Mishnah Keritot 1:2-3

Sugya Map

• Issue: The Mishnah enumerates thirty-six karet offenses and establishes the general rule for their atonement: karet for intentional violation (meizid), a sin-offering (chatat) for unwitting violation (shogeg), and a provisional guilt-offering (asham talui) for uncertain violation (lo noda). Crucially, the Mishnah immediately presents exceptions to this general framework.

Mishnah Keritot 1:2-3:

עַל אֵלּוּ חַיָּבִין עַל זְדוֹנָן כָּרֵת, וְעַל שִׁגְגָתָן חַטָּאת, וְעַל לֹא הֻוְדַּע שֶׁלָּהֶן אָשָׁם תָּלוּי. חוּץ מִן הַמְּטַמֵּא מִקְדָּשׁ וְקָדָשָׁיו, מִפְּנֵי שֶׁהוּא בְעוֹלֶה וְיוֹרֵד, דִּבְרֵי רַבִּי מֵאִיר. וַחֲכָמִים אוֹמְרִים, אַף הַמְגַדֵּף, שֶׁנֶּאֱמַר: "תּוֹרָה אַחַת יִהְיֶה לָכֶם לָעֹשֶׂה בִּשְׁגָגָה", יָצָא מְגַדֵּף שֶׁאֵינוֹ עוֹשֶׂה מַעֲשֶׂה.

Dikduk/Leshon Nuance:

• "על אלו": Refers to the thirty-six karet offenses enumerated in Keritot 1:1. The Mishnah here establishes a klal (general rule) for all of them.
• "זדונן כרת, ועל שגגתן חטאת, ועל לא הודע שלהן אשם תלוי": This tripartite structure is fundamental to the system of korbanot.
• "חוץ מן המטמא מקדש וקדשיו": The first stated exception. The reason given is "מפני שהוא בעולה ויורד" (because it is a sliding-scale offering), a specific type of korban mentioned in Vayikra 5:1-13. The nuance here is that Asham Talui is for uncertainty of sin, while Korban Oleh V'yored can be for a definite sin (if the sinner is poor), but its type also changes based on financial status.
• "דברי רבי מאיר": This indicates a machloket (dispute) immediately after the first exception.
• "וחכמים אומרים, אף המגדף": The Rabbis add Megadef (blasphemer) as another exception.
• "שאינו עושה מעשה": This is the crucial reason provided by the Rabbis for Megadef's exemption, hinting at the principle of lav she'ein bo ma'aseh (a negative commandment that does not involve a physical act). This distinction between speech/thought and action becomes central. The verse "תורה אחת יהיה לכם לעושה בשגגה" (Bamidbar 15:29) is interpreted restrictively, applying only to those who perform an action.

Readings

Rambam on Mishnah Keritot 1:2:1

Rambam, in his commentary to the Mishnah, meticulously defines the terms and clarifies the scope of the exceptions.

• Defining Shogeg and Lo Noda: Rambam first explicates the distinction between these two states of unwitting transgression. Shogeg (שגגה) is when one certainly committed the act, but did so mistakenly (e.g., ate what he thought was permitted fat, only to discover it was cheilev). For this, a chatat is due. Lo Noda (לא הודע) is when one is uncertain whether they committed the act at all (e.g., ate one of two pieces, one permitted, one forbidden, and is unsure which). For this, an Asham Talui is due.¹
• Exceptions to Chatat and Asham Talui: Rambam identifies three categories of karet offenses that do not incur a chatat for shogeg or an asham talui for lo noda:
  1. Pesach* and *Milah: These are mitzvot asseh (positive commandments). The Torah's requirement for a chatat for shogeg is stated in the context of "אשר לא תעשינה" (which shall not be done – Vayikra 4:27), implying only mitzvot lo ta'aseh (negative commandments). Since Pesach and Milah are positive commands, even though their intentional neglect carries karet, their unwitting neglect does not trigger a chatat.²
  2. Megadef (Blasphemer): Rambam aligns with the Rabbis' view, stating that Megadef is exempt from a chatat for shogeg because "אינו עושה מעשה" (he does not perform an action). The verse "לעושה בשגגה" (Bamidbar 15:29) explicitly limits chatat to transgressions involving an action.³
  3. Metameh Mikdash v'Kodashav (Defiling the Temple or its Sacrifices): This case is unique. While it carries karet for intentional violation, for unwitting transgression, one brings a Korban Oleh V'yored (a sliding-scale offering), not a chatat kevua (fixed sin-offering). Rambam clarifies that an Asham Talui is only brought for a sin that would ordinarily incur a chatat kevua. Since Metameh Mikdash involves a Korban Oleh V'yored (whose nature changes with the offender's financial status), it is exempt from Asham Talui.⁴ His chiddush is highlighting the chatat kevua requirement for asham talui.

