(R. Yonason citing Rebbi): One who eats a Shelishi of Terumah, his body is disqualified from eating Terumah.

Question (R. Shmuel bar Rav Yitzchak): Does Rebbi hold like R. Eliezer?!

(Mishnah): One who eats a Rishon, he becomes a Rishon. One who eats a Sheni, he becomes a Sheni. One who eats a Shelishi, he becomes a Shelishi. (R. Eliezer says so. R. Yehoshua says, one who eats a Shelishi, he becomes a Sheni for Kodesh, but not for Terumah.)

Answer: [Rebbi's law] is like everyone. It is [a stringency not to eat,] so he will refrain from [eating Tamei] Terumah. (Regarding touching, Rebbi could hold like R. Eliezer or R. Yehoshua.)

Question: Do we similarly say that one who eats a Sheni of Ma'aser, his body is disqualified from eating Ma'aser?

Answer: We learn from the following [Mishnah, which teaches] Chachamim forbid Ma'aser, and R. Shmuel said in the name of R. Ze'irah, what does it mean "Chachamim forbid Ma'aser''? His body is disqualified from eating Ma'aser.

Question: Do we similarly say that one who eats a Revi'i of Kodesh, his body is disqualified from eating Kodesh?

Answer: We learn from the following. R. Yirmeyah said in the name of R. Ba bar Mamal, they made [an Onen] like one who ate a Revi'i of Kodesh (he may not eat Kodesh). This teaches that one who eats a Revi'i of Kodesh, his body is disqualified from eating Kodesh.

Question: This teaches about [one who ate a Revi'i of] actual Kodesh. Do we say so even about [one who eats a Revi'i of] Chulin Al Taharas ha'Kodesh?

Answer: We learn from the following Mishnah. One who slaughters a Behemah, Chayah or bird, and blood did not come out, it is Kosher, and one may eat it with dirty hands (it was not Huchshar);

Even though it was not Huchshar through blood, R. Shimon says that it was Huchshar through Shechitah.

Note: There is an implied question. Surely we discuss Chulin. Dirty hands are a Sheni. Even if there was Hechsher, they are not Metamei the meat!

Answer (R. Lazar citing R. Hoshayah): Our Mishnah discusses Chulin made Al Gav ha'Kodesh, and unlike R. Yehoshua [who says that Chulin Al Taharas ha'Kodesh are like regular Chulin].

(R. Ze'irah citing R. Yosa citing R. Yochanan citing R. Yanai citing Rebbi): One who eats a Shelishi of Kodesh, his body is disqualified from eating Kodesh.

Question: Does our Mishnah not teach this? [All agree that one who eats a] Shelishi, he becomes a Sheni for Kodesh!

Answer: The Mishnah discusses actual Kodesh. [Rebbi] comes to teach a bigger Chidush. He is forbidden even Chulin made Al Gav ha'Kodesh. (The Mishnah concludes "b'Chulin made Al Taharas Terumah.'' One might have thought that Al Taharas ha'Kodesh is different, for Batlah Daito Etzel Kol Adam.)

Question (R. Bun bar Chiyah, in front of R. Ze'irah): A Mishnah teaches this! Loaves of Kodesh [touching each other in a line], are in cavities with Kodesh water (i.e. Al Taharas ha'Kodesh. If a Sheretz touched one loaf, all are Tamei. Only four should be Tamei! Rather, we must say that the water is like Kodesh itself, so it becomes a Rishon and makes the loaf a Sheni. We explained this like HA'GAON RAV C. KANIEVSKY, SHLITA.)

Answer (R. Ze'irah): Does it upset you if [Rebbi] comes to teach that [even] liquid in his mouth is like a Kodesh liquid?! (PNEI MOSHE)

(R. Ze'irah): Just like you say there that they made someone Tahor for Chatas like Mei Chatas and Efer Chatas (whatever disqualifies the latter, disqualifies someone Tahor for Chatas), here they made liquid in his mouth like a Kodesh liquid.

(R. Ze'irah): R. Yosa cited R. Yochanan citing R. Yanai, but we do not know if it was in the name of Rebbi. [We can infer from] Mishnayos support [for Rebbi], or refutation [of him];

[We can infer] refutation - [one who eats a] Shelishi, he is a Sheni for Kodesh, but not a Sheni for Terumah. [This is for eating Chulin] Al Taharas Terumah, but for Chulin Al Taharas ha'Kodesh, his body does not become a Sheni for ha'Kodesh.

