Text Snapshot

The Mishnah on Menachot 12a lays down the foundational principles for piggul liability:

הרי זה פיגול וחייבין עליו כרת. זה הכלל: כל המוציא את הקומץ, או מניחו בכלי, או מוליכו, או ששורפו, לאכול דבר שדרכו לאכול, או להקטיר דבר שדרכו להקטיר, חוץ למקומו – פסול ואין בו כרת. למעלה מזמנו – פיגול וחייבים עליו כרת, ובלבד שהיה ההיתר הוקרב כמצוותו. כיצד ההיתר הוקרב כמצוותו? הוציא את הקומץ בשתיקה, והניחו בכלי, והוליכו, ושרפו, לאכול למעלה מזמנו; או שהוציא את הקומץ למעלה מזמנו, והניחו בכלי, והוליכו, ושרפו בשתיקה...

רַבִּי יְהוּדָה אוֹמֵר: זֶה הַכְּלָל: אִם קָדְמָה מַחֲשֶׁבֶת זְמַן לְמַחֲשֶׁבֶת מָקוֹם – פִּיגּוּל וְחַיָּבִין עָלָיו כָּרֵת. וְאִם קָדְמָה מַחֲשֶׁבֶת מָקוֹם לְמַחֲשֶׁבֶת זְמַן – פָּסוּל וְאֵין בּוֹ כָּרֵת. וַחֲכָמִים אוֹמְרִים: בֵּין כָּךְ וּבֵין כָּךְ – פָּסוּל וְאֵין בּוֹ כָּרֵת.

"This is piggul and one is liable to receive karet for partaking of the remainder of that meal offering... This is the principle: In the case of anyone who removes the handful, or places the handful in the vessel, or who conveys the vessel with the handful to the altar, or who burns the handful on the altar, with the intent to partake of an item whose typical manner is such that one partakes of it, e.g., the remainder, or to burn an item whose typical manner is such that one burns it on the altar, e.g., the handful or the frankincense, outside its designated area, the meal offering is unfit but there is no liability for karet. If his intent was to do so beyond its designated time, the offering is piggul and one is liable to receive karet on account of it, provided that the permitting factor, i.e., the handful, was sacrificed in accordance with its mitzva. How is the permitting factor considered to have been sacrificed in accordance with its mitzva? If one removed the handful in silence... and burned the handful on the altar, with the intent to partake of the remainder beyond its designated time; or...

Rabbi Yehuda says: This is the principle: If the intent with regard to the time preceded the intent with regard to the area, the offering is piggul and one is liable to receive karet on account of it. If the intent with regard to the area preceded the intent with regard to the time, the offering is unfit but there is no liability for karet. And the Rabbis say: In both this case... and that case... the offering is unfit but there is no liability for karet." (Menachot 12a)

Dikduk/Leshon Nuance:

  • The phrase "זה הכלל" (this is the principle) signals a foundational rule, often followed by specific applications or exceptions. Here, it introduces the core distinction between machshevet zeman (intent beyond its time) which leads to piggul, and machshevet makom (intent outside its area) which leads only to pesul.
  • "ובלבד שהיה ההיתר הוקרב כמצוותו" (provided that the permitting factor was sacrificed in accordance with its mitzva): This crucial clause introduces a condition for piggul to apply. The subsequent examples clarify what "כמצוותו" entails, primarily distinguishing between machshevet zeman and machshevet makom at different avodot. If any avodah (e.g., kemitzah, netinah, holachah, haktarah) is performed with machshevet makom, it automatically renders the korban pasul and prevents piggul from ever taking effect.

Readings

Rashi: The Root of Karet for Piggul

Rashi, in his commentary on the opening Mishnah, elucidates the source of karet liability for consuming piggul shiyarei mincha. He connects it to the general principle of piggul for korbanot and specifically references a gezeirah shavah:

פיגול וחייבים עליו כרת – האוכל משירי מנחה דכתיב בחוץ לזמנו (ויקרא ז׳:י״ח) עונה תשא וכתיב בנותר ואוכליו עונו ישא (שם יט) מה להלן כתיב ונכרתה אף כאן האוכלו בכרת והך ג"ש בפ"ק דכריתות (דף ה.): (Rashi on Menachot 12a s.v. פיגול וחייבין עליו כרת)

Rashi explains that the karet for piggul of shiyarei mincha (remainder of the meal offering) derives from a gezeirah shavah (verbal analogy) between Vayikra 7:18 concerning piggul ("עונה תשא") and Vayikra 19:8 concerning notar (leftover meat) ("ואוכליו עונו ישא"). Since notar explicitly states "ונכרתה" (he shall be cut off), the same applies to piggul. This brief note underscores the severity of piggul, not just as a pesul but as an act incurring divine punishment.