Mishnat Eretz Yisrael (ME"Y)

Mishnat Eretz Yisrael provides a deeper, contextual analysis, often exploring the historical and conceptual underpinnings of the Mishnah's statements.

• The Nature of Karet and Chazal's Interpretation: ME"Y points out that the Mishnah's statement that karet is only for meizid is a Chazal interpretation. While some verses mention karet alongside yad rama (Bamidbar 15:30), which Chazal interpreted as meizid, this isn't universally explicit in the Torah for all karet offenses. This shows Chazal's active role in systematizing biblical law.⁵
• The Lo Ta'aseh / Asseh Distinction as a Chazal Innovation: ME"Y posits that the distinction between mitzvot asseh and lo ta'aseh is a conceptual-legal framework developed by Chazal, not explicitly found in earlier sources like Josephus, Philo, or Qumran literature. This formalistic interpretation of "אשר לא תעשינה" (Vayikra 4:27) to exclude mitzvot asseh from chatat liability is a cornerstone of this system.⁶ This is a significant chiddush, framing the Mishnah's legal structure as a sophisticated post-biblical development.
• Rationale for Metameh Mikdash Exception: Beyond the technical reason of Korban Oleh V'yored, ME"Y suggests a sociological motivation: to encourage pilgrimage to the Temple. The potential fear of defiling the Temple inadvertently (and thus incurring a costly offering) might have deterred people. By lowering the hierarchical severity of the atonement (from chatat kevua to oleh v'yored for definite transgression, and exemption from asham talui for uncertainty), Chazal aimed to ease participation in Temple life, reflecting a policy of "הקלו בטומאת המקדש... רצו לעודד כניסה למקדש".⁷ This offers a chiddush of policy-driven halakha.
• The Principle of Lav She'ein Bo Ma'aseh: ME"Y extensively analyzes the Rabbis' reason for exempting Megadef – "שאינו עושה מעשה". This principle, lav she'ein bo ma'aseh (a negative commandment not involving a physical act), is not merely a technicality. ME"Y traces its evolution and notes its profound implications: generally, such transgressions are exempt from malkot (lashes), korbanot, and potentially even karet. While there are historical debates and exceptions (e.g., memir, swearing falsely), the core idea is that "מחשבות ואמונות, ואולי אף דברי כפירה, אינם גוררים ענישה".⁸ This is a "מהפכנית" (revolutionary) distinction, limiting human judicial power to tangible actions, rather than thoughts or speech, even in cases of heresy, which ME"Y contrasts with other religions.⁹ This offers a meta-halachic chiddush on the philosophical underpinnings of Jewish law regarding punitive measures.

Friction

The Grand Kushya: Exceptions to the Rule

The Mishnah lays down a clear, comprehensive rule: karet for meizid, chatat for shogeg, asham talui for lo noda. Yet, it immediately carves out exceptions. The most profound kushya arises from the very basis of these exceptions, particularly Megadef and Metameh Mikdash, and the implied exceptions of Pesach and Milah. How can a transgression be severe enough to warrant karet (the ultimate heavenly punishment), yet simultaneously be exempt from the standard atonement mechanisms for unwitting or uncertain violation? This seems to undermine the very systematic approach the Mishnah is trying to establish.

Specifically:

1. Why are Pesach and Milah different? They are listed among the 36 karet offenses, yet are understood not to bring a chatat for shogeg.
2. Why is Megadef explicitly excluded by the Rabbis due to "שאינו עושה מעשה"? Isn't speech a form of action, especially when it involves such a grave sin?
3. Why is Metameh Mikdash v'Kodashav singled out by R' Meir for its Korban Oleh V'yored status, leading to exemption from Asham Talui? What's so special about this karet offense?

