Jerusalem Talmud Nazir 2:4:1-5:3

Sugya Map

The Yerushalmi in Nazir 2:4-5 presents a rich tapestry of halakhic inquiry, weaving together diverse principles of nedarim and nezirut. The sugya can be broadly divided into two primary axes: the validity of conditional nezirut and the intricacies of shared nezirut obligations.

The Validity of Conditional Nezirut (Mishnah 2:4:1)

This section delves into the foundational question of when a nazir vow, made with a qualifying condition or under a misapprehension, takes effect.

• Issue 1: Condition Contradicting Torah Law. A person declares, "I am a nazir on condition that I may drink wine or become impure for the dead."
  • Nafka Mina: Is the nezirut valid, and the condition void? Or is the entire vow invalidated by the impossible condition?
  • Primary Sources: Yerushalmi Nazir 2:4:1, Yerushalmi Ketubot 9:1:1 (Note 51), Numbers 6:2.
• Issue 2: Ignorance of Neziritic Prohibitions. A person vows nezirut but claims ignorance of specific prohibitions (e.g., wine).
  • Nafka Mina: Is the vow valid, as one accepts the general nezirut framework? Or is it invalid due to incomplete kavana?
  • Primary Sources: Yerushalmi Nazir 2:4:1, Numbers 6:2.
• Issue 3: Mistaken Assumption of Halakhic Dispensation (Nidrei Shogegot). A person vows nezirut knowing the prohibitions, but believing the Sages would grant an exception due to a vital need (e.g., medical need for wine, undertaker profession).
  • Nafka Mina: Is this a valid nezirut requiring annulment, or is it automatically voided by the fundamental error? Does R. Shimon distinguish between types of error?
  • Primary Sources: Yerushalmi Nazir 2:4:1, Mishnah Menachot 12:3, Bavli Nazir 11b, Tosefta Nazir 2:3, Nedarim Chapter 9.

The Dynamics of Shared Neziritic Obligations (Mishnah 2:5:1)

This section explores linguistic and chronological complexities surrounding vows to pay for a nazir's sacrifices.

• Issue 1: Scope of "I Also" (אף אני). One person vows, "I shall be a nazir and obligate myself to shave a nazir." Another responds, "I also."
  • Nafka Mina: Does "I also" encompass both nezirut and the shaving obligation, or only the nezirut itself? This impacts the number of sacrifices each must bring.
  • Primary Sources: Yerushalmi Nazir 2:5:1, Bavli Nazir 11b.
• Issue 2: Chronology of Self-Fulfillment. Can one fulfill a vow to shave a nazir by shaving oneself, if the vow to shave preceded one's own nezirut?
  • Nafka Mina: Does the order of vows matter? Can a person retroactively apply a general obligation to a specific, later-acquired obligation?
  • Primary Sources: Yerushalmi Nazir 2:5:1.
• Issue 3: Obligation for Future Nezirim / Davar Shelo Ba Le'olam. Can one obligate oneself for the sacrifices of a nazir who is not yet a nazir? Can one make a condition on things not yet in existence?
  • Nafka Mina: What are the limits of arvut (guarantee) and kinyanim (acquisitions) for future, non-existent entities?
  • Primary Sources: Yerushalmi Nazir 2:5:3, Yerushalmi Ketubot 9:1:4.

Text Snapshot

The sugya unfolds across two Mishnayot and their accompanying Halakhot (Gemara).

Mishnah Nazir 2:4:1

"הריני נזיר על מנת שאשתה יין או שאטמא למתים, הרי זה נזיר ואסור בכולן."

"I am a nazir on condition that I may drink wine or become impure for the dead," he is a nazir and forbidden everything.

The apodictic "הרי זה נזיר ואסור בכולן" immediately establishes the halakha for the first case: the condition is void, the nezirut is firm. This echoes the principle of "כל המתנה על מה שכתוב בתורה תנאו בטל" (Yerushalmi Ketubot 9:1:1, Note 51).

"אמרתי יודע אני שיש נזירים, אבל לא הייתי יודע שהיין אסור לנזיר — הרי זה אסור, ורבי שמעון מתיר."

"I knew that there are nezirim but I did not know that wine is forbidden to the nazir"; wine is forbidden to him, but Rebbi Simeon permits.

Here, the Mishnah introduces a machloket. The Rabanan (implied by "הרי זה אסור") hold the vow is valid despite ignorance of a specific prohibition. R. Shimon, however, permits, suggesting a more stringent requirement for kavana or knowledge of all aspects of the vow. The phrase "היין אסור לנזיר" is specific, yet the ruling "אסור" (forbidden) implies all prohibitions apply.

"אמרתי יודע אני שהיין אסור לנזיר, אבל סבור הייתי שהחכמים מתירין לי מפני שאיני יכול לחיות בלא יין, או מפני שאני קובר את המתים — הרי זה מותר, ורבי שמעון אוסר."