Steinsaltz: Clarifying the Piggul Liability

Steinsaltz's commentary provides a concise restatement, confirming the Mishnah's direct assertion:

הרי זה פיגול, וחייבין עליו כרת על אכילה משיירי המנחה הזו. (Steinsaltz on Menachot 12a:1 s.v. הרי זה פיגול)

Steinsaltz essentially reiterates that the karet liability applies specifically to eating the remainder of the mincha that has become piggul. This serves as a straightforward explanation, reinforcing the direct reading of the Mishnah's consequence.

Rashbam & Rashi: The Rav Huna/Rava Debate on Chesaron and Meilah

The Gemara's discussion about cheseron (lacking measure) introduces a profound conceptual debate between Rav Huna and Rava, which hinges on the understanding of pesul and its interaction with avodot. Both Rashbam and Rashi provide essential insights into this sugya.

The Gemara asks whether burning the kometz (handful) is effective in rendering a mincha with a cheseron (lacking remainder) as piggul, or in removing it from meilah. This question is framed through the lens of Rabbi Akiva's opinion regarding yotzei (an offering that left the Temple courtyard).

Rashbam states:

אפי' לר' עקיבא דאמר זריקה מועלת - דתנן (שם דף ו:) בשר קדשי קדשים וכו' ר"ע אומר אין מועלין בו וחייבין עליו משום פיגול ונותר וטמא דזריקת דם מועלת ליה לקבוע בפיגול ולהוציאתו מידי מעילה אע"פ שאינה מתירתו באכילה: (Rashbam on Menachot 12a s.v. אפי' לר' עקיבא דאמר זריקה מועלת)

Rashbam refers to Zevachim 6b (or Meilah 7a as per Rashi's parallel) where R' Akiva maintains that zrikas hadam (sprinkling of blood) is effective for a yotzei korban – it removes it from meilah and can establish piggul liability, even though the yotzei meat itself remains forbidden for consumption. Rashbam emphasizes that zrikah "מועלת ליה לקבוע בפיגול ולהוציאתו מידי מעילה אע"פ שאינה מתירתו באכילה" (is effective for it to establish piggul and to remove it from meilah, even though it does not permit it for consumption). This highlights R' Akiva's chiddush: an avodah can have some effect even on a pasul item, as long as the pesul isn't inherent to the avodah itself.

Rashi further clarifies R' Akiva's position:

אפילו ר"ע - דאמר בפ"ק דמעילה (דף ז.) זריקה מועלת ליוצא חוץ לקלעים למיהוי כדבר שיש לו היתר לכהנים ולמיפק מידי אשם מעילות (ר"ע אומר אין מועלין בו) דזריקתו הוציאתו מידי מעילה אע"פ שאינה מתרת באכילה אעפ"כ מועלת לו להוציאו מידי מעילה: (Rashi on Menachot 12a s.v. אפילו ר"ע)

Rashi also points to Meilah 7a, where R' Akiva's opinion is presented. The key is that zrikah functions to give the yotzei meat the status of "a thing that could have been permitted to the priests" (כדבר שיש לו היתר לכהנים), thereby removing it from meilah. The pesul of yotzei is external to the korban itself, a "פסול מחמת דבר אחר" (disqualification due to something else), as the Gemara itself puts it (Menachot 12a).