Rashash, in his note on Keritot 1:2:1, highlights a subtle point regarding the Metameh Mikdash exclusion. He questions a Tosefot Yom Tov interpretation concerning bamot (private altars) and their permissibility, stating "לא הבנתי דאימתי נאסרו הבמות בשילה ובב"ע" (I do not understand when the bamot were forbidden, in Shiloh or during the Second Temple era).¹⁰ While his comment is on a specific detail within Tosefot Yom Tov's explanation of shogeg, it underscores the need for precise historical and halachic context when dealing with seemingly straightforward statements about Temple-related laws. He further notes on the Rabbis' statement "אדר"מ מהדר דאמר חוץ ממטמא מקדש וקדשיו כו'. ואינו כלום דחוץ ממטמא כו' אינו מפיק אלא מא"ת כדמפרש הש"ס לעיל. ומגדף לדברי חכמים פטור אף בודאי חטא" (The Rabbis are responding to R' Meir who said 'except for one who defiles the Temple...'. This is incorrect, as 'except for one who defiles...' only exempts from Asham Talui as explained earlier by the Gemara. But the Megadef, according to the Rabbis, is exempt even from a definite sin-offering).¹¹ This suggests that the scope of exemption for Metameh Mikdash (only from Asham Talui) is different from Megadef (from chatat entirely).

The Best Terutz: Systemic Coherence through Categorization

The apparent friction dissolves when we appreciate the distinct halachic categories at play, as elucidated by Rishonim and Acharonim.

1. Pesach* and Milah as *Mitzvot Asseh: As Rambam explains, the Torah's requirement for a chatat for unwitting transgressions is explicitly linked to "אשר לא תעשינה" (Vayikra 4:27). This phrase refers to negative commandments. Pesach and Milah, though critical and bearing karet for intentional non-observance, are fundamentally positive commandments (to offer the Paschal lamb, to circumcise). Thus, their omission, even unwittingly, does not fall under the chatat rubric defined by the Torah for lo ta'aseh. This is not an arbitrary exception but a direct consequence of a strict, formalistic reading of the source verses, a chiddush of Chazal's legal system as ME"Y highlights.

2. Megadef* and *Lav She'ein Bo Ma'aseh: The Rabbis' reasoning "שאינו עושה מעשה" for Megadef is a cornerstone of the halachic penal system. This principle, elaborated by ME"Y, distinguishes between transgressions involving a physical act and those involving speech or thought. While blasphemy is a grave sin, it does not involve a tangible, physical ma'aseh in the same way eating cheilev or performing forbidden labor does. The verse "לעושה בשגגה" (Bamidbar 15:29) is interpreted to mean "one who performs an action unwittingly". Since speech, in this context, is not considered a ma'aseh sufficient to trigger a chatat, the Megadef is exempt. This reflects a profound theological and legal choice within Judaism, limiting human judicial and sacrificial accountability to demonstrable actions, not intentions or mere utterances in certain contexts.

3. Metameh Mikdash* and *Korban Oleh V'yored: R' Meir's reasoning for Metameh Mikdash is "מפני שהוא בעולה ויורד". This refers to the unique Korban Oleh V'yored (Vayikra 5:1-13), a sacrifice whose type (animal, bird, or flour) varies based on the offender's financial status. Rambam clarifies that Asham Talui is exclusively brought for sins that, if definite and unwitting, would require a chatat kevua (a fixed, non-variable sin-offering). Since Metameh Mikdash requires an oleh v'yored – a variable offering – it falls outside the Asham Talui framework. ME"Y adds a socio-religious dimension: this leniency may have been a policy decision to encourage pilgrimage, mitigating the fear of inadvertent Temple defilement. This transforms a technicality into a pragmatic, community-oriented halachic ruling. Rashash further clarifies that this exemption only pertains to Asham Talui, not necessarily from a chatat for definite shogeg.

Thus, the Mishnah is not presenting arbitrary exceptions but rather demonstrating a highly sophisticated, layered halachic system where different categories of transgressions (positive/negative, action/speech, fixed/variable offering) lead to distinct legal outcomes, even within the overarching framework of karet.