"I knew that wine was forbidden to the nazir but I thought that the Sages would permit me because I cannot live without wine, or because I am an undertaker;" he is permitted but Rebbi Simeon forbids.

This third clause presents a fascinating reversal. Rabanan are lenient ("הרי זה מותר"), while R. Shimon is stringent ("ורבי שמעון אוסר"). This case involves a mistaken assumption about halakhic dispensation, rather than ignorance of the halakha itself. The dikduk of "סבור הייתי" (I thought) is key, denoting a shegaga (error) in judgment or expectation.

Halakha Nazir 2:4:2

"המשנה כרבי מאיר, שרבי מאיר אומר: צריכין לעשות תנאי כפול."

The Mishnah follows Rebbi Meïr, since Rebbi Meïr says, one has to double one’s stipulation.

The Gemara immediately seeks to identify the Tanna of the first clause, connecting it to R. Meir's requirement for a tnai kaful (double stipulation, as found in Kiddushin 3:3). This implies that since the nazir did not state, "If I cannot drink wine, then I am not a nazir," the condition is invalid, and the nezirut stands.

Halakha Nazir 2:4:3-6

This section unpacks R. Shimon's positions and the apparent contradictions. "המשנה כרבי מאיר או רבי יהודה בן תימא."

The Mishnah follows Rebbi Meïr or Rebbi Jehudah ben Tema.

The Gemara offers an alternative attribution for the first clause, R. Yehudah ben Tema, who holds that an impossible condition is nullified, leaving the primary act intact (Gittin 84a). This provides another lens through which to understand the voiding of the condition.

The Gemara then directly addresses the machloket with R. Shimon, particularly the reversal in the third clause. R. Yehoshua ben Levi suggests a nafka mina of shaving, but R. Yirmeyah challenges this. The resolution hinges on the concept of "פתח לנדר" (an opening for the annulment of a vow). For Rabanan, the vital need in the third case automatically constitutes a petach. For R. Shimon, however, such a petach is not automatic and requires a chakham for annulment, hence his stringency. The phrases "מפני שהוא קושר את נדרו בחייו" (because he connects his vow with his life) and "אומנתו לקבור את המתים" (it is his profession to bury the dead) highlight the extremity of the shegaga that Rabanan deem sufficient for petach.

Mishnah Nazir 2:5:1

"הריני נזיר ואני מגלח נזיר, שמע חבירו ואמר אף אני הריני ואני מגלח נזיר. אם היו פקחין מגלחין זה את זה."

"I shall be a nazir and obligate myself to shave a nazir," if another heard him and said: "I also shall be and I obligate myself to shave another nazir," if they are clever, they will shave one another.

This Mishnah introduces the second sugya, focusing on the linguistic interpretation of "אף אני" (I also) and the implications for shared nezirut obligations. The term "מגלח נזיר" refers to the obligation to pay for the sacrifices of a nazir (Jerusalem Talmud Berakhot 7:3, Notes 78–89). The Mishnah's emphasis on "אם היו פקחין" (if they are clever) hints at a specific interpretation of their vows that allows for mutual fulfillment.

Halakha Nazir 2:5:2-3

"האי אף אני מה את מכלל המילתא את, או מכלל פלגא דמילתא את."

This "I also", what do you subsume under it? Does "I also" refer to the entire sentence, or does "I also" only refer to part of the sentence?

The Gemara immediately poses the critical linguistic question. Beit Rebbi rules "אף אני מכלל מילתא," meaning it refers to the entire sentence. R. Yose, however, infers from the Mishnah that "אף אני" might refer only to the nezirut itself, not to specific terms like the number of days or the shaving obligation, unless explicitly stated ("אני כמותו, אני כמותו").

The sugya then delves into the chronology of self-fulfillment: "הריני חייב לגלח חצי נזיר, ואחר כך אמר הריני נזיר, אם גילח את עצמו יצא ידי חובתו." (Nazir 2:5:2). This establishes that if the obligation to shave another precedes one's own nezirut, one can fulfill it by shaving oneself. R. Yose, however, challenges this from the Mishnah's "אבל לא עצמן" (but not themselves) inference, implying that a vow to shave a nazir made after one's own nezirut cannot be applied to oneself.

Finally, the discussion shifts to obligating oneself for davar shelo ba le'olam (a thing that has not yet come into existence), with R. Mana's query to R. Yudan and the analogy to a husband renouncing future inheritance from his wife. This probes the limits of vows and conditions regarding future, uncertain entities.

Readings

The Yerushalmi in Nazir 2:4:1-5:3 grapples with fundamental questions regarding the formation and annulment of vows, the role of intention, and the scope of linguistic declarations. The Rishonim and Acharonim illuminate these complexities, often highlighting the distinctions between the Yerushalmi's approach and that of the Bavli.

