Zevachim 31b

הָא לֶאֱכוֹל וְלֶאֱכוֹל דּוּמְיָא דְּלֶאֱכוֹל וּלְהַקְטִיר, וְהֵיכִי דָּמֵי – בִּשְׁנֵי בְּנֵי אָדָם; מִצְטָרֵף! שְׁמַע מִינַּהּ.

It can be inferred that if one had intent to eat and to eat in a manner similar to a case of intent to eat half an olive-bulk and to burn half an olive-bulk; Abaye interjects: And what are the circumstances of such a case? It is a case with two people, i.e., where each one will consume half an olive-bulk. Abaye continues with the conclusion of his statement: Then the two halves join together. The Gemara concludes: Learn from it that this is so.

בָּעֵי רָבָא: חִישֵּׁב לֶאֱכוֹל כְּזַיִת בְּיָתֵר מִכְּדֵי אֲכִילַת פְּרָס, מַהוּ? לַאֲכִילַת גָּבוֹהַּ מְדַמֵּינַן לֵיהּ, אוֹ לַאֲכִילַת הֶדְיוֹט מְדַמֵּינַן לֵיהּ?

Rava raises a dilemma: If one had intent to eat an olive-bulk in more than the period of time it takes to eat a half-loaf of bread, what is the halakha ? Do we equate the consumption of offerings to the consumption of the Most High, i.e., the burning of offerings on the altar, for which there is no maximum allotted time? Or do we equate it to the consumption of an ordinary person, for whom consumption slower than this rate is not considered eating?

אָמַר אַבָּיֵי, תָּא שְׁמַע: לֶאֱכוֹל כַּחֲצִי זַיִת וּלְהַקְטִיר כַּחֲצִי זַיִת – כָּשֵׁר, שֶׁאֵין אֲכִילָה וְהַקְטָרָה מִצְטָרְפִין. טַעְמָא דְּלֶאֱכוֹל וּלְהַקְטִיר, הָא לֶאֱכוֹל וְלֶאֱכוֹל – מִצְטָרֵף; וְהָא הַקְטָרָה בְּיוֹתֵר מִכְּדֵי אֲכִילַת פְּרָס הוּא!

Abaye said: Come and hear a proof from the mishna: If his intent was to eat half an olive-bulk and to burn half an olive-bulk not at the appropriate time or in the appropriate area, the offering is fit because eating and burning do not join together. One may infer that the reason the offering is fit is that he had intent to eat and to burn the offering. But if he had intent to eat half an olive-bulk at the normal rate and to eat half an olive-bulk in the time it takes to burn half an olive-bulk, the two would join together. But the burning of an olive-bulk of an offering can take more than the time it takes to eat a half-loaf of bread. It therefore seems that there is no upper limit on the time in which one is considered to have consumed an offering.

דִּלְמָא בְּהֶיסֵּק גָּדוֹל.

The Gemara rejects the proof: Perhaps the mishna is referring to intent to burn half an olive-bulk in a large fire, which can consume it in the time it takes to eat a half-loaf of bread. Accordingly, one may draw the inference only with regard to a case where his intent was to consume the halves of an olive-bulk within this time.

לֶאֱכוֹל כַּחֲצִי זַיִת וּלְהַקְטִיר כַּחֲצִי זַיִת – כָּשֵׁר. טַעְמָא דְּלֶאֱכוֹל וּלְהַקְטִיר, הָא לֶאֱכוֹל וְלֶאֱכוֹל דָּבָר שֶׁאֵין דַּרְכּוֹ לֶאֱכוֹל – מִצְטָרֵף;

§ The mishna teaches: If one slaughtered the animal with intent to eat half an olive-bulk and to burn half an olive-bulk not at the appropriate time or in the appropriate area, the offering is fit. The Gemara infers: The reason that the two halves of an olive-bulk do not join together is because his intent was to eat half an olive-bulk and to burn half an olive-bulk. But if his intent was to eat half an olive-bulk of the meat and to eat half an olive-bulk of an item whose typical manner is such that one does not partake of it, then the halves do join together and disqualify the offering, as both intentions concern eating.

