Mishnah Keritot 1:2-3

Hook

Ever wonder why the Torah's most severe penalties for unintentional sins, like bringing a sin offering, are only for actions? Mishnah Keritot reveals a profound distinction between deeds and words, even for offenses as grave as blasphemy.

Context

The Mishnah here details the intricate rules of karet (excision) and korbanot (offerings). It assumes a framework where transgressions, depending on intent (intentional, unwitting, uncertain), trigger different liabilities. Crucially, the Rabbinic tradition developed a fundamental legal distinction between mitzvot aseh (positive commandments) and mitzvot lo ta'aseh (negative commandments), and further, between negative commandments that involve an action and those that do not. This distinction grounds the halakha of sin offerings.

Text Snapshot

Mishnah Keritot 1:2 (https://www.sefaria.org/Mishnah_Keritot_1%3A2-3) For any of these prohibitions, one is liable to receive karet for its intentional violation and to bring a sin offering for its unwitting violation. And for their violation in a case where it is unknown to him whether or not he transgressed, he is liable to bring a provisional guilt offering... ...And the Rabbis say: The halakha is the same even with regard to the one who blasphemes, as it is stated with regard to the sin offering: “You shall have one law for him who performs the action unwittingly” (Numbers 15:29), excluding one who blasphemes, as he does not perform an action.

Structure

The Mishnah first lays down a general rule for karet offenses, then immediately introduces exceptions. This highlights how specific nuances in halakha can override broad principles, pushing us to look beyond surface-level categorizations.

Key Term

The phrase "he does not perform an action" (she'eino ma'aseh) is central. It's not merely that blasphemy is speech; it's that halakha defines "action" for sacrificial liability purposes in a very specific, physical way. This impacts what constitutes an "unwitting sin" requiring a korban chatat.

Tension

There's a fascinating tension here: Blasphemy clearly warrants karet (a divine punishment) when intentional, yet for an unwitting blasphemer, the Rabbis exclude the obligation of a sin offering because "he does not perform an action." This suggests that human-mediated atonement via korbanot has a different scope than divine retribution.

Two Angles

Rambam (Commentary on Mishnah Keritot 1:2) clarifies that Pesach and Milah (positive commandments) and the blasphemer are exempt from sin offerings for unwitting violation. He emphasizes that the Torah explicitly links sin offerings to negative commandments that involve an action ("asher lo ta'asena" - which are not to be done). The Rabbis in our Mishnah take this further, specifically highlighting the "no action" aspect for the blasphemer. While karet still applies for intentional blasphemy, the chatat for unwitting sin is reserved for physically performed negative transgressions.

Practice Implication

This Mishnaic principle encourages us to consider the tangible impact of our actions. While words and intentions are profoundly important ethically and spiritually, the legal system of korbanot for unwitting transgression specifically targets physical deeds. It underscores that while sin is sin, the mechanisms of atonement can differ based on the nature of the transgression.

Chevruta Mini

1. If "action" is so critical, how might we define its boundaries in contemporary halakha? Does pressing a button count? What about a silent thought that leads to a consequence?
2. Given that blasphemy still incurs karet for intentional violation, what does the Rabbis' exemption from a chatat for unwitting blasphemy teach us about the limits of human judicial process versus divine judgment?

Takeaway

For korbanot, the Rabbis taught that only a transgression involving a physical action, not mere speech, warrants a sin offering for unwitting violation.
