Jerusalem Talmud Nedarim 6:8:1-10

Sugya Map: The Nuances of Vows and Categories of Things

This sugya in Yerushalmi Nedarim grapples with the fundamental principles governing vows, specifically how specific terms are interpreted when a vow is made. The core issue revolves around the distinction between a general term and a specific or qualified term, and its implications for the validity of a vow.

• Issue: The precise definition of terms in vows, particularly when a general term is used and a specific, related item exists. This includes cases where the specific item is a derivative, a variant, or known by a different name.
• Nafka Mina(s):
  • Halachic Scope of Vows: Determines whether abstaining from "wine" prohibits "apple wine," or abstaining from "oil" prohibits "sesame oil." This has direct implications for whether a vow is easily broken or rigorously adhered to.
  • Commercial Law: While not explicitly stated in the Nedarim portion, the underlying principle of specific versus general terms is crucial in contract law, as alluded to by the Bava Batra reference.
  • Agricultural Laws (Shemittah): The latter part of the passage, which seems to be a tangential inclusion, touches upon the definition of "vegetables" in the context of Shemittah laws and importations.
  • Calendar Intercalation: A significant portion of the text delves into the intricate laws and historical practices surrounding calendar intercalation, its conditions, and the authority for its declaration. This connects to the concept of defining "the year" and its temporal boundaries.
  • Ritual Purity and Temple Service: The discussion of Hezekiah's actions and the Temple's purification touches on the practical implications of definitions and timing in matters of ritual purity.
• Primary Sources:
  • Yerushalmi Nedarim 6:8
  • Mishnah Nedarim 6:6 (implied by the Yerushalmi's discussion)
  • Tosefta Shevi'it 6:4 (referenced for the halakha regarding leeks)

Text Snapshot

Mishnah:

If somebody vows not to use wine, he is permitted apple wine. Not oil, he is permitted sesame oil. Not honey, he is permitted date honey. Not vinegar, he is permitted winter grape vinegar. Not leeks, he is permitted field leeks. Of vegetables, he is permitted field vegetables, because that is an accompanying name.

Yerushalmi:

“Not leeks, he is permitted field leeks.” This is [only applicable] where one does not call field leeks karshen (leeks). But [if] in a place one does call field leeks karshen, then it is forbidden. Just in that case is it needed, even in a place where one calls field leeks karshen: “Not leeks, he is permitted field leeks.”

Yerushalmi (cont.):

“Not vegetables, he is permitted field vegetables because this is an accompanying name.” We have stated concerning that: “He who makes a vow to abstain from vegetables in the Sabbatical [year] is also forbidden field vegetables.” Rebbi Crispus stated the reason in the name of Rebbi Ḥanina ben Gamliel: That means, as long as Rebbi did not permit to import vegetables into the Land. But since Rebbi permitted to import into the Land there is no difference between the Sabbatical and the remaining years of the Sabbatical cycle. Rebbi Yose bar Ḥanina says, endives are important enough to become impure as food in the Seventh year. That means, as long as Rebbi did not permit to import vegetables into the Land. But since Rebbi permitted to import vegetables into the Land there is no difference between the Sabbatical and the remaining years of the Sabbatical cycle.

Dikduk/Leshon Nuance:

