Text Snapshot

“I am a nazir for 100 days,” if he became impure on day 100 he invalidated everything but Rebbi Eliezer said, he invalidated only 30.49And the implicit vow of a nazir run for 30 days. If he became impure on day 101, he invalidated 30; Rebbi Eliezer said, he invalidated only seven.41Since he could have brought the sacrifices on the 30th day, he has to wait 7 days to cleanse himself from the impurity of the dead, shave, bring the sacrifices prescribed for the impure nazir, wait another 7 days to have some hair to shave, and then brings his 3 sacrifices and shaves in purity.

Jerusalem Talmud Nazir 3:4:1-2 (Mishnah)

The phrase "סתר את הכל" (soter et hakol - invalidated everything) indicates a complete nullification of the preceding days, requiring a full restart. Conversely, "סתם נזירות שלשים יום" (stam nezirut shloshim yom - the default nezirut is thirty days) points to the minimum period, which becomes the measure of invalidated days in certain scenarios. The distinction between "day 100" (day of completion) and "day 101" (day after completion) is critical, highlighting the differing views on when the nezir is considered to have potentially concluded his vow.

“If somebody made a vow of nazir while he was in a cemetery... even if he stayed there for thirty days, they are not counted and he does not bring a sacrifice for impurity... If he left and re-entered, they are counted and he has to bring a sacrifice for impurity.”

Jerusalem Talmud Nazir 3:5:1-2 (Mishnah)

The contrast between days "not counted" and days that "are counted" directly impacts the nezirut period. The phrase "אינו מביא קרבן טומאה" (eino meivi korban tum'ah - does not bring a sacrifice for impurity) is significant, implying that the impurity contracted in the cemetery under these circumstances doesn't necessitate the special sacrifices for an impure nazir, suggesting the vow itself is in abeyance or invalid.

Readings

Rebbi Eliezer's Rationale: The "Day of Fulfillment" Decree

The Gemara grapples with Rebbi Eliezer's position regarding impurity on the day of melo'at (fulfillment). Rebbi Ze'ira, citing Rebbi Shimon ben Laqish, explains Rebbi Eliezer's leniency: "This is the teaching for the nazir on the day of his fulfilling; if he becomes impure on the day of his fulfilling, one gives him the teaching for the nazir." The interpretation hinges on Numbers 6:13: "וזאת תורת הנזיר ביום מלאת את ימי נזרו" (v'zot torat hanazir b'yom milo'et et y'mei naziro - "And this is the law of the Nazir on the day of the fulfillment of the days of his Nazirship"). Rebbi Eliezer infers from this verse that the laws specific to the day of fulfillment are applied when impurity occurs on that day. As the stam nezirut (default nezirut) is 30 days, impurity on the day of fulfillment for a longer vow means only these 30 days are invalidated, representing the standard nezirut period.

  • Chiddush: Rebbi Eliezer connects the verse about the day of fulfillment directly to the consequence of impurity on that very day, limiting the invalidation to the standard 30-day nezirut period, rather than the entire vow.

Rebbi Yochanan and Rebbi Shimon ben Laqish on Vowing in a Cemetery

The discussion shifts to vows made in a cemetery. Rebbi Yochanan posits that one warns the individual about wine and shaving immediately upon taking the vow, even while still in the cemetery and impure. His reasoning, as clarified by the rabbis of Caesarea, is that the vow is valid from its utterance, and the prohibitions of wine and shaving are applicable even if the nazir cannot currently observe them due to impurity. However, the Gemara notes a potential contradiction with another instance where Rebbi Yochanan requires warning about impurity itself.

Rebbi Shimon ben Laqish, conversely, argues that since the individual cannot be warned about impurity (because he is already impure), he is not warned about wine and shaving either. This implies his vow is suspended until he undergoes purification.

  • Chiddush: Rebbi Yochanan focuses on the immediate activation of all nezirut prohibitions, even if currently impossible to observe. Rebbi Shimon ben Laqish prioritizes the practical ability to observe a prohibition as a prerequisite for warning and punishment.

