1) JOINING ONE HALF-"ZAYIS" TO ANOTHER

(a) (Rava): If one intended to eat half a k'Zayis tomorrow, half a k'Zayis b'Chutz, and half a k'Zayis tomorrow, the first intention Chutz li'Zmano (which initially was joining Chutz li'Mkomo to Posel without Kares) is aroused to join the latter Chutz li'Zmano to make Pigul with Kares.
(b) (Rav Hamnuna): These are mixed intentions.
(c) Support (Rava, for himself - Mishnah): If k'Beitzah (an egg's worth) of a food that is a Rishon (first-degree Tum'ah) was mixed with k'Beitzah of a food that is a Sheni (second-degree Tum'ah), the mixture is (Metamei like) a Rishon (it makes a Sheni); if the mixture was split into two parts, each a k'Beitzah, each is a Sheni (makes a Shelishi) (each part has only half a k'Beitzah of a Rishon, only a k'Beitzah is Metamei);

1. Inference: If the parts were reunited, the mixture is a Rishon.
2. Question: What is the source to say this?
3. Answer (end of the Mishnah): If each part fell by itself on a Terumah loaf, it was Posel it (made it a Shelishi); if they fell together (touched it at the same time), they make it a Sheni.

(d) Version #1 - Rashi - Rejection (Rav Hamnuna): There is different, for there was a complete quantity (from the beginning, therefore it is aroused again - in Rava's case of Pigul, initially there was not k'Zayis Chutz li'Zmano).
(e) Version #2 - R. Tam - Rejection (Rav Hamnuna): There is different, for there is a complete quantity for the Sheni to join with - in Rava's case, since there is not a full k'Zayis Chutz li'Mkomo, it remains combined with Chutz li'Zmano to Posel, the half k'Zeisim of Chutz li'Zmano do not combine with each other.
(f) Support (Rav Hamnuna, for himself - Mishnah): A Rishon and a Sheni or Shelishi (each less than k'Beitzah) join together to Metamei like the less Tamei one.

1. Inference: Even if it joined with more of a Rishon (completing the quantity of a k'Beitzah), it is not a Rishon.

(g) Rejection: Perhaps the Mishnah is only if the quantity was not completed.
(h) (Rav Dimi citing Bar Kapara): Half a k'Zayis Chutz li'Mkomo, half a k'Zayis Chutz li'Zmano, half a k'Zayis Chutz li'Zmano - the half k'Zayis Chutz li'Mkomo does not take effect, the k'Zayis of Chutz li'Zmano makes Pigul.
(i) (Ravin citing Bar Kapara): Half a k'Zayis Chutz li'Zmano, half a k'Zayis Chutz li'Zmano, half a k'Zayis Chutz li'Mkomo - the half k'Zayis Chutz li'Mkomo does not take effect, the k'Zayis of Chutz li'Zmano makes Pigul.
(j) (Rav Ashi citing Bar Kapara): Half a k'Zayis Chutz li'Zmano, and a k'Zayis, half is Chutz li'Mkomo, half is Chutz li'Zmano - the half k'Zayis Chutz li'Mkomo does not take effect, the k'Zayis of Chutz li'Zmano makes Pigul.

(a) (R. Yanai): If one intended to feed a k'Zayis to a dog tomorrow, it is Pigul - "V'Es Izevel Yochlu ha'Kelavim".
(b) Objection (R. Ami): If so, if one intended to burn a k'Zayis, it should be Pigul - "Te'achlehu Esh"!

1. Suggestion: Perhaps that is true!
2. Rejection (Mishnah): (If he intended) to eat half a k'Zayis (Chutz li'Mkomo or Chutz li'Zmano) and Lehaktir half a k'Zayis, it is Kosher, because eating and burning do not join.

(c) Answer: If he said that the fire will 'Ochel' (a language of eating), it joins with human eating!

1. The Mishnah is when he said 'Lehaktir' (to burn).

(d) Question (Rav Asi): If he intended to feed a k'Zayis to two people (Chutz), what is the law?

1. If intention for a k'Zayis is the criterion, he did so;
2. If he must intend for a person to eat a k'Zayis, he did not.

(e) Answer (Abaye - Mishnah): To eat half a k'Zayis and Lehaktir half a k'Zayis, it is Kosher, because eating and burning do not join.

1. Inference: In a similar case of eating and eating, i.e. two different people, they would join!

(f) Question (Rava): If one intended to eat a k'Zayis (Chutz) over a period of time more than is needed to eat a half loaf, what is the law?

1. Do we learn from consumption of the Mizbe'ach (which is also slow), or of people (this is not considered eating regarding other Mitzvos)?

(g) Answer (Abaye - Mishnah): To eat half a k'Zayis and Lehaktir half a k'Zayis, it is Kosher, because eating and burning do not join.

1. Inference: In a similar case of eating and eating, they would join;
2. Haktarah of a k'Zayis takes more than the time to eat a half loaf - a similar case of eating joins to make Pigul!

(h) Rejection: Perhaps the Mishnah refers to a big fire on the Mizbe'ach (a k'Zayis burns in less than the time to eat a half loaf).
(i) Inference: The Mishnah says that eating and burning do not join - if the same things burned would be eaten instead, they would join, even though what is fit for the Mizbe'ach is not fit for people!
(j) Contradiction (beginning of the Mishnah): To eat something normally eaten.

1. Inference: Things not normally eaten do not join for Pigul!

(k) Answer #1 (R. Yirmeyah): The end of the Mishnah is R. Eliezer, who says that intent for a person (or the Mizbe'ach) to 'eat' something fit for the Mizbe'ach (or people) is intention.

1. (Mishnah): If one slaughtered a Korban with intent to eat (or burn) (Chutz li'Zmano or Chutz li'Mkomo) something which is not normally eaten (or burned), it is Kosher;
2. R. Eliezer says, it is Pasul.

(l) Answer #2 (Abaye): The end of the Mishnah can be Chachamim; 1

. Do not infer that eating something not normally eaten joins for Pigul, rather, eating something normally eaten joins.

(m) Question: What is the Chidush?

1. It cannot teach that half a k'Zayis Chutz li'Mkomo and half a k'Zayis Chutz li'Zmano join to Posel - a previous clause of Mishnah teaches this explicitly!
2. It cannot teach that intention to eat half a k'Zayis and Lehaktir half a k'Zayis join - we infer otherwise from the beginning of the Mishnah!

i. (Beginning of the Mishnah): To eat something normally eaten;
ii. Inference: Something not normally eaten does not join for Pigul.

3. If intention to eat half a k'Zayis (of meat) and to eat half a k'Zayis of Eimurim (which are not normally eaten) do not join, all the more so intentions to eat and burn them do not join!

(n) Answer: No - intentions to eat both do not join because the latter is abnormal, but intention to eat half a k'Zayis of meat could join intent to burn half a k'Zayis of Eimurim, since both of these are normal;

1. Therefore, the Mishnah must teach that they do not join.

3) IF "PESULIM" SLAUGHTERED

(a) (Mishnah): If any of the following Pesulim (i.e. for other Avodos) slaughtered, it is Kosher, even Kodshei Kodoshim - a Zar, a woman, a slave, or a Tamei (person).

1. The Tamei must be careful not to touch the meat.

(b) Because the slaughter is valid, if a Pasul slaughtered with improper intention (Chutz li'Zmano or Chutz li'Mkomo), this disqualifies the Korban.
