(R. Yochanan): Beis Tzevi'ah that they said, it is whether it is inside [the Kli] or the outside, the way delicate people hold it.

(R. Ze'irah): (When do we distinguish an interior Beis Tzevi'ah from the rest of the Kli?) Do not say that it is dry, for [Stam] hands are not Metamei if it is dry!

However, also you cannot say that it is full of liquid, for once he touches it (anywhere, all the liquid is Tamei, and) he was Metamei [the entire Kli]!

Rather, the case is, [only Beis Tzevi'ah] is wet with liquid.

Rebuttal (R. Yochanan citing R. Benayah): They made liquid of Beis Tzevi'ah like liquids of Beis Mitbechai (where they rinse Korbanos). Just like you say there that the liquids of Beis Mitbechai (blood and water) are Tehorim in their place and Tamei elsewhere, so liquids of Beis Tzevi'ah are Tehorim in their place and Tamei elsewhere [on the Kli. We can say that the Kli is full of liquid.]

(R. Simon citing R. Yehoshua ben Levi): If a liquid of Beis Mitbechai [contacted Tum'ah inside, and] went outside, it is Tamei.

Question (Beraisa): If liquids of Beis Mitbechai went outside, they keep their Kedushah (Taharah).

R. Yosah said that R. Simon answered [this himself]. R. Chinena said that R. Simon answered this in the name of R. Yehoshua ben Levi. [The Beraisa discusses] when they went outside and returned. (They return to be Tehorim. We explained the Sugya like HA'GAON RAV C. KANIEVSKY, SHLITA.)

If an upper liquid (in Beis Tzevi'ah) became Tamei (touched Tum'ah), and it was flowing down [on the Kli, where it becomes Tamei], R. Ba and R. Bun bar Chiyah argued about this. One said that in its place it is Tahor, but when it descended below, it is Tamei. (We explained this like SHA'AREI TORAS ERETZ YISRAEL);

The other said that since it comes from power of Taharah, it is Tahor.

(R. Acha citing R. Ze'irah): This [distinction of inside and outside of a Kli for Terumah] refers to [Tum'ah through] liquids that became Tamei through food, but liquids that became Tamei through a Sheretz, [all parts of the Kli] are Tamei.

(Mishnah): All Kelim have exterior and interior, and they have Beis Tzevi'ah;

R. Tarfon says, [Beis Tzevi'ah is only] for a big trough of wood. R. Akiva says, it is [only] for cups.

R. Meir says, it is whether the hands were Tamei or Tahor;

R. Yosi says, it is only when the hands were Tahor;

According to R. Meir, if his hands were Tamei and the back of the cup was Tahor, and liquid is outside on back of the cup, and he held it by Beis Tzevi'ah, obviously the liquid does not become Tamei from his hand to be Metamei the cup.

Question: [Does he say that] just like liquid does not become Tamei from the hand to be Metamei the cup, so liquid does not become Tamei from the hand to be Metamei a loaf elsewhere?

Answer: We learn from the following [Beraisa]. If Tahor liquids were put on Beis Tzevi'ah of a cup, if a Tamei loaf touched them, it was Metamei them;

Regarding what was it Metamei them - is it not to be Metamei a loaf elsewhere?!

Inference: It is because [the liquids on Beis Tzevi'ah contacted Tum'ah] from a loaf, but from the hand, no (they would not become Tamei)!

Question: If a liquid was put on the hand, and he held it in Beis Tzevi'ah, [do we say that] even so, liquid does not become Tamei from the hand to be Metamei the cup? (Perhaps we say so only when the liquids were on the cup, but not if they were on the hand.)

Answer: We learn from the following [Beraisa]. If Tamei liquids were in the ground, and they touched a cup, whose back is Tahor, on Beis Tzevi'ah, it was Metamei them.

Inference: It is because [the liquids were in the] ground, but on the hand, no (they would not become Tamei)!

And according to R. Yosah (R. Yosi above), if his hands were Tahor and the back of the cup was Tamei, and liquid is on the back of his hand, and he held it by Beis Tzevi'ah, obviously the liquid does not become Tamei from the cup to be Metamei the hand.

Question: [Does he say that] just like liquid does not become Tamei from the cup to be Metamei the hand, so liquid does not become Tamei from the cup to be Metamei a loaf elsewhere?

Answer: We learn from the following [Beraisa]. If Tahor liquids were put in the ground, and they touched a cup, whose back is Tahor, on Beis Tzevi'ah, the liquids became Tamei;

For what did they become Tamei - is it not to be Metamei a loaf elsewhere?!

Inference: It is because [the liquids were] in the ground, but if they were on the hand, no (they would not become Tamei)!

Question: If a liquid was put on the back of a cup, and he held it in Beis Tzevi'ah, [do we say that] even so, liquid does not become Tamei from the cup to be Metamei the hand? (Perhaps we say so only when the liquids were on the hand, but not if they were on the cup.)

Answer: We learn from the following [Beraisa]. If Tamei liquids were in Beis Tzevi'ah of a cup, and they touched a Tahor loaf, it became Tamei.

Inference: It is because [the liquids on Beis Tzevi'ah contacted Tum'ah] from a loaf, but from the hand, no (they would not become Tamei! We explained the entire Sugya like HA'GAON RAV C. KANIEVSKY, SHLITA.)