Penei Moshe (Nazir 2:4:1:1-5)

The Penei Moshe, as a foundational commentator on the Yerushalmi, offers crisp and essential insights into the Mishnah's rulings and the Gemara's chakirot.

Penei Moshe on Nazir 2:4:1:1: "מתני' הרי זה נזיר ואסור בכולן. ובהא כ"ע מודו מפני שהתנה על מה שכתוב בתורה וכל המתנה על מה שכתוב בתורה תנאו בטל."

Translation: "Mishnah: He is a nazir and forbidden everything. And regarding this, everyone agrees, because he stipulated against what is written in the Torah, and any stipulation against what is written in the Torah is void." Chiddush: The Penei Moshe immediately grounds the Mishnah's first clause in the universally accepted principle of tnai al mah shekatuv baTorah tna'o batel (a condition against that which is written in the Torah is void). This is crucial because it sets a baseline: certain conditions are inherently incapable of altering a Torah obligation. The nezirut takes effect unequivocally because its terms are divinely prescribed, rendering any human attempt to circumvent them through conditionality null and void ab initio. This implies that the kavana to be a nazir is sufficient, and the flawed condition is simply ignored. This clarity from the Penei Moshe, stating "כ"ע מודו" (everyone agrees), highlights that the machloket of R. Shimon and Rabanan is reserved for the subsequent clauses, not this fundamental principle.

Penei Moshe on Nazir 2:4:1:2: "הרי זה אסור. דיין ותגלחת וטומאה האסורין בנזיר הניזר מאחד מהן אסור בכלן."

Translation: "He is forbidden. For wine, shaving, and impurity, which are forbidden to a nazir, one who vows nezirut from one of them is forbidden in all of them." Chiddush: For the second clause, where one is ignorant of all prohibitions, the Penei Moshe explains the Rabanan's position: nezirut is a holistic obligation. One cannot cherry-pick which prohibitions to accept. Once one declares nezirut, even with partial knowledge, the full suite of issurim (prohibitions) applies. The chiddush here is the concept of nezirut as an indivisible unit. The act of vowing nezirut (הפלאה) itself brings with it the entire package of prohibitions, regardless of the individual's subjective awareness of each detail. This contrasts with R. Shimon's view, as we will see.

Penei Moshe on Nazir 2:4:1:3: "ור"ש מתיר. דקסבר אינו נזיר עד שיזיר מכלן."

Translation: "And R. Shimon permits. For he holds that one is not a nazir until he vows nezirut from all of them [prohibitions]." Chiddush: R. Shimon's radical departure is explained by the Penei Moshe: for him, nezirut is not activated unless one has explicit kavana to accept all its prohibitions. If one is ignorant of even one core issur, the vow is fundamentally flawed and does not take effect at all. This highlights a profound machloket on the nature of nedarim: are they primarily about the linguistic declaration (כ"ע מודו) or about the full, conscious acceptance of all implications (ר"ש)? R. Shimon's stance suggests a higher bar for gmirat da'at (finality of intent) in nedarim than Rabanan.

Penei Moshe on Nazir 2:4:1:4: "או מפני שאני קובר את המתים. וצריך אני להטפל בהן ה"ז מותר דהוי בכלל נדרי שגגות והוא אחד מארבעה נדרים שהתירו חכמים."

Translation: "Or because I am an undertaker, and I need to attend to them. He is permitted, for this falls under nidrei shogegot (vows made in error) and is one of the four vows the Sages permitted." Chiddush: Here, the Penei Moshe clarifies Rabanan's leniency in the third clause. This scenario is categorized as nidrei shogegot, where the vow was made under a mistaken assumption that Chazal would permit it due to a critical need (e.g., medical, professional). Such vows are among those the Sages "permitted" – meaning they are easily annulled or even considered void ab initio due to the fundamental error. This is not ignorance of halakha (as in the second clause), but a belief that one's specific circumstances warrant an exception. For Rabanan, such a profound error in judgment regarding one's ability to keep the vow constitutes a valid petach (opening for annulment).

Penei Moshe on Nazir 2:4:1:5: "ור"ש אוסר. דסבר ארבעה נדרים שהתירו חכמים צריכים שאלה לחכם ואין הלכה כר"ש בהני תרי בבי דמתני'."

Translation: "And R. Shimon forbids. For he holds that the four vows the Sages permitted require asking a chakham, and the halakha is not like R. Shimon in these two clauses of the Mishnah." Chiddush: The Penei Moshe explains R. Shimon's stringency in the third clause. While Rabanan consider the vital need an automatic petach, R. Shimon maintains that even for nidrei shogegot, explicit annulment by a chakham is required. The vow is not automatically voided by the mistaken assumption. This reveals R. Shimon's consistent stringency regarding the formal mechanism of hatarat nedarim (annulment of vows). His chiddush here is that gmirat da'at is sufficient to make the vow binding, even if based on a flawed premise, until formally revoked. Importantly, the Penei Moshe also provides a psak (ruling) that halakha does not follow R. Shimon in these last two clauses of the Mishnah, signaling the prevailing view.