Rebbi Tarfon and Rebbi Akiva on Re-entering the Cemetery

When a nazir who vowed in a cemetery leaves and then re-enters, Rebbi Tarfon frees him from prosecution, asking, "What did this one add to his desecration?" since he was already impure. Rebbi Akiva, however, declares him guilty, explaining that leaving and re-entering signifies a change in the type of impurity. While in the cemetery, he might have been subject to the "impurity of seven days" (from contact with a corpse or a tent of impurity). Upon leaving and re-entering, he could be subject to the "impurity of evening" (secondary impurity), or even again the "impurity of seven days" if he re-engages with impurity. This change in impurity status, according to Rebbi Akiva, constitutes a new offense.

  • Chiddush: Rebbi Tarfon views impurity as a continuous state, rendering repeated exposure less culpable. Rebbi Akiva introduces a nuanced understanding of impurity, where the form and source of impurity can change, creating distinct offenses.

Friction

The Core Dispute: Decree or Direct Law?

The most significant point of friction lies in the interpretation of impurity on the day of melo'at. The standard interpretation of the Mishnah and the Gemara's initial explanation of Rebbi Eliezer's position centers on the verse "וזאת תורת הנזיר ביום מלאת" (Numbers 6:13). Rebbi Eliezer, deriving his ruling from this verse, limits the invalidation to the standard 30-day nezirut. The Rabbis, in contrast, invalidate "everything" (soter hakol).

The Penei Moshe explains the Rabbis' position: "Rabbonan [the Rabbis] said, 'They have decreed the day after the hundredth day, which is the day of shaving, as if it were the day of the hundredth, and they invalidate everything.'"¹ This points to a Rabbinic decree (gzeirah) to prevent transgressing on the day of completion. The Korban Ha'edah echoes this, stating, "The Rabbis, according to their reasoning, say that if he becomes impure on the day of fulfillment, it is as if he became impure within the period of fulfillment, and he invalidates everything."²

The friction arises because Rebbi Eliezer seems to be deriving his leniency directly from a verse, while the Rabbis are imposing a decree. However, the Korban Ha'edah's explanation of Rebbi Eliezer's view on day 101, where he invalidates only seven days, further complicates this: "To his reasoning he follows, as he holds in the previous Mishnah [3:3] regarding one who says 'I am a Nazir without specifying a number of days,' that even if he becomes impure on the thirtieth day, he invalidates only seven days."³ This suggests Rebbi Eliezer's leniency extends even beyond the specific verse, to a general principle of minimal invalidation for impurity on the very last day of a vow, derived from the concept of minimal impurity consequence even in standard nezirut.

The critical question is: Why do the Rabbis impose a decree (gzeirah) when Rebbi Eliezer appears to have a direct scriptural basis for his leniency? Or, conversely, is Rebbi Eliezer's interpretation of the verse too narrow, and the Rabbis' decree a necessary safeguard?

Best Terutz: The Penei Moshe's explanation that the Rabbis decreed the day after fulfillment as if it were the day of fulfillment suggests that the verse in Numbers 6:13 might be understood by Rebbi Eliezer as applicable to impurity on that day. The Rabbis, however, might argue that the verse is primarily about the sacrifices and laws after completion, and that impurity on that specific day should still be treated as falling within the nezirut period, thus necessitating the gzeirah of invalidating all days to uphold the sanctity of the melo'at. The Penei Moshe also mentions that for impurity on day 101, the Rabbis decreed 30 days, not the full amount, implying the decree is calibrated, not absolute. This suggests a tension between preserving the sanctity of the final day and not over-punishing the nazir. Rebbi Eliezer's view, perhaps rooted in hakol kol, avoids a gzeirah altogether, relying on the verse's explicit mention.

The Cemetery Vow: Suspension or Abeyance?