• "שם לווי" (Shem Lavui / Accompanying Name): This phrase, appearing in the Mishnah and explained in the Yerushalmi, is central. It signifies a name that qualifies or specifies a more general term. For instance, "field leeks" (כרשין שדה) is a shem lavui for the general category of "leeks" (כרשין). The Yerushalmi clarifies that the Mishnah's leniency applies when the specific name is not the common term. If "field leeks" is the everyday name for karshen in a locale, then a vow against karshen would include them.
• "כרשין" (Karshen): The Yerushalmi directly addresses the leeks example. It contrasts the situation with the other items (wine, oil, honey, vinegar). For those, the distinction is between a general category and a derived product or a different variety. With leeks, the issue is whether the common name (karshen) encompasses a specific type (karshen sadeh). The Yerushalmi states the Mishnah is only necessary when the common name is not uniformly applied to the specific type.
• "ירקות שדה" (Yerakot Sadeh / Field Vegetables): The Yerushalmi's discussion of "field vegetables" introduces a layer of complexity related to import and the Sabbatical year. The statement that "field vegetables" is an accompanying name seems to imply it's a sub-category. However, the subsequent discussion by Rebbi Crispus and Rebbi Yose bar Ḥanina connects it to import regulations and the concept of impurity during Shemittah, suggesting a broader, perhaps even commercial, connotation. The phrase "as long as Rebbi did not permit to import vegetables into the Land" is crucial, indicating that the classification of "field vegetables" and their permissibility might have changed based on rabbinic rulings regarding inter-regional trade.
• Intercalation Terminology: The latter part of the Yerushalmi is rife with specialized terms related to calendar intercalation: "intercalates for a year" (מעברים שנה), "Sabbatical" (שביעית), "year after the Sabbatical" (מוצאי שביעית), "Nisan" (ניסן), "Adar" (אדר), "Second Adar" (אדר שני), "New Year's Day" (ראש השנה), "impurity" (טומאה), "Passover" (פסח), "Second Passover" (פסח שני). These terms highlight the technical nature of calendar adjustments and their potential impact on religious observance.

Readings

1. Penei Moshe on Yerushalmi Nedarim 6:8:1:1

Translation: "The Mishnah states: 'Permitted with apple wine.' This is because it has an accompanying name (shem lavui), it is not called simply 'wine'."

The Penei Moshe, in his commentary on the Yerushalmi Nedarim, anchors the Mishnah's ruling in the principle of nomenclature. He explains that when a vow is made against a general term like "wine" (יין), the vow only encompasses that which is unequivocally and solely identified by that general term. If a specific type of wine exists, like "apple wine" (יין תפוחים), which is distinct from grape wine and possesses its own qualifying name, it is not subsumed under the general vow. The key is the presence of an accompanying name – a descriptor that differentiates it from the generic substance. This "accompanying name" serves as a boundary, defining the scope of the vow. If the vow was intended to include all fermented beverages, it should have been phrased more broadly. Since it was specific to "wine," and "apple wine" has its own distinct appellation, the vow does not extend to it. This approach emphasizes the precise language used in vows and the importance of recognizing distinct categories even within seemingly similar items. The Penei Moshe's interpretation suggests a rigorous textual analysis of the vow itself, looking for qualifiers that might exempt certain items.

2. Korban HaEdah on Yerushalmi Nedarim 6:8:1:1

Translation: "The Mishnah states: 'From the oil, permitted with sesame oil.' This implies that the default 'oil' is olive oil. Therefore, if one is accustomed to sesame oil, then sesame oil is also forbidden. And so it is with all the items mentioned in our Mishnah."

The Korban HaEdah offers a nuanced perspective, introducing the concept of local custom and default assumptions into the interpretation of vows. He disagrees with a simplistic application of the shem lavui principle as merely a linguistic distinction. Instead, he posits that the default understanding of a general term like "oil" (שמן) is context-dependent. In a place where olive oil is the standard and exclusively used, then "oil" refers to olive oil. However, if in a particular locale, sesame oil is commonly used, then "oil" might encompass sesame oil. The Korban HaEdah explicitly states that this is not merely about linguistic differentiation but about the prevailing practice ("במקום שמסתפקין"). Therefore, if one vows against "oil," and their usual practice involves sesame oil, then sesame oil is also forbidden. This introduces a crucial element of minhag hamakom (local custom) into the halachic interpretation of vows. The Korban HaEdah extends this logic to all items in the Mishnah, implying that the specific examples provided are illustrative of a broader principle that considers the common usage and availability of substitutes in a given community. This interpretation highlights the practical, lived reality of individuals and their communities as a factor in determining the scope of vows.