Korban HaEdah (Nazir 2:4:1:1-3)

The Korban HaEdah, often supplementing the Penei Moshe, also provides succinct explanations, particularly noting where the Gemara will elaborate.

Korban HaEdah on Nazir 2:4:1:1: "מתני' הרי זה נזיר ואסור בכולם. בגמרא מפרש טעמא."

Translation: "Mishnah: He is a nazir and forbidden everything. The Gemara explains the reason." Chiddush: Similar to the Penei Moshe, the Korban HaEdah acknowledges the Mishnah's ruling. However, its chiddush lies in indicating that the ta'ama (reason) is not immediately obvious from the Mishnah's wording alone, and the Gemara will delve deeper into why the condition is void. This points to the Gemara's discussion of R. Meir's tnai kaful or R. Yehudah ben Tema's view on impossible conditions.

Korban HaEdah on Nazir 2:4:1:2: "אבל איני יודע שהנזיר אסור ביין ה"ז אסור ביין. דיין ותגלחת וטומאה הנודר מאחת מהן אסור בכולן הלכך לא הוי פתח."

Translation: "But I did not know that a nazir is forbidden wine, he is forbidden wine. For wine, shaving, and impurity, one who vows nezirut from one of them is forbidden in all of them, therefore it is not an petach (opening for annulment)." Chiddush: This comment reinforces the Penei Moshe's explanation for Rabanan's stance in the second clause. Ignorance of a specific prohibition within nezirut does not constitute a petach. The underlying principle is that nezirut is a package deal; once the general vow is made, all its inherent prohibitions are activated. The absence of full knowledge is not an "opening" for annulment because the declaration itself carries the weight of the mitzva's full scope.

Korban HaEdah on Nazir 2:4:1:3: "הרי זה מותר. בגמרא מפרש טעמייהו."

Translation: "He is permitted. The Gemara explains their reason." Chiddush: Again, the Korban HaEdah points to the Gemara for the full reasoning of the Rabanan's leniency in the third clause. This suggests that the nuanced distinction between ignorance of halakha (second clause) and mistaken assumption about halakhic dispensation (third clause) requires deeper textual analysis, which the Gemara provides by introducing the concept of petach.

Rambam, Hil. Nezirus 1:12-13 & Hil. Nedarim 9:1-2

The Rambam, as the authoritative codifier, provides a halakhic framework that implicitly engages with these Yerushalmi sugyot.

Rambam, Hil. Nezirus 1:12-13:

"מי שאמר הריני נזיר על מנת שאשתה יין, הרי זה נזיר ואסור ביין, שכל המתנה על מה שכתוב בתורה תנאו בטל. וכן אם אמר הריני נזיר ולא הייתי יודע שהיין אסור לנזיר, הרי זה נזיר ואסור ביין." (Rambam, Hil. Nezirus 1:12-13) Chiddush: The Rambam definitively rules like the Rabanan in both the first and second clauses of our Mishnah. He reiterates the principle of tnai al mah shekatuv baTorah tna'o batel for the first case. For the second, he explicitly states that ignorance of the issur does not invalidate the nezirut. This aligns perfectly with the Penei Moshe and Korban HaEdah's interpretation of Rabanan's position, solidifying the idea that nezirut is a comprehensive obligation. The Rambam's concise wording indicates that gmirat da'at for the general concept of nezirut suffices, even if the individual lacks full knowledge of its detailed prohibitions.

Rambam, Hil. Nedarim 9:1-2:

"ארבעה נדרים התירו חכמים... והן נדרי שגגות, כגון מי שנדר על דעת שיהיה מותר לו מפני איזה צורך וראה שאינו מותר לו, זהו פתח לנדרו." (Rambam, Hil. Nedarim 9:1) Chiddush: Regarding the third clause, the Rambam rules like Rabanan that nidrei shogegot (vows made in error, such as believing chakhamim would permit a vital need) provide a petach for annulment. However, he implies that this petach still requires a chakham to actually annul the vow, rather than being automatically void. This is a subtle point. While the Yerushalmi for Rabanan seems to lean towards automatic permission ("הרי זה מותר"), the Rambam's framework for hatarat nedarim typically mandates a chakham. This might suggest a slight difference in how "הרי זה מותר" is understood – perhaps meaning "it can be permitted" rather than "it is permitted without further action." This is a point of potential friction between the Yerushalmi's phrasing and the Bavli's (and Rambam's) more formal hatara process. The Penei Moshe's statement "אין הלכה כר"ש בהני תרי בבי דמתני'" supports the Rabanan here but doesn't necessarily clarify whether hatara is automatic or requires a chakham.

