(Mishnah): One who eats a k'Zayis of Matzah [of these five grains] was Yotzei the Mitzvah. [One who eats from them] a k'Zayis of Chametz is Chayav Kares.

If one of [these grains] became mixed with any species, [one who eats it] transgresses [a Lav] during Pesach.

If one vowed from bread and from grain, he is forbidden them. R. Meir says so;

Chachamim say, one who vowed from Degen is forbidden only them. (R. Meir forbids anything that is piled up in the field.)

[These five grains] are obligated in Chalah and in Ma'aseros.

(Gemara - R. Yakov bar Zavdi) Inference: (Our Mishnah discusses even a mixture of the grains; one is Yotzei or liable for a k'Zayis, for each species is not Batel in the others.) This teaches that one is lashed mid'Oraisa for their Chalah (of a mixture of them, unlike Reish Lakish said in Halachah 1)!

Rebuttal #1 (R. Yirmeyah citing R. Chiya bar Bari): The case is, he ate a k'Zayis of this species and a k'Zayis of this. (Neither is the majority, so there is no Bitul. Likewise, Chalah applies to equal amounts of two grains mixed together. This is how MASHBI'ACH explains Rebuttal #3.)

Rebuttal #2 (R. Yosi): You can even say that he ate a k'Zayis of all of them (mixed together. Chametz) is different, for all of them are [forbidden] due to Chametz (they are like one species).

Question: R. Yosi contradicts himself! There (in Halachah 1), he said that [even R. Yochanan can agree that] two matters [of Heter] are the majority over one, and they are Mevatel it, and here he says so?!

Rebuttal #3 (R. Yosi bei R. Bun): In our Mishnah, he ate a k'Zayis of this or a k'Zayis of this (R. YOM TOV ALGAZI. Perhaps he rejects Rebuttal #1, for he holds that Iy Efshar Letzamtzem. - PF)

Question: (R. Meir said that if one vowed from bread and from grain, he is forbidden the five grains; Chachamim say, one who vowed from Degen is forbidden only them.) If one vowed from bread and from grain, is he forbidden everything, according to Rabanan?!

Answer (R. Chiya citing R. Yochanan): [Chachamim argue only about the inference from R. Meir, that only one who vowed from bread and from grain is forbidden only the five grains. They add that also] one who vowed from Degen is forbidden only them.

Question: What is the case?

Suggestion: He said 'bread of the Torah.'

Rejection: If so, even one who says 'grain of the Torah' should be forbidden everything, for it says "u'Sevu'as ha'Karem"! (

Suggestion: He said 'bread' Stam (without specifying).

Rejection: The only thing called 'bread' Stam is wheat and barley!

Answer (R. Yosah): I established this in a place where they eat bread of everything (ROSH). The only thing called 'bread' Stam is [from] the five grains.