Intertext

Bamidbar 15:29-30 — The Source of the Chatat Distinction

The Mishnah's discussion on Megadef directly references Bamidbar 15:29: "תּוֹרָה אַחַת יִהְיֶה לָכֶם לָעֹשֶׂה בִּשְׁגָגָה מִבְּנֵי יִשְׂרָאֵל וּמִן הַגֵּר הַגָּר בְּתוֹכָם." The Rabbis' interpretation, "יָצָא מְגַדֵּף שֶׁאֵינוֹ עוֹשֶׂה מַעֲשֶׂה," hinges on the word "לָעֹשֶׂה" (one who performs). This restrictive reading establishes the principle of lav she'ein bo ma'aseh, which differentiates sins of omission or speech from those involving a physical act. Immediately following, Bamidbar 15:30 addresses the intentional transgressor: "וְהַנֶּפֶשׁ אֲשֶׁר תַּעֲשֶׂה בְּיָד רָמָה מִן הָאֶזְרָח וּמִן הַגֵּר אֶת יְהוָה הוּא מְגַדֵּף וְנִכְרְתָה הַנֶּפֶשׁ הַהִוא מִקֶּרֶב עַמָּהּ." This verse itself mentions Megadef in the context of karet for intentional sin, but the Rabbis' exegesis separates the karet punishment (which applies to Megadef) from the chatat requirement (which does not, due to the lack of ma'aseh). This demonstrates the precise textual analysis required to construct the halachic framework.¹²

Vayikra 5:1-13 — The Korban Oleh V'yored

The exception of Metameh Mikdash v'Kodashav "מפני שהוא בעולה ויורד" directly points to the laws of Korban Oleh V'yored in Vayikra 5:1-13. This chapter details various scenarios requiring a korban chatat, including one who touches an impure thing and does not know it, or swears falsely. Crucially, it outlines a sliding scale: if one is poor, they can bring two birds or even a tenth of an ephah of fine flour instead of an animal. The relevant verse for Asham Talui is Vayikra 5:17-19, which discusses the asham for an uncertain sin. The Mishnah's statement, and Rambam's explanation, highlight that the oleh v'yored characteristic of the Metameh Mikdash chatat (when definite) makes it qualitatively different from other chatatot that require a fixed animal offering, thus excluding it from the Asham Talui category. This distinction showcases the nuanced classification of korbanot based on their nature and purpose, not just the severity of the sin.¹³

Psak/Practice

The halachot discussed in Mishnah Keritot 1:2-3, pertaining to karet, chatat, and asham talui, are intrinsically linked to the Temple service and are not practically observed in a post-Temple era. With the destruction of the Beit Hamikdash, the bringing of korbanot ceased. Thus, the direct application of these laws concerning chatat and asham talui for unwitting or uncertain karet transgressions is currently in abeyance.

However, the meta-halachic principles articulated by the Mishnah and its commentators remain profoundly relevant.

1. Categorization of Mitzvot: The distinction between mitzvot asseh and lo ta'aseh is fundamental to all areas of halacha, influencing everything from malkot liability to the nature of tshuvah.
2. The Principle of Lav She'ein Bo Ma'aseh: This principle, that negative commandments not involving a physical act are generally exempt from certain punishments (like malkot), is still a live wire in halachic discourse. It shapes our understanding of accountability for speech acts (e.g., lashon hara, false oaths) versus physical transgressions. While karet is a heavenly punishment, the legal reasoning for its non-liability to a chatat for shogeg due to "אין בו מעשה" informs other areas of Jewish law concerning human-administered penalties.
3. Encouraging Observance: ME"Y's insight into the policy rationale behind the Metameh Mikdash exception – encouraging pilgrimage by reducing the punitive burden – provides a heuristic for understanding how halacha can adapt to foster greater religious engagement, balancing strict justice with communal needs. This meta-psak approach can be seen in various takanot (rabbinic enactments) throughout Jewish history.

Takeaway

Mishnah Keritot 1:2-3, by delineating the general rules and precise exceptions for karet atonement, reveals a deeply sophisticated halachic system that categorizes transgressions not just by severity, but by type of commandment, nature of action, and even socio-religious policy. This framework, though currently theoretical in practice, continues to inform fundamental principles of Jewish legal thought regarding accountability and atonement.