Rashba, Nedarim 11b (Bavli Parallel)

The Rashba, in his commentary on the Bavli's parallel sugya, offers a nuanced understanding of R. Shimon's position that can inform our Yerushalmi analysis.

Rashba, Nedarim 11b s.v. "אמר רבי שמעון":

The Rashba explains R. Shimon's view on petach (opening for annulment) in the context of nidrei shogegot. He notes that R. Shimon differentiates between a shegaga that relates to the very essence of the vow's possibility (e.g., vowing to bring an offering that cannot be brought, as in Menachot 12:3, which is the Yerushalmi's reference point for R. Shimon's view), and a shegaga that relates to a mistaken assumption about halakhic permission for a valid vow. Chiddush: For R. Shimon, if one vows something that by its nature cannot be fulfilled according to halakha (like offering barley flour as a voluntary offering, which must be wheat flour), the vow is void ab initio because it's "לא כדרך המקריבים" (not in the manner of those who offer). This is his position in the second clause of our Mishnah: if one doesn't know all the prohibitions of nezirut, it's "not in the manner of nezirim," and the vow is invalid. However, in the third clause, where one knows the issur but mistakenly believes chakhamim will permit an exception, the vow is valid because it's conceptually possible. The error is not in the nature of the vow itself, but in the expectation of dispensation. Therefore, it requires a formal hatara by a chakham. The Rashba's analysis thus provides a coherent logic for R. Shimon's seemingly contradictory positions, showing that his leniency and stringency are rooted in a consistent conceptual framework regarding the nature of the vow and the type of error involved.

In summary, the Rishonim and Acharonim, particularly the Penei Moshe and Rambam, clarify that the halakha generally follows Rabanan in validating nezirut despite conditions against Torah law or ignorance of specific prohibitions. The more complex machloket arises in nidrei shogegot, where Rabanan are lenient due to the profound error constituting a petach, while R. Shimon demands a formal hatara. The Rashba helps us understand R. Shimon's nuanced consistency across these cases.

Friction

The most striking kushya in our sugya emerges from the Mishnah's portrayal of Rebbi Shimon's stance across its three clauses. In the first two cases, Rabanan rule stringently (the nazir is bound), while R. Shimon is lenient (the nazir is free). Yet, in the third case, their positions reverse: Rabanan are lenient (the nazir is permitted), and R. Shimon is stringent (the nazir is forbidden). This apparent inconsistency in R. Shimon's shitta demands rigorous explanation.

The Strongest Kushya: The Reversal of R. Shimon's Position

Let's delineate R. Shimon's positions:

1. "הריני נזיר על מנת שאשתה יין": The Mishnah states "הרי זה נזיר ואסור בכולן," implying everyone agrees the condition is void because it contradicts Torah law. While R. Shimon is not explicitly mentioned as disagreeing here, the Gemara (Nazir 2:4:5) later suggests that R. Shimon would declare him free, drawing a parallel to his view in Menachot 12:3 regarding an offering "not according to the way of offerers" ("שלא כדרך המקריבין"). If one stipulates against a Torah law, it's not a proper nezirut, and therefore, he's free.
2. "לא הייתי יודע שהיין אסור לנזיר": Here, R. Shimon explicitly permits him ("ורבי שמעון מתיר"). His reasoning, as explained by Penei Moshe (Nazir 2:4:1:3), is "אינו נזיר עד שיזיר מכלן" – one is not a nazir unless he vows nezirut from all its prohibitions. Ignorance of a core prohibition means the kavana for a complete nezirut was lacking.
3. "סבור הייתי שהחכמים מתירין לי מפני שאיני יכול לחיות בלא יין, או מפני שאני קובר את המתים": This is where the reversal occurs. Rabanan permit him ("הרי זה מותר"), while R. Shimon forbids him ("ורבי שמעון אוסר").

The kushya is patent: R. Shimon consistently seems to advocate for leniency when there is a flaw in the kavana or a fundamental misunderstanding of the nezirut's nature (cases 1 and 2). Why, then, in case 3, where the individual is operating under a profound mistake ("סבור הייתי") that the Sages would permit him due to a vital need – a classic scenario for nidrei shogegot (vows made in error) – does R. Shimon become stringent? One would expect him to be lenient here too, perhaps arguing that such a fundamental error undermines the gmirat da'at (finality of intent) for the vow to take effect, or at least provides an easy petach (opening for annulment). The Gemara itself (Nazir 2:4:5) frames this kushya directly: "If it was because of an opening for the vow, does not the following state “he is permitted but Rebbi Simeon forbids”?"

The Best Terutz (or two)

The Yerushalmi itself provides the foundational terutz for R. Shimon's apparent inconsistency, rooted in a precise understanding of the nature of the shegaga and the mechanism of hatarat nedarim (annulment of vows).