הָא קָתָנֵי רֵישָׁא: לֶאֱכוֹל אֶת שֶׁדַּרְכּוֹ לֶאֱכוֹל – מִצְטָרֵף; אֶת שֶׁדַּרְכּוֹ לֶאֱכוֹל אִין, שֶׁאֵין דַּרְכּוֹ לָא!

The Gemara notes an apparent contradiction: But the first clause of the mishna teaches: If one’s intent was to partake of an item whose typical manner is such that one partakes of it, beyond its designated time, his intent joins together to disqualify the offering. One can infer that only if his intent was to partake of an item whose typical manner is such that one partakes of it, does his intent join together, but if his intent was to partake of an item whose typical manner is such that one does not partake of it, then it does not join together.

אָמַר רַבִּי יִרְמְיָה: הָא מַנִּי – רַבִּי אֱלִיעֶזֶר הִיא, דְּאָמַר: מְחַשְּׁבִין מֵאֲכִילַת אָדָם לַאֲכִילַת מִזְבֵּחַ, וּמֵאֲכִילַת מִזְבֵּחַ לַאֲכִילַת אָדָם. דִּתְנַן: הַשּׁוֹחֵט אֶת הַזֶּבַח לֶאֱכוֹל דָּבָר שֶׁאֵין דַּרְכּוֹ לֶאֱכוֹל, וּלְהַקְטִיר דָּבָר שֶׁאֵין דַּרְכּוֹ לְהַקְטִיר – כָּשֵׁר. וְרַבִּי אֱלִיעֶזֶר פּוֹסֵל.

Rabbi Yirmeya says: In accordance with whose opinion is this latter clause? It is in accordance with the opinion of Rabbi Eliezer, who says: One can have intent to shift an item’s consumption from consumption by a person to consumption by the altar, or from consumption by the altar to consumption by a person. As we learned in another mishna (35a): In the case of one who slaughters the offering with intent to partake of an item whose typical manner is such that one does not partake of it, or to burn an item whose typical manner is such that one does not burn it on the altar, beyond its designated time or outside its designated area, the offering is fit, and Rabbi Eliezer deems it unfit.

אַבָּיֵי אָמַר: אֲפִילּוּ תֵּימָא רַבָּנַן – וְלָא תֵּימָא: הָא לֶאֱכוֹל וְלֶאֱכוֹל דָּבָר שֶׁאֵין דַּרְכּוֹ לֶאֱכוֹל, אֶלָּא אֵימָא: הָא לֶאֱכוֹל וְלֶאֱכוֹל דָּבָר שֶׁדַּרְכּוֹ לֶאֱכוֹל.

Abaye says: You may even say that the latter clause is in accordance with the opinion of the Rabbis. And do not say that one should infer from the mishna that if his intent was to eat half an olive-bulk of an item normally consumed and to eat half an olive-bulk of an item whose typical manner is such that one does not partake of it, then the offering is disqualified. Rather, say that one infers that if his intent was to eat half an olive-bulk and to eat another half an olive-bulk, both halves from an item whose typical manner is such that one partakes of it, then the halves join together to disqualify the offering.

מַאי קָא מַשְׁמַע לַן? אִי דָּבָר שֶׁדַּרְכּוֹ לֶאֱכוֹל קָא מַשְׁמַע לַן – מֵרֵישָׁא שְׁמַע מִינַּהּ: כַּחֲצִי זַיִת בַּחוּץ כַּחֲצִי זַיִת לְמָחָר – פָּסוּל; הָא כַּחֲצִי זַיִת לְמָחָר – פִּיגּוּל!

The Gemara asks: If so, what is this latter clause teaching us? If it teaches us that two half olive-bulks from an item whose typical manner is such that one partakes of it, join together, one can already learn this from the first clause of the mishna: If one has intent to consume half an olive-bulk outside its designated area and half an olive-bulk the next day, the offering is disqualified. One can infer that if his intent was to eat the first half an olive-bulk the next day, the offering would be rendered piggul .