Tosafot: Distinguishing Yotzei (External Pesul)

Tosafot delve deeper into the nature of yotzei, particularly in the context of the cheseron debate. They consider the nuance of yotzei in relation to meilah and piggul:

ה"מ יוצא דאיתיה בעיניה כו'. הוה מצי למימר ה"מ יוצא מקצתו אבל יוצא כולו לא כדאמרינן בפ"ק דמעילה (דף ו:) והכא כיצא כולו דמי כיון דאסורין באכילה ומיהו פלוגתא היא התם וא"ת למ"ד יצא כולו לא הא דתניא פרק כל שעה (פסחים לד:) נטמא בשר או נפסל או שיצא חוץ לקלעי' ר"א אומר יזרוק פי' דיש דם אע"פ שאין בשר ר' יהושע אומר לא יזרוק פי' דאם אין בשר אין דם ומודה ר' יהושע דאם זרק הורצה על כרחך ביצא כולו דאי נשתייר כזית זורק לכתחילה ומדקאמר אם זרק הורצה ש"מ דזריקה מועלת ליצא כולו ושמא דרבי יהושע עדיפא מדר"ע א"נ לענין הרצאה שאני לרבי יהושע בין לכתחילה בין לדיעבד אפי' ביצא כולו כדאמר בפ' כיצד צולין (פסחים עז:) אבל לעולם לא מיקבע בפיגול ולא נפיק מידי מעילה היכא דיצא כולו מידי דהוה אחסרון לרב הונא: (Tosafot on Menachot 12a s.v. ה"מ יוצא)

Tosafot raises the distinction between yotzei mikztato (partially exited) and yotzei kulo (entirely exited). In Meilah 6b, there is a debate whether zrikah is effective for yotzei kulo. The Gemara in Menachot seems to equate cheseron to yotzei kulo in terms of ineffectiveness for piggul and meilah (according to Rav Huna). Tosafot then brings a baraita from Pesachim 34b where R' Yehoshua agrees bedi'eved (ex post facto) that zrikah is effective for yotzei kulo for hartzah (acceptance). This implies a broader effectiveness of zrikah even for a fully disqualified item. However, Tosafot reconciles this by suggesting that R' Yehoshua's view on hartzah might be distinct, or that even if hartzah occurs, it doesn't necessarily mean the item is removed from meilah or can become piggul. Ultimately, Tosafot aligns with Rav Huna's position that cheseron is an inherent pesul akin to yotzei kulo for rendering zrikah ineffective for piggul and meilah. This demonstrates a sophisticated understanding of how different types of pesul (external vs. internal, partial vs. complete) impact the efficacy of avodot.

Petach Einayim: The Rabbanan's Position and Inter-Sugya Consistency

The Petach Einayim (Rav Yosef Chaim David Azulai) engages with Tosafot's comment on the Mishnah's dispute between Rabbi Yehuda and the Rabbis:

תוס' ד"ה וחכמים אומרים וכו' וא"ת היינו ת"ק וי"ל דאתא למסתם כוותיה דכה"ג משני פרק המפלת. עכ"ל. הרב תי"ט הקשה קושית התוס' הלזו ואסיק בצ"ע וכבר הושג מהרב בית דוד שם דנעלמו ממנו דברי התוס' דהקשו קושיתו ופריקו לה ע"ש. ועוד יש להרגיש על הרב תי"ט דלא זכר דרבינו עובדיה סוף פרק המפלת פירש בפירושו כמ"ש שם בש"ס וחכמים היינו ת"ק ומשום דמסתבר טעמיה דר"י אתא למסתם כת"ק. והרב תי"ט שם זכר סוגיא דהתם והו"ל לתרץ קושיתו בההיא דהמפלת וכמו שתירצו התוס' הכא ע"פ סוגית המפלת: (Petach Einayim on Menachot 12a s.v. תוס' ד"ה וחכמים אומרים)

The Petach Einayim highlights a Tosafot (not explicitly in our Sefaria text, but a known Tosafot on this sugya) that raises a kushya: the Rabbis' opinion ("בין כך ובין כך פסול ואין בו כרת") seems identical to the Tanna Kamma's earlier statement ("חוץ למקומו – פסול ואין בו כרת"). Tosafot resolves this by suggesting the Rabbis' statement comes to stam (state anonymously, implying consensus) in accordance with the Tanna Kamma, as is explained in Perek Hamapeles. The Petach Einayim then critiques a later Acharon, Rav Ti'omim, for struggling with this kushya without referencing Tosafot's terutz from Perek Hamapeles. This demonstrates how later Acharonim engage in critical analysis of prior Rishonim, ensuring consistency across sugyot. The conceptual point is that sometimes the Rabbis' statements aren't necessarily introducing a new chiddush, but rather affirming a previously stated anonymous opinion, especially when it is logically compelling ("דמסתבר טעמיה").