Terutz 1: The Distinction Between Automatic Petach and Required Hatara

The Yerushalmi (Nazir 2:4:6) states: "Rebbi Simeon does not recognize it as an opening for the vow but the rabbis recognize it as an opening for the vow. Why? Because he connects his vow with his life." This is the crux.

For Rabanan:

• In the second clause ("לא הייתי יודע שהיין אסור לנזיר"), Rabanan are stringent. They view nezirut as a holistic entity: once the declaration is made, all prohibitions apply, regardless of partial ignorance. The gmirat da'at for the general nezirut is sufficient. Ignorance of the halakha itself is not a petach.
• In the third clause ("סבור הייתי שהחכמים מתירין לי"), Rabanan are lenient. They recognize this as a nidrei shogegot. The individual genuinely believed, based on a crucial life circumstance (medical necessity or profession), that their vow would be permissible. This mistaken assumption about halakhic dispensation constitutes a fundamental error that, for Rabanan, is an automatic "פתח לנדר." The vow is essentially nullified without needing to approach a chakham for formal annulment. The gmirat da'at was flawed from the outset because it was contingent on a false premise about halakhic allowance. The Gemara's phrase "מפני שהוא קושר את נדרו בחייו" (because he connects his vow with his life) emphasizes the severity of this error, making it a powerful petach.

For Rebbi Shimon:

• In the second clause ("לא הייתי יודע שהיין אסור לנזיר"), R. Shimon is lenient. His fundamental chiddush is that nezirut demands comprehensive kavana. If one is ignorant of even a single core prohibition, the vow is "שלא כדרך הנודרים" (not in the manner of those who vow) or "שלא כדרך המקריבים" (not in the manner of those who offer, as per Menachot 12:3). Thus, the nezirut never properly took effect.
• In the third clause ("סבור הייתי שהחכמים מתירין לי"), R. Shimon is stringent. Here, the individual knew the issur (e.g., wine is forbidden to a nazir). His error was not about the nature of the nezirut itself, but about the external possibility of a halakhic dispensation. For R. Shimon, this type of error, while significant, does not automatically void the vow. The gmirat da'at to be a nazir was present, even if based on a mistaken assumption. Therefore, the vow is binding, and if one wishes to be released, it requires a formal process of hatarat nedarim by a chakham, not an automatic petach. The Penei Moshe (Nazir 2:4:1:5) explicitly states R. Shimon's view: "ארבעה נדרים שהתירו חכמים צריכים שאלה לחכם" (the four vows the Sages permitted require asking a chakham).

In essence, the friction is resolved by understanding R. Shimon's consistent, albeit nuanced, approach: for him, a flaw in the internal definition or kavana of the vow itself (cases 1 & 2) renders it invalid ab initio. However, a flaw in external expectation about its permissibility (case 3) does not invalidate the vow; it merely creates grounds for hatara via a chakham. Rabanan, on the other hand, are more rigid about the initial activation of the vow (case 2) but more lenient about automatic annulment for severe nidrei shogegot (case 3).

Terutz 2: The Bavli's Perspective and Rav Assi

While the Yerushalmi provides its internal resolution, the Bavli (Nazir 11b) offers a similar, yet distinct, framing. The Bavli attributes the argument that one who thought chakhamim would permit him because he cannot live without wine is permitted, to Rav Assi. Rav Assi's reasoning is that this constitutes a petach. This parallels the Yerushalmi's Rabanan. The Bavli then presents R. Shimon's counter-argument, which, similar to the Yerushalmi, necessitates an actual chakham for annulment. The beauty of this parallel is how both Talmuds converge on the same conceptual distinction between the types of error and their implications for the vow's validity, even if phrased slightly differently. The Bavli's discussion reinforces the idea that R. Shimon is not necessarily more stringent per se, but rather places a greater emphasis on the formal procedural requirements for hatarat nedarim.

Ultimately, the apparent reversal in R. Shimon's position highlights a deep theoretical divide concerning the role of subjective intent (kavana), objective knowledge (yediah), mistaken assumption (shegaga), and procedural requirements (hatara) in the formation and dissolution of nedarim. The Yerushalmi's terutz clarifies that R. Shimon maintains a consistent standard: for the vow to take effect, the kavana must align with the full, proper halakhic definition of nezirut. Once that threshold is met, even a profound shegaga about its practical permissibility does not automatically void it; it merely provides an "opening" for a chakham to intervene.

Intertext

The sugya in Yerushalmi Nazir 2:4-5 is rich with conceptual parallels and cross-references, connecting it to fundamental principles across halakha.

