Question: (A Mishnah teaches that) mixtures including Isurei ha'Na'ah are forbidden even to a person. All the more so they are Pesulim for Korbanos!

(Mishnah #2): The following are forbidden, and any amount forbids a mixture:

Yayin Nesech (wine that was offered to idolatry), idolatry...

Answer: Both Mishnayos are needed:

If we only had Mishnah #2, one might have thought that a mixture of Chulin is forbidden, but we are not stringent to forbid a mixture of Kodshim;

If we only had our Mishnah, one might have thought that a mixture is forbidden only to the Mizbe'ach, for it is repulsive (to offer an animal that really was Pasul), but Isurei ha'Na'ah are Batel to allow people to benefit from them!

Question: Forbidden animals should be Batel amidst a majority of Heter!

Suggestion: Perhaps they are not Batel because they are important.

Partial rejection: We could say so only according to Reish Lakish, who says that the text in the Mishnah (below) is 'everything that is normally counted' (even things that are only sometimes sold by number. People often sell animals by number, therefore, they are important, and they are never Batel);

However, R. Yochanan holds that the text says 'what is normally counted' (i.e. only what is always sold by number. People sometimes sell a herd without counting it, therefore, animals are not important, and they can be Batel.) How can he answer?

(Mishnah): Bundles of clover of Kilai ha'Kerem (other species planted with grape pits or near vines) must be burned;

R. Meir says, if they became mixed with other bundles (of Heter), (and those became mixed with other bundles - some delete this from the text), all must be burned;

Chachamim say, if there is at least 200 times as much Heter as Isur, the Isur is Batel, and they are permitted;

R. Meir says, everything that is normally counted is Mekadesh (forbids a mixture and is never Batel);

Chachamim say, only six things are Mekadesh - nuts of Parech (a place; Aruch - they are so soft that they can be Nifrach (crushed) by hand), pomegranates of Badan, sealed barrels, stalks of spinach or cabbage, and Yevanis gourds;

R. Akiva adds a seventh thing that is Mekadesh - loaves of a Ba'al ha'Bayis (i.e. not of a professional baker);

Some of these could be forbidden due to Orlah, and the others can be forbidden due to Kilai ha'Kerem.

(R. Yochanan): The text is 'R. Meir says, 'what is normally counted';

(Reish Lakish): The text is 'everything that is normally counted.'

Repetition of question: We understand according to Reish Lakish, but how can we answer according to R. Yochanan?