Friction

The Great Divide: Chesaron, Piggul, and Meilah

The most profound kushya in this sugya revolves around the question of whether a korban that suffers from cheseron (a lacking measure, specifically here: the remainder of the mincha being less than a k'zayit) can still become piggul or be removed from meilah by the haktarah (burning) of the kometz. This forms the crux of the Rav Huna-Rava debate.

The Kushya: The Gemara begins with a dilemma: If the remainder of the mincha becomes lacking (e.g., less than a k'zayit) between the kemitzah (removal of handful) and haktarah (burning of handful), yet the kometz is still burned (as per the Tanna who allows this), can this haktarah with improper intent render the mincha piggul, or remove it from meilah?

Rav Huna argues that even according to Rabbi Akiva, who says zrikah (sprinkling of blood) is effective for yotzei (an offering that left the Temple courtyard) to remove meilah and establish piggul, this only applies to yotzei. Why? Because yotzei is a pesul "מחמת דבר אחר" (due to an external factor) and the item itself "איתיה בעיניה" (is still intact). However, cheseron is a pesul "מגויה" (inherent to itself), a fundamental flaw in the korban's integrity. Therefore, for cheseron, haktarah is not effective.

אמר רב הונא: אפילו לרבי עקיבא, דאמר זריקה מועלת ליוצא — הני מילי יוצא, דאיתיה בעיניה, ופסול מחמת דבר אחר. אבל חסרון, דפסול מגויה — אין הקטרה מועלת. (Menachot 12a)

Rava initially counters: On the contrary, even according to Rabbi Eliezer, who says zrikah is not effective for yotzei, that's because yotzei "ליתיה בפנים" (it's not inside the Temple courtyard). But cheseron "איתיה בפנים" (it is inside), so haktarah should be effective. Rava then attempts to prove this from Rabbi Chiyya's version of the Mishnah, which omits "או כזית" (or an olive-bulk) when discussing intent to consume the remainder. Rava suggests this implies the Mishnah deals with a remainder that became a k'zayit after cheseron, yet piggul still applies. Abaye rebuffs Rava's proof, suggesting R' Chiyya's Mishnah follows R' Elazar's view on machshevet shiur (intent regarding a specific measure) from Zevachim 109b, which means one is only liable for the full handful, not just a k'zayit. This kushya highlights the tension between the physical state of the korban and the halachic efficacy of the avodah.

The Best Terutz (and Rava's Retraction): Rava, after his initial proof is refuted, retracts his position based on a baraita concerning Lechem HaPanim (Shewbread):

אמר רבא: הני מילי דאמינא — לא מידי, דתניא: "קֹדֶשׁ קָדָשִׁים הוּא" (ויקרא כד, ט) — לומר שאם נשבר אחת מהן, פסלו כולן. (Menachot 12b) The baraita states that if one Lechem HaPanim loaf breaks (a cheseron), all loaves are disqualified. Rava infers that if one loaf left the Temple (a yotzei), the remaining loaves are still kashrut. Since R' Akiva is the one who says zrikah is effective for yotzei, yet he seemingly agrees here that cheseron disqualifies everything, this implies that even R' Akiva distinguishes between yotzei and cheseron. For cheseron, the haktarah (or burning of frankincense, in the case of Lechem HaPanim) is not effective.

Abaye, however, offers a sophisticated terutz that saves R' Akiva's consistency and refines the distinction:

אמר ליה אביי: מי תניא יצא? דילמא נטמא — אלו כשירות, מ"ט? דחזיתא. אבל יצא — לא חזיתא. ואם כן, דרבי אליעזר היא, דאמר זריקה אינה מועלת ליוצא. ועל כרחך נמי הוה ליה למיתני יצא. ודקא תני נשבר — ה"ק: אפילו נשבר, דאיתיה בפנים — אין הקטרה מועלת לו. אבל לר' עקיבא, דאמר זריקה מועלת ליוצא — אפילו בחסרון, הקטרה מועלת לו. (Menachot 12b)