אֶלָּא אִי לֶאֱכוֹל וּלְהַקְטִיר – מִדּוּקְיָא דְּרֵישָׁא שְׁמַע מִינַּהּ: לֶאֱכוֹל דָּבָר שֶׁדַּרְכּוֹ לֶאֱכוֹל – אִין, שֶׁאֵין דַּרְכּוֹ לֶאֱכוֹל – לֹא;

But if one will say that this term teaches its literal meaning, that intentions to eat and to burn two halves of an olive-bulk do not join together, one can already learn this from the inference drawn above from the first clause of the mishna, namely that intent to partake of an item whose typical manner is such that one partakes of it does disqualify the offering, but intent to partake of an item whose typical manner is such that one does not partake of it does not. By extension, intent to consume half an olive-bulk of such an item does not join to disqualify the offering.

הַשְׁתָּא וּמָה לֶאֱכוֹל וְלֶאֱכוֹל דָּבָר שֶׁאֵין דַּרְכּוֹ לֶאֱכוֹל – לָא מִצְטָרֵף, לֶאֱכוֹל וּלְהַקְטִיר מִיבְּעֵי?!

Now, consider the following: And just as if when one has intent to partake of an item normally eaten and to partake of an item whose typical manner is such that one does not partake of it, his intentions do not join together, even though both intentions concern consumption, is it necessary for the mishna to teach that intentions to consume and to burn do not join together? The last clause therefore seems unnecessary.

לֶאֱכוֹל וּלְהַקְטִיר אִיצְטְרִיךְ; סָלְקָא דַּעְתָּךְ אָמֵינָא: הָתָם הוּא דְּלָאו כִּי אוֹרְחֵיהּ קָא מְחַשֵּׁב; אֲבָל הָכָא, דִּבְהַאי כִּי אוֹרְחֵיהּ וּבְהַאי כִּי אוֹרְחֵיהּ – אֵימָא לִיצְטָרֵף; קָא מַשְׁמַע לַן.

The Gemara responds: It was necessary for the mishna to explicitly address the case where one had intent to eat and to burn, as it might enter your mind to say that it is only there, where one’s intentions are referring solely to consumption, that they do not join together, since he has intent to act in a way that is not consistent with its typical manner and consume an item not normally consumed. But here, where his intent is to both eat and burn the offering, such that with regard to this half he intends to act in a way consistent with its typical manner, and with regard to that half he intends to act in a way consistent with its typical manner, one might say that they should join together. Therefore, the mishna teaches us that intentions to eat and to burn do not join together.

הֲדַרַן עֲלָךְ כׇּל הַזְּבָחִים שֶׁקִּבְּלוּ דָּמָן

MISHNA: With regard to all those who are unfit for Temple service who slaughtered an offering, their slaughter is valid, as the slaughter of an offering is valid ab initio when performed even by non-priests, by women, by Canaanite slaves, and by ritually impure individuals. And this is the halakha even with regard to offerings of the most sacred order, provided that the ritually impure will not touch the flesh of the slaughtered animal, thereby rendering it impure. Therefore, these unfit individuals can disqualify the offering with prohibited intent, e.g., if one of them intended to partake of the offering beyond its designated time or outside its designated area.

מַתְנִי׳ כׇּל הַפְּסוּלִין שֶׁשָּׁחֲטוּ – שְׁחִיטָתָן כְּשֵׁרָה, שֶׁהַשְּׁחִיטָה כְּשֵׁרָה בְּזָרִים וּבְנָשִׁים וּבַעֲבָדִים וּבִטְמֵאִים. וַאֲפִילּוּ בְּקׇדְשֵׁי קָדָשִׁים, וּבִלְבַד שֶׁלֹּא יִהְיוּ טְמֵאִים נוֹגְעִין בַּבָּשָׂר. לְפִיכָךְ הֵן פּוֹסְלִין בְּמַחְשָׁבָה.
