Mishnah Keritot 4:3-5:1

Sugya Map

• Issue: Delineating liability for asham talui and chatat in cases of safek (uncertainty), particularly regarding the categories of transgression (shem echad vs. shnei shemot) and the definition of metasek (unintentional/accidental action).
• Nafka Mina: When does an unwitting transgression necessitate a definite chatat, a provisional asham talui, or lead to complete exemption?
• Primary Sources: Mishnah Keritot 4:3-5:1; Sifra, Vayikra 4:23 ("אשר חטא בה").

Text Snapshot

"רבי שמעון ורבי שמעון שזורי אומרים: לא נחלקו על דבר שהוא משם אחד, שהוא חייב. על מה נחלקו? על דבר שהוא משום שני שמות, שרבי אליעזר מחייב חטאת ורבי יהושע פוטר." (Keritot 4:3)

Dikduk/Leshon Nuance

The phrase "משם אחד" (from one category/name) versus "משום שני שמות" (due to two categories/names) is critical. Shem here refers to the classification of the transgression or the object of transgression, influencing whether the act is deemed a single, defined sin or an ambiguous one.

Readings

Rambam (Mishnah Keritot 4:3:1)

Rambam clarifies R' Yehuda's "תמה אני" (I wonder) concerning R' Yehoshua's exemption. He explains that R' Yehoshua's exemption extends even to cases where one intended to perform an issur, but carried out a different issur (e.g., intended to pick figs, picked grapes). This is considered metasek regarding the actual sin, thus exempting per "אשר חטא בה."

Rashash (Mishnah Keritot 4:3:1-3)

The Rashash addresses the apparent contradiction in Rashi regarding metasek—sometimes exempt, sometimes liable (e.g., arayot/chalavim). He suggests Rashi aligns with Abaye and Rava who distinguish: metasek is exempt only if one intended a permitted act (e.g., thought it was detached), not if he intended issur but performed a different kind of issur (i.e., shnei shemot). R' Yehoshua's exemption for shnei shemot is rooted in the lack of specific intent for the actual sin.

Friction

The "Metasek" Conundrum

• Kushya: If R' Yehoshua exempts for shnei shemot (e.g., intended figs, picked grapes), how does this reconcile with the Torah's "אשר חטא בה" (Leviticus 4:23), which the Mishnah itself derives to "פרט למתעסק" (to exclude one who acts unawares)? If one intended any prohibited labor, why should the specific type of labor matter for exemption?
• Terutz: Rambam (Mishnah Keritot 4:3:1) explains that for R' Yehoshua, "בה" demands precise intent. If one intended to pick figs (an issur) but picked grapes (also an issur), he is metasek regarding the actual act of picking grapes because his intent was not for that specific fruit. Thus, even though both are issur, the lack of specific intent for the performed transgression is akin to metasek. The Rashash (Mishnah Keritot 4:3:2) further refines that R' Yehoshua limits liability in shnei shemot because the issur itself is not precisely defined by the initial intent.

Intertext

• Sifra, Vayikra 4:23: The exegesis "אשר חטא בה" — "פרט למתעסק" (excluding one who acts unawares) forms the textual bedrock for distinguishing between a liable unintentional sin and an exempt accidental act.
• Shabbat 72b (via melakhet makhshevet): The principle of melakhet makhshevet (intentional creative labor) as the basis for Shabbat liability parallels the concept of specific intent required for chatat, further clarifying the metasek exemption.

Psak/Practice

The halakha generally follows R' Yehoshua's principle that for a chatat one must have intended the specific issur that was transgressed. However, a critical distinction applies: metasek in arayot (forbidden sexual relations) or chalavim (forbidden fats) is chayav (liable) even if the intent was not perfectly aligned, because one derives hana'ah (benefit) from the act, and hana'ah is considered a form of intent in these contexts (Shabbat 19a, Rambam, Hil. Shegagot 1:8).

Takeaway

The intricate debate surrounding shem echad vs. shnei shemot and the precise definition of metasek underscores the paramount role of specific intent in determining chatat liability, modulated by the nature of the transgression itself.