A secondary friction point emerges in the debate between Rebbi Yochanan and Rebbi Shimon ben Laqish regarding vows made in a cemetery. Rebbi Yochanan states, "one warns him about wine and shaving." The rabbis of Caesarea clarify, "It is understood: because from the start one also warns him about impurity."⁴ This implies Rebbi Yochanan believes the vow is valid ab initio, and all prohibitions, including impurity, apply, even if the nazir is currently unable to fulfill them.

Rebbi Shimon ben Laqish, however, states, "since one cannot warn him because of impurity, one does not warn him about wine and shaving."⁵ This suggests that the inability to warn about a specific prohibition (impurity) renders the entire vow suspended.

The nafka mina here is whether the vow is immediately binding in all its aspects, requiring warnings even for currently impossible observances (Rebbi Yochanan), or whether it's contingent on the ability to observe the primary prohibitions. The Penei Moshe notes that Rebbi Yochanan's position seems inverted compared to another context, suggesting this is a complex application of principles.

Best Terutz: Rebbi Yochanan's approach emphasizes the intention and halachic status of the nezirut vow, which is established the moment it is uttered. The cemetery's impurity is a temporary impediment, not a negation of the vow itself. Therefore, the nazir is warned of all his obligations. Rebbi Shimon ben Laqish, conversely, prioritizes the practical enforceability of the vow. If the individual is already impure, the prohibition against becoming impure is moot, and thus the entire framework of warnings and potential punishment is suspended until he attains a state where he can observe the rules. This aligns with the principle that halachah often considers practical realities.

Mishneh Torah: Hilchot Nezirut 6:4

Maimonides, in his Mishneh Torah, codifies the ruling regarding impurity on the day after the completion of the vow: "If he contracted impurity on the day after he completed [his nazirite vow], i.e., the day on which he would have brought the sacrifices... he invalidates only 30 days."⁶ This directly reflects the majority opinion presented in the sugya, which aligns with the stam nezirut of 30 days. Maimonides further adds, "The commentaries discuss whether the invalidation of the 30 days is a Scriptural requirement or a Rabbinic decree."⁷ This mirrors the tension identified in the sugya between Rebbi Eliezer's scriptural interpretation and the Rabbis' decree.

Numbers 6:12: "The earlier days fall away"

The verse "הַיָּמִים הָרִאשֹׁנִים יִפְּלוּ" (hayamim harishonim yippelu - "the earlier days shall fall away") is central to the discussion. The Gemara notes in the Mishnah's context (3:5) that Rebbi Eliezer interprets this to mean that a sacrifice is only due if there are at least two days preceding the impurity.⁸ This implies a minimum period is required for the concept of "falling away" to apply. This principle is crucial when considering the calculation of days and the requirement for sacrifices after impurity. The sugya implicitly debates whether this verse applies to impurity on the day of completion itself, or only to impurity within the nezirut period.

Psak/Practice

The prevailing practice, as reflected in Maimonides and the general understanding of the sugya, is that impurity on the day after the completion of a nezirut vow invalidates 30 days. This is a Rabbinic decree (gzeirah) to safeguard the sanctity of the completion day. Rebbi Eliezer's view, while noted, is not the accepted halacha in this specific instance.

Regarding vows made in a cemetery, the halacha generally follows Rebbi Yochanan's approach: the vow is valid from its utterance, and the nazir is warned of all prohibitions, even if currently unable to fulfill them due to impurity. However, the specific application and implications of warnings, particularly concerning punishment, can be complex and depend on further context and interpretation.

The principle of hakol kol (part of a day is like the whole day) is implicitly at play, affecting how partial days are counted, especially in cases of nezirut for oneself and a son.

Takeaway

The sugya demonstrates how Rabbinic decrees (gzeirot) can extend or modify scriptural law to ensure observance and uphold sanctity, even when a direct scriptural interpretation might lead to a more lenient outcome. The precise timing of impurity relative to the completion of a vow, and the context of its occurrence (e.g., in a cemetery), significantly impact its halachic ramifications.