3. Mishneh Torah, Hilchot Nedarim 9:14 (Rambam)

Translation: "When a person takes a vow [not to partake of grapes], he is permitted to partake of wine, even fresh wine. Even though the wine tastes the same as grapes, since it is called by a different name, it is not considered in the same category... [The rationale for all of these rulings is] that [the names of] all these substances have a modifier and [when] the person took the vow, he referred to the substance without a modifier."

The Rambam, in his codification of Jewish law, provides a clear and concise articulation of the underlying principle governing these vows. He emphasizes that the distinction between the vowed-against item and the permitted item lies in their names. For example, if one vows not to eat "grapes" (ענבים), they are permitted to drink "wine" (יין), even if the latter is derived from the former and may taste similar. The critical factor is that "wine" is a distinct name, often with a qualifier (like "apple wine" or "winter grape vinegar"), from the raw produce. The Rambam further elucidates this by stating that the vow is made against the substance without a modifier. Therefore, if the vow was against "wine," and the permitted item is "apple wine," the latter has a modifier ("apple") that distinguishes it from the generic "wine." This principle is applied consistently across all examples in the Mishnah. The Rambam's formulation is highly systematic, focusing on the linguistic and categorical differences that exempt items from a vow. His statement that "the substances produced by the fruit are considered as being different from the fruit itself" is a powerful summary of this principle, extending it beyond mere varietal differences to encompass derivative products.

4. Penei Moshe on Yerushalmi Nedarim 6:8:1:3 (Regarding Leeks)

Translation: "Permitted with kapelot (field leeks). [This refers to] a type of leek that grows in the Land of Israel and was not included in the general category of 'leeks'."

The Penei Moshe, when addressing the specific case of leeks (כרשין), clarifies the distinction. He explains that "field leeks" (kapelot or karshen sadeh) refers to a specific variety of leek that grows wild or in a less cultivated manner in the Land of Israel. The crucial point, according to the Penei Moshe, is that this specific variety was not considered part of the general category of "leeks" in common parlance or in the context of vows. This implies a distinction based on origin or cultivation method. If the vow was against "leeks" in general, and "field leeks" were considered a distinct, less cultivated type, then abstaining from the latter would not fulfill the vow. This interpretation highlights how even within a single species, perceived differences in origin, cultivation, or form could lead to distinct categorical classifications, impacting the scope of vows. The Yerushalmi's subsequent clarification that this is only true where karshen sadeh is not called karshen reinforces this; the distinctness is a matter of nomenclature and common understanding.

Friction

Friction 1: The Nature of "Accompanying Names" and Local Custom

Kushya: The Mishnah states that "Of vegetables, he is permitted field vegetables, because that is an accompanying name." The Yerushalmi then clarifies this leniency applies "where one does not call field leeks leeks." However, the Korban HaEdah introduces the principle of minhag hamakom (local custom), suggesting that if sesame oil is the common oil in a place, then a vow against "oil" would include sesame oil. This creates a tension: Is the determination of what is included in a vow based solely on linguistic distinction (shem lavui), or is it also influenced by local customs and the practical understanding of what constitutes a general category? If "field leeks" is indeed an accompanying name because it's a specific type, why would local custom override this linguistic distinction? For instance, if in one city, "field leeks" are commonly called "leeks," the Yerushalmi says the vow applies. But what if in another city, "sesame oil" is the common oil, yet the Mishnah permits it under a vow against "oil"? Doesn't this suggest a conflict between the linguistic principle and the practical reality of consumption?

Terutz 1 (Distinguishing Linguistic vs. Practical Categories): One approach to resolve this friction is to differentiate between the nature of the distinction. For items like wine, oil, honey, and vinegar, the distinction is between the raw produce/primary substance and a derived product or a different varietal. "Apple wine" is apple wine, not just "wine." "Sesame oil" is sesame oil, not just "oil." These are inherently different substances with distinct names. The shem lavui here refers to the qualifier that makes it a distinct category. The Mishnah's leniency applies because the vow was against the unqualified term.