[We can infer] support - a Shelishi of Terumah is Metamei liquids of Kodesh and disqualifies Kodesh food made Al Taharas ha'Kodesh, but if it was made Al Taharas Terumah, it is Metamei two foods and disqualifies one (i.e. makes a Sheni, which then makes a Shelishi and Revi'i) of Kodesh.

(Beraisa - R. Yosi) Question: What is the source for a Revi'i of Kodesh, that it is Pasul?

A Kal v'Chomer teaches this! A Mechusar Kipurim does not disqualify Terumah, but he disqualifies Kodesh. A Shelishi, which is Pasul for Terumah, all the more so he should disqualify Kodesh (make it a Revi'i)!

We learned a Shelishi from a verse (this is brought below), and a Revi'i from a Kal v'Chomer.

Question (R. Yochanan): Food that comes due to (touched) a Tevul Yom refutes this! It is Pasul for (i.e. forbidden if it is) Terumah, but it does not disqualify Kodesh!

(R. Chananyah citing R. Yochanan): R. Yosi's teaching is like R. Akiva his Rebbi. Just like R. Akiva said there [any liquid that is drunk in any Kli] "Yitma'' - Yetamei (if the Kli was a Rishon, the liquid is a Sheni and it can be Metamei, i.e. make a Shelishi) mid'Oraisa, so R. Yosi says here Yitma - Yetamei, mid'Oraisa.

(R. Avahu citing R. Yosi ben Chaninah): R. Yosi does not need this Kal v'Chomer. R. Yosi expounds verses;

"Veha'Basar Asher Yiga'' - this is a Sheni, which touched a Rishon. "B'Chol Tamei'' - this is a Shelishi, which touched a Sheni. "Lo Yochal'' - the final Tamei (a Revi'i, which touched the Shelishi) will not be eaten.

Question: This [Drashah of Yitma] refers to food that became Tamei from the airspace of a Kli Cheres that became Tamei through a Sheretz. What is the source for food that became Tamei [directly] through a Sheretz?

Answer: A Kal v'Chomer teaches this! Kelim that do not receive Tum'ah from the airspace of a Kli Cheres, if they became Tamei through a Sheretz, they become Tamei like a Sheretz to be Metamei food;

Food itself that became Tamei through a Sheretz, all the more so it becomes Tamei like a Sheretz to be Metamei food!

Question: Until now is like R. Akiva. According to R. Yishmael [what is the source]?

Answer (Beraisa - R. Yishmael) Question: "Veha'Basar Asher Yiga b'Chol Tamei'' - this is a Rishon, which touched a Tamei. "Lo Yochal'' includes a Sheni. What is the source for a Shelishi of Terumah?

Answer: A Tevul Yom does not disqualify Chulin, but he disqualifies Terumah. A Sheni, who disqualifies Chulin, all the more so he should disqualify Terumah!

Question: What is [his] source for a Revi'i in Kodesh?

A Kal v'Chomer teaches this! A Mechusar Kipurim does not disqualify Terumah, but he disqualifies Kodesh. A Shelishi, which is Pasul for Terumah, all the more so it should disqualify Kodesh (make it a Revi'i)!

Conclusion: We learned a Rishon and a Sheni from a verse, and a Shelishis from a Kal v'Chomer, and a Revi'i from a Kal v'Chomer.

A dry hand is Metamei the other for Kodesh, but not for Terumah. Rebbi says so;

R. Yosi bei R. Yehudah says, it is to be Posel in Kodesh.

Question: What does it mean that Rebbi holds like R. Yehoshua?

Answer (Mishnah): Anything that disqualifies Terumah is Metamei the hands to be Sheniyos. One hand is Metamei the other. R. Yehoshua says so.

R. Yehoshua says a bigger [stringency] than Rebbi. Rebbi said about Kodesh, and R. Yehoshua said about Terumah. Rebbi says so.

(Reish Lakish): We learned [that one hand is Metamei] only its colleague (the same person's other hand), but not another's [hand].

(R. Yochanan): [It is Metamei] even another [person's].

(R. Yirmeyah citing R. Ami citing R. Yochanan): Even a loaf [it is Metamei, i.e. makes it a Sheni].

R. Yochanan retracted from this;

What did he say after retracting? He said only that it disqualifies a loaf, for anything that disqualifies Terumah is Metamei the hands to be Sheniyos;

To be Metamei a loaf, all agree that [the hand] is not Metamei, because a Sheni does not make a Sheni. (We explained this like SHA'AREI TORAS ERETZ YISRAEL.)
