(Mishnah): Ma'aser Sheni produce that entered into Yerushalayim and then became Tamei, whether it was from an Av HaTumah (such as a dead Sheretz) or from a Vlad HaTumah (meaning from a Rishon LeTumah - a Rabbinic first degree Tumah), whether it became Tamei inside or outside of Yerushalayim (and then brought in)...

(Beis Shammai): It must be redeemed, but the redeemed produce must be eaten within Yerushalayim, except if it became Tamei from an Av HaTumah outside of Yerushalayim.

(Beis Hillel): Everything is redeemed and can be eaten outside of Yerushalayim, except that which became Tamei from a Vlad HaTumah inside (Yerushalayim, which may not be removed.)

(Gemara): The pasuk states (Devarim 14:24), "because you cannot carry it'' (you should redeem it onto coins).

What's the case? If it is distant, there's already a pasuk that states, "If (the place) is distant from you''. If it is near, the pasuk states, "If the place is distant from you'' (only then you may redeem). Rather, what's the meaning of "because you cannot 'carry it'"? You are not able to eat them because they are Tamei. And the pasuk states, "And you shall give the money'' - (but even though you cannot eat them, you can redeem them).

Baraisa (Bar Kapara): An Av HaTumah is from the Torah, and a Vlad HaTumah is Rabbinic.

(R. Yochanan): Both are from the Torah.

Question (against R. Yochanan): Beis Shammai said that everything may be redeemed and eaten inside, except for that which became Tamei from an Av HaTumah outside...

What's the difference between a Vlad HaTumah outside and an Av HaTumah outside - aren't both from the Torah?

Question: Isn't there even a question against R. Yochanan from Beis Hillel, who say that everything is redeemed and eaten outside, aside from that which was made Tamei from a Vlad HaTumah inside...

What's the difference between a Vlad HaTumah inside and an Av HaTumah inside - aren't they both from the Torah?

The Rabbanan directed their questions against Bar Kapara, since R. Yochanan's opinion has certainly been disproved...

(Question against Bar Kapara): Beis Shammai say that everything is redeemed and eaten inside, aside from that which became Tamei from an Av HaTumah outside...

What's the difference in an Av HaTumah whether it's outside or inside - both are from the Torah?

Answer: (Since it was brought in Tahor) people might say that they saw Tahor Ma'aser Sheni brought in and then taken out of Yerushalayim and eaten there.

Question: If so, when it became Tamei through an Av HaTumah in Yerushalayim, it should not be redeemed, lest people say that they saw Tahor Ma'aser Sheni brought in and redeemed in Yerushalayim?

Rather, the reason is that when it was brought in Tahor, the walls absorbed it and if it then became Tamei inside, it is redeemed and eaten inside. However, when it became Tamei outside, the walls don't absorb it.

Question: Isn't there even a question against Bar Kapara from Beis Hillel, who said that everything is redeemed and eaten outside, aside from that which became Tamei from a Vlad HaTumah inside...

What's the difference in a Vlad HaTumah whether it's outside or inside - both are Rabbinic?

Answer: When he brought them in on condition that the walls don't absorb them (since he brought them in already Tamei).

(R. Zeira): (If he can do this when it became Tamei from a Vlad HaTumah since it is only Rabbinic but on a Torah level it is Tahor), this shows that if a person brought in Tahor Ma'aser Sheni on condition that the walls don't absorb it, the walls do not absorb.

Question (R. Yona): How could you say this if on a Torah level it is Tahor? Rather, if he transgressed and redeemed it, it would be valid.

Question (R. Yaakov of the South to R. Yosi): (We said earlier that according to Beis Shammai) if it became Tamei outside Yerushalayim and was brought in, it may not be removed, as people might say that they saw Ma'aser Sheni being brought in and then out of Yerushalayim. If so, it also should not be redeemed, as people might say that they saw Ma'aser Sheni brought into Yerushalayim and then redeemed there?

Answer (R. Yosi): It's known when a person brings in Ma'aser Sheni and then removes it, but it's not known when Ma'aser Sheni is redeemed.

Question (R. Chiya bar Ada to R. Mana): (According to Beis Hillel) if it became Tamei through a Vlad HaTumah inside and it was redeemed in order to eat it inside and it then became Tamei through an Av HaTumah; do we say that it wasn't fully redeemed originally since it had only contracted Rabbinic Tumah, so it now requires another redemption after it contracted a Torah Tumah?

Answer: If the original money used for the redemption is still intact, he can redeem onto them a second time. If not, he must redeem them onto different coins.

One does not incur lashes for the first coins or the second coins (if he took them out of Yerushalayim and bought and ate food with them there).

Question (R. Yona): (According to the Rabbanan of the next Mishnah, produce bought with Ma'aser Sheni money that became Tamei may be redeemed even outside Yerushalayim.) Does this even apply to when it became Tamei from a Vlad HaTumah?

Answer (R. Mana): The walls 'take hold' of Ma'aser Sheni produce (that they may only be redeemed if they became Tamei) and food bought with Ma'aser Sheni money 'takes hold' (that they not be redeemed). Therefore, that which was said about the walls (that if the produce became Tamei from a Vlad HaTumah it must be eaten inside), also applies to that which was bought (that if they became Tamei from a Vlad HaTumah, they may be redeemed and the money spent on food in Yerushalayim).