Tanakh: The Essence of Nezirus

The very foundation of nezirut lies in Numbers 6:2: "איש או אשה כי יפליא לנדר נדר נזיר להזיר ליהוה" ("If a man or woman shall clearly pronounce a vow, the vow of a nazir, to consecrate himself to the Lord"). The phrase "כי יפליא" – "clearly pronounce" or "make distinct" – is crucial. For R. Shimon, this might imply that the kavana must be clear and complete for all aspects of nezirut. If one is ignorant of a core prohibition (e.g., wine), then the vow was not "clearly pronounced" in its full sense, hence it is invalid (Nazir 2:4:1, second clause: "ורבי שמעון מתיר"). Rabanan, conversely, might argue that "כי יפליא" refers to the general declaration of nezirut, and the details are inherent to the institution, thus binding regardless of full subjective knowledge. This scriptural root provides the backdrop for the profound machloket on the nature of gmirat da'at in nedarim.

Bavli Nazir 11a-b: A Parallel Universe

The Bavli's parallel sugya in Nazir 11a-b offers invaluable comparative insights, often illuminating or diverging from the Yerushalmi's lines of inquiry.

• R. Shimon's Stringency/Leniency: The Bavli (Nazir 11b) echoes the Yerushalmi's kushya regarding R. Shimon's seemingly contradictory stances. It attributes the Rabanan's leniency in the third clause ("סבור הייתי שהחכמים מתירין לי") to Rav Assi, who states that such a situation creates a petach (opening for annulment). The Bavli then presents R. Shimon's counter-argument, consistent with the Yerushalmi, that such a petach still requires a chakham for formal hatara. This demonstrates a common conceptual framework, even if the attributions differ. The Bavli's discussion of menachot 12:3 ("שלא כדרך המקריבים") also strongly parallels the Yerushalmi's explanation for R. Shimon's leniency in the second clause, where the vow is fundamentally flawed.
• "אף אני" and its Scope: The Bavli (Nazir 11b) also addresses the "אף אני" sugya from our Yerushalmi's second Mishnah. It explicitly states that "אף אני" refers only to the primary nezirut vow, not to additional stipulations (like the number of days or the obligation to shave another nazir), unless explicitly re-declared. This supports R. Yose's inference in the Yerushalmi (Nazir 2:5:2) that "I also" might only refer to part of the sentence, particularly for added terms. This Bavli parallel is critical for understanding the precise linguistic scope of nedarim.

Tosefta Gittin 5:12 & Bavli Gittin 84a: Impossible Conditions

The Yerushalmi (Nazir 2:4:3) explicitly references the Tosefta and Bavli Gittin regarding R. Yehudah ben Tema's view on impossible conditions.

"This is your bill of divorce, on condition that you not fly in the air, that you not cross the Sea on your feet, that is a bill of divorce. On condition that you fly in the air, that you cross the Sea on your feet, that is no bill of divorce; Rebbi Jehudah ben Tema said, it is a bill of divorce." (Yerushalmi Nazir 2:4:3, citing Tosefta Gittin 5:12, Bavli Gittin 84a) This parallel is used to explain the first clause of our Mishnah, where a nazir stipulates against Torah law. For R. Yehudah ben Tema, an impossible condition is treated as if it were fulfilled, or simply ignored, allowing the primary act (the get or the nezirut) to take effect. This provides an alternative explanation to R. Meir's tnai kaful for why the nezirut is valid in the first case. It underscores the concept that certain conditions are so absurd or impossible that they cannot truly impede the primary intention of the act.

Yerushalmi Ketubot 9:1:4: Davar Shelo Ba Le'olam

The final chakira in our Yerushalmi sugya (Nazir 2:5:3) concerns making a condition on "things not yet in existence" (davar shelo ba le'olam), drawing a direct parallel to a discussion in Yerushalmi Ketubot 9:1:4.

"If he wrote to her, 'I shall have nothing to do with the properties which you might inherit in the future.' May a person make a condition on things not yet in existence?" (Yerushalmi Nazir 2:5:3, citing Yerushalmi Ketubot 9:1:4) This intertextual link is profound. It connects the arcane rules of nedarim to broader principles of dinei mamonot (monetary law) and contracts. The general halakhic principle is that one cannot make a kinyan (acquisition) or a binding condition on something that does not yet exist and whose existence is not guaranteed (e.g., future crops, future inheritance). The question here is whether an obligation (like paying for future nezir sacrifices) falls under the same strictures as a kinyan. If one cannot obligate oneself for davar shelo ba le'olam, then a vow to pay for a nazir who will only make his vow in the future would be problematic. This highlights the rigorous logical framework applied across different areas of halakha.

These intertextual references demonstrate how the Yerushalmi's analysis of nezirut is not isolated but rather deeply embedded in a web of broader halakhic principles concerning nedarim, conditions, contractual obligations, and the interpretation of language.

Psak/Practice

The sugya in Yerushalmi Nazir 2:4-5, when viewed through the lens of psak, reveals several key principles governing nedarim and nezirut.

