAT MAY BE BOUGHT (Yerushalmi Maaser Sheni Perek 1 Halachah 3 Daf 7a)

מתני' דרבי עקיבה [היא] דלא כרבי ישמעאל.


(The Mishnah prohibits buying water and salt with Maaser Sheni money, but therefore allows fish, grasshoppers and mushrooms.) This follows the opinion of R. Akiva and not R. Yishmael...

רבי ישמעאל דריש (דברים יד) ונתת הכסף בכל אשר תאוה נפשך כלל בבקר ובצאן ביין ובשכר פרט ובכל אשר תאוה נפשך הרי כלל אחר. כלל ופרט וכלל אי אתה דן אלא כעין הפרט לומר לך מה הפרט מפורש דבר שהוא וולד וולדות הארץ אף אין לי אלא דבר שהוא וולד וולדות הארץ.


R. Yishmael expounded - the pasuk states (Devarim 14:26), "And you shall turn that money into whatever your soul desires" - that is a generalization; "cattle, sheep, wine or beer" - they are specifications; "or whatever your soul desires" - is another generalization. When there is a generalization, then a specification, then another generalization - you only include that which is like the specification. Just as the specifications are things that grow from the ground or things that are derived from that; so too one must purchase something that grows from the ground or something derived from that.

רבי עקיבה מפרש מה הפרט מפורש דבר שהוא פרי וולד פירי ומכשירי פירי אף אין לי אלא דבר שהוא פרי וולד פירי ומכשירי פירי.


R. Akiva explained that just as the specification is a product, it comes from a product (e.g. wine comes from grape pulp) and it gives flavor to other products (e.g. wine is used to flavor a dish); so too one must purchase something that is a product, it comes from a product and it gives flavor to other products.

מה נפק מן ביניהון דגים וחגבים כמהין ופטריות כרבי עקיבה נקחין בכסף מע"ש.


What's the practical difference between (R. Yishmael and R. Akiva)? Fish, grasshoppers and mushrooms may be bought with Maaser Sheni money according to R. Akiva.

א"ר חגי מתני' אמרה (כן) שאין מחללין מעות על פירות בריחוק מקום.


(R. Chagai): The Mishnah taught (about one who inadvertently used Maaser Sheni money to buy produce outside Yerushalayim. This) teaches that one cannot transfer the Kedushah of Maaser Sheni money onto produce that is outside Yerushalayim.

אמרה קומי רבי אבינא וקלסי' אמרה קומי רבי ירמיה וקנתריה. והתנינן מעות בירושלים ופירות במדינה


R. Chagai said it in front of R. Avina and he praised it. He said it in front of R. Yirmiyah and he criticized it, asking from the later Mishnah (in Perek 3), 'If a person had Maaser Sheni money in Yerushalayim and Chulin produce outside Yerushalayim (he may exchange it by saying...)'. (This shows that one may transfer money onto produce that is outside Yerushalayim...?)

שנייא היא שהיה (אחר)[אחד] מקום.


Rebuttal: That's different, because one of the two (the money or the produce) are inside Yerushalayim.

כד נפיק רבי חגי אשכח תני מעות ופירות בירושלים מעות ופירות במדינה. אמר אי שמיע רבי ירמיה הדא מילתא יאות קנטרי.


When R. Chagai left, he discovered a Baraisa that taught that if they are both inside or both outside Yerushalayim (one may transfer...). He said, "If R. Yirmiyah would have heard that Baraisa, he would certainly have had his question."

בעי מיחזור ביה.


As a result of this Baraisa, R. Chagai wished to retract his ruling.

אמר ליה רבי זעירא לא תיחזור בך דאמר רבי לעזר דרבי מאיר ורבנין דמאי הא בודאי לא.


(R. Zeira to R. Chagai): Don't retract, as R. Elazar explained that the Mishnah (in Perek 3) follows all opinions (even though R. Meir and the Chachamim disagreed in a Mishnah in Maseches Demai (1:2) over exchanging Demai).

מן מה דאמר (ר"א)[רבי אימי] דרבי מאיר היא הדא אמרה היא דמאי היא ודאי


However, according to R. Imi who said that the Mishnah (in Perek 3) is the opinion of R. Meir, both Demai and certain Tevel are the same.