Abaye rejects Rava's inference from the Lechem HaPanim baraita. He argues that the baraita doesn't necessarily imply yotzei is effective. Perhaps it refers to tum'ah (ritual impurity), where the tzitz (High Priest's headplate) effects acceptance for the tum'ah, but not for yotzei. More importantly, Abaye offers a counter-reading: the baraita specifically mentioning "נשבר" (broken/lacking) comes to teach that even in a case of cheseron b'fanai (lacking but still inside the Temple), haktarah is not effective. This is in line with R' Eliezer. However, Abaye then states his own chiddush: "אבל לר' עקיבא, דאמר זריקה מועלת ליוצא — אפילו בחסרון, הקטרה מועלת לו." (But according to R' Akiva, who says zrikah is effective for yotzei — even for a cheseron, haktarah is effective for it.)

Abaye's final terutz (which is the accepted one to interpret R' Akiva) means that R' Akiva does differentiate:

  1. Yotzei: The item is physically complete but is in the wrong place. Zrikah (or haktarah in mincha) is effective because the pesul is external and the item itself is intact.
  2. Chesaron: The item is physically lacking, an inherent flaw. Haktarah is not effective for piggul or meilah because the very essence of the korban is compromised.

This resolution refines the understanding of "פסול מחמת דבר אחר" (external disqualification) versus "פסול מגויה" (internal disqualification). For R' Akiva, yotzei is "external" because the object itself is whole, merely displaced. Chesaron is "internal" because the object itself is incomplete. Thus, haktarah (or zrikah) cannot complete or validate an inherently lacking korban.

Intertext

1. Zevachim 109b-110a: The Scope of Rabbi Elazar's Liability for "Shiur"

The Gemara on Menachot 12a references Zevachim 109b in Abaye's attempt to refute Rava's proof from R' Chiyya's Mishnah. The Mishnah in Zevachim states:

הַקּוֹמֶץ וְהַלְּבוֹנָה וְהַקְּטוֹרֶת וּמִנְחַת כֹּהֲנִים וּמִנְחַת מָשִׁיחַ וּמִנְחַת נְסָכִים, שֶׁהִקְטִיר מֵהֶן כְּזַיִת בַּחוּץ — חַיָּב. רַבִּי אֶלְעָזָר פּוֹטֵר עַד שֶׁיַּקְטִיר אֶת כּוּלּוֹ. (Zevachim 109b)

This Mishnah establishes a dispute regarding liability for haktarat chochmatz (burning outside the Temple). The Tanna Kamma holds one liable for burning even a k'zayit of these items (handful, frankincense, etc.) outside. Rabbi Elazar, however, exempts liability unless the entire measure (e.g., the whole handful) is burned outside.

This parallel is crucial for understanding Abaye's argument against Rava's initial proof. Rava suggested that R' Chiyya's Mishnah, by omitting "or a k'zayit" from its wording regarding intent for the remainder, implies it's discussing a case where the remainder became a k'zayit due to cheseron, yet piggul still applies. Abaye countered that R' Chiyya's Mishnah follows R' Elazar. If R' Elazar holds that intent for less than the entire handful is not significant enough to cause piggul (or haktarat chochmatz liability), then the omission of "or a k'zayit" is consistent, as intent for a partial amount of the kometz or shiyarayim would not be relevant for piggul according to his approach. This demonstrates the profound interconnectedness of sugyot in determining the underlying principles of Tannaic opinions.

2. Meilah 7a: Rabbi Akiva's Stance on Zrikah and Yotzei

The entire Rav Huna-Rava debate hinges on R' Akiva's opinion regarding zrikah and yotzei, as explicitly referenced by Rashi and Rashbam:

קָדְשֵׁי קָדָשִׁים שֶׁיָּצְאוּ חוּץ לַקְּלָעִים, רַבִּי עֲקִיבָא אוֹמֵר: אֵין מוֹעֲלִין בָּהֶן, וְחַיָּבִין עֲלֵיהֶם מִשּׁוּם פִּיגּוּל, וְנוֹתָר, וְטָמֵא. (Meilah 7a)