First Mishnah: Conditional Nezirut and Ignorance

1. Condition Contradicting Torah Law: The psak definitively follows the unanimous opinion (as per Penei Moshe Nazir 2:4:1:1) and Rabanan that "כל המתנה על מה שכתוב בתורה תנאו בטל" (any stipulation against what is written in the Torah is void). Therefore, if one says, "I am a nazir on condition that I may drink wine," the nezirut takes effect, and the condition is disregarded. The Rambam (Hil. Nezirus 1:12) codifies this directly.
2. Ignorance of Neziritic Prohibitions: The psak is like Rabanan (and against R. Shimon) that even if one declares nezirut without knowing all its prohibitions (e.g., wine is forbidden), the nezirut is valid, and all prohibitions apply. The Rambam (Hil. Nezirus 1:13) also rules this way. The general declaration of nezirut is considered sufficient gmirat da'at for the entire package of prohibitions inherent to the mitzva.
3. Mistaken Assumption of Halakhic Dispensation (Nidrei Shogegot): Here, the psak follows Rabanan (and against R. Shimon) that if one made a vow based on a mistaken assumption that chakhamim would permit it due to a vital need (e.g., medical, professional), this constitutes a "פתח לנדר" (an opening for annulment). The Penei Moshe (Nazir 2:4:1:5) explicitly states, "אין הלכה כר"ש בהני תרי בבי דמתני'" (the halakha is not like R. Shimon in these two clauses of the Mishnah), referring to the second and third cases. However, while Rabanan in the Yerushalmi suggest this might be an automatic permission ("הרי זה מותר"), the established halakha (as per Rambam, Hil. Nedarim 9:1-2, and Shulchan Aruch YD 228:1) is that even for nidrei shogegot, one must approach a chakham for formal hatarat nedarim. The shegaga creates the grounds for annulment, but the annulment itself requires a judicial process. Thus, the nezir would remain bound until a chakham annuls the vow.

Second Mishnah: Shared Neziritic Obligations

1. Scope of "I Also": The psak generally leans towards the understanding that "אף אני" (I also) refers only to the core nezirut vow, not to additional stipulations like the number of days or the obligation to shave another nazir, unless explicitly re-stated. This is the implication of R. Yose's derivation in the Yerushalmi (Nazir 2:5:2) and is explicitly stated in the Bavli (Nazir 11b). Therefore, if two individuals make such a vow, the second person becomes a standard 30-day nazir and must bring sacrifices, and also takes on an obligation to shave another nazir, but not necessarily the same number of days as the first, nor fulfilling the shaving obligation for the first person if their own nezirut was not simultaneous.
2. Chronology of Self-Fulfillment: The sugya indicates that if one vows to shave a nazir (i.e., pay for sacrifices) before becoming a nazir oneself, one can fulfill that obligation by applying it to one's own subsequent nezirut. This allows for efficient fulfillment of the obligation. However, the reverse is not true: if one is already a nazir, a later vow to shave a nazir cannot be retroactively applied to one's existing nezirut (Nazir 2:5:2).
3. Davar Shelo Ba Le'olam: The discussion of obligating oneself for future nezirim or making conditions on "things not yet in existence" (Nazir 2:5:3) touches on a fundamental halakhic principle. In dinei mamonot (monetary law), one generally cannot make a kinyan (acquisition) on davar shelo ba le'olam (Shulchan Aruch CM 210:1). However, in nedarim (vows), the principle is generally more flexible regarding future obligations. While one cannot dedicate animals for a non-existent nazir without the nazir's knowledge (Nazir 2:5:3), the vow to pay for the sacrifices of a future nazir is generally considered valid, akin to a nedavat Yisrael (a voluntary offering by an Israelite). The chakira in the Yerushalmi doesn't yield a definitive psak within the text, but the general understanding is that vows of obligation can extend to future, contingent events, unlike kinyanim.

Meta-Psak Heuristics

This sugya offers profound meta-psak heuristics:

• The Weight of Language vs. Intent: The debate between R. Shimon and Rabanan underscores the ongoing tension in halakha between the literal, declared word (lashon) and the underlying subjective intention (kavana). For nedarim, kavana is critical, but its scope and what constitutes a flaw in it are subject to intense scrutiny.
• Categories of Error: The sugya forces a categorization of errors: conditions against Torah law (void), ignorance of halakha (binding), and mistaken assumptions about halakhic dispensation (petach). Each type of error has distinct halakhic consequences.
• The Role of the Chakham: While halakha generally leans towards Rabanan in the first Mishnah, it emphasizes that even for petach, the formal intervention of a chakham is typically required, highlighting the structured nature of halakhic annulment rather than automatic release.

Takeaway

The Yerushalmi in Nazir 2:4-5 meticulously dissects the complex interplay of intent, knowledge, and declaration in nezirut vows, demonstrating that not all errors or conditions are treated equally, and requiring nuanced understanding of what constitutes a binding obligation. It also underscores the precise linguistic analysis demanded by halakha and the limits of obligating oneself for future, non-existent entities.