This Mishnah in Meilah directly presents R' Akiva's chiddush: a korban kodshei kodashim that yotzei (leaves the Temple courtyard) is not subject to meilah after zrikas hadam, and one is liable for piggul, notar, and tamei if these conditions apply. The implication is that zrikas hadam is effective in removing the korban from its meilah status and establishing piggul, despite the meat itself being forbidden due to yotzei. The Gemara in Menachot grapples with the conceptual basis for this. Rav Huna attributes it to yotzei being "פסול מחמת דבר אחר" (an external disqualification), where the meat remains "איתיה בעיניה" (intact). This distinction allows the avodah (sprinkling) to have some effect. The debate then is whether cheseron (lacking measure) also falls under this rubric. Ultimately, as discussed in the "Friction" section, Abaye's final terutz clarifies that for R' Akiva, cheseron is an internal disqualification, rendering haktarah ineffective for piggul or meilah removal, while yotzei remains an external one, allowing zrikah to have its effect.

Psak/Practice

The principles derived from Menachot 12a regarding piggul are codified extensively in Halacha L'Ma'aseh, particularly in the Rambam's Hilchot Ma'aseh HaKorbanot and Hilchot Pesulei HaMukdashin.

  1. Machshevet Zeman vs. Machshevet Makom: The Mishnah's core distinction is foundational. Rambam rules that only machshevet zeman (intent to consume/burn beyond its designated time) generates piggul and karet. Machshevet makom (intent to consume/burn outside its designated area) only renders the offering pasul, without karet.

    כל שחיטה או קבלה או הולכה או זריקה שהיתה שלא לשמה, ואף על פי שהיתה בזמנה ובמקומה, הרי זו פסולה ואין בה כרת. ואם היתה המחשבה שלא לזמנה, כגון שחיטה ביום ומחשבה לאכול למחר, הרי זו פיגול וחייבין עליה כרת. (Rambam, Hilchot Ma'aseh HaKorbanot 17:1) He then clarifies that if the improper intent was for machshevet makom, it's only pasul: ואם היתה המחשבה חוץ למקומו, כגון שחיטה במקדש ומחשבה לאכול בחוץ, הרי זו פסולה ואין בה כרת. (Rambam, Hilchot Ma'aseh HaKorbanot 17:2)

  2. Hukrav K'Mitzvato (הוקרב כמצוותו): This critical condition from our Mishnah is also codified. Piggul only applies if the haktarah (burning of the kometz or eimurim) was performed "in accordance with its mitzva." This means that if any of the preceding avodot (e.g., kemitzah, netinah, holachah, haktarah itself) were performed with machshevet makom, the offering is immediately pasul and piggul cannot attach, even if machshevet zeman was present at a later avodah.

    ובלבד שהיה ההיתר הוקרב כמצוותו, כלומר שהיו ארבע עבודות כולן ראויות, ושחיטתן וקבלתן והולכתן וזריקת דמן היתה לשמן ובזמנן ובמקומו. (Rambam, Hilchot Pesulei HaMukdashin 18:13, referring to animal offerings; the principle applies to mincha as well with its relevant avodot).

  3. Chesaron (חסרון): The Gemara's discussion about cheseron (lacking measure) and its impact on piggul and meilah leads to the conclusion that an offering with an inherent defect cannot achieve piggul status, nor can meilah be removed from it through avodot. This is a crucial meta-psak heuristic: inherent physical disqualifications (פסול מגויה) are more fundamental than external ones (פסול מחמת דבר אחר) and can prevent subsequent avodot from achieving their halachic effect for piggul or meilah removal. The Rambam reflects this in various places, ruling that an offering that is chasar (lacking) is pasul and cannot be brought, and its avodot are ineffective.

  4. Joining Intents: The Mishnah's ruling that "eating and burning do not join together" (אכילה והקטרה אין מצטרפין) is also halacha. However, the Gemara's subsequent discussion clarifies that two half-k'zayitim of the same type of intent (e.g., half k'zayit to eat outside and half k'zayit to eat beyond its time) do join to create the k'zayit for piggul liability, as long as both intents are for items meant for consumption or burning, respectively. This is a subtle point that distinguishes between qualitatively different intents versus quantitatively split intents.

Takeaway

The sugya in Menachot 12a meticulously defines the precise conditions for piggul liability, underscoring that not all improper intents are equal. It powerfully distinguishes between internal and external disqualifications (cheseron vs. yotzei), revealing how the very nature of a pesul dictates the efficacy of subsequent avodot in the sacrificial process.