However, with "leeks" and "field vegetables," the Yerushalmi seems to introduce a more subtle linguistic point tied to common parlance. The statement "where one does not call field leeks leeks" suggests that if the common term is applied to the specific type, then the vow is binding. This is not about a fundamentally different substance (like apple wine vs. grape wine) but about the application of a name.

The Korban HaEdah's point about minhag hamakom might be applicable to the primary understanding of a general term. If the vow is against "oil," and in a specific locale, the overwhelming default is sesame oil, then perhaps the vow is interpreted through that lens. However, this would be an exception to the general rule, applying when the very definition of the general term is shaped by custom. The Mishnah's examples, particularly the leeks, seem to focus on the inherent linguistic distinctiveness rather than solely on custom. The Yerushalmi's clarification on leeks emphasizes the name itself. If the name "karshen" is applied to karshen sadeh, then the vow applies. This suggests that the shem lavui principle is primarily about a distinct, qualifying name that sets it apart. When that qualifier is absent in the vow, and the general term is used, the leniency applies, unless the common usage blurs that distinction.

Terutz 2 (Hierarchical Application of Principles): Another approach is to see a hierarchy of principles. The primary principle is the linguistic distinction, the shem lavui. If an item has a distinct name, it's generally permitted. However, when it comes to agricultural produce like "vegetables" or even "oil," the concept of minhag hamakom might play a secondary role in defining the scope of the general term itself, particularly in cases of common usage.

For example, when one vows against "oil," the default is olive oil (as Korban HaEdah suggests). But if the community's primary source of oil is sesame, then "oil" in that community's lexicon might inherently include sesame oil. The Mishnah's examples are often illustrative of the general case, but halakha is sensitive to local realities. The Yerushalmi's clarification on leeks is crucial: the leniency holds only if "field leeks" are not commonly called "leeks." This implies that common nomenclature is paramount. If local custom dictates that "sesame oil" is "oil" in practice, then the vow against "oil" would indeed cover it, despite the existence of a distinct name like "sesame oil." The shem lavui principle would then be applied to situations where there is a clear linguistic and conceptual separation, not where custom has merged the categories. The Korban HaEdah's point, therefore, might be a refinement of the shem lavui principle, accounting for how local usage can influence the perceived distinctiveness of a name.

Friction 2: The Tangential Nature of the Intercalation Discussion and its Relevance to Vows

Kushya: The latter half of the Yerushalmi passage, beginning with "It was stated: 'One intercalates for a year neither in a Sabbatical nor in the year after the Sabbatical'...," seems to diverge significantly from the initial discussion on vows. It delves into complex issues of calendar intercalation, the authority of the Sanhedrin, historical precedents involving Hezekiah and Jeremiah, and the geographical locus of calendar determination (Judea vs. Galilee vs. Diaspora). How does this extensive discussion on calendar intercalation, with its intricate details about timing, purity, and authority, relate to the seemingly straightforward halachot of vows concerning specific food items? Is this a mere digression, or is there an underlying conceptual link?

Terutz 1 (The Concept of "Time" and its Definition): The connection might lie in the fundamental concept of "time" and how its definition, like the definition of substances, can be subject to rabbinic interpretation and decree. Vows are often tied to specific actions or abstentions within a defined temporal framework. The intercalation discussion is precisely about defining and adjusting that temporal framework.

Consider the vow "I will not eat fruit until the new year." The definition of "new year" is crucial. If the calendar is intercalated, the "new year" is pushed back. Similarly, vows related to agricultural cycles, like those pertaining to Shemittah, are intrinsically linked to the calendar. The Yerushalmi, by embedding this discussion within Nedarim, might be drawing a parallel between the precision required in defining the scope of a vow concerning substances and the precision required in defining the scope of time.

The argument that "one does not intercalate for a year before New Year's Day; if they did intercalate it would be invalid" speaks to the strictness of temporal boundaries, analogous to the strictness in defining the boundaries of a vow. The debate about intercalation due to impurity or for the diaspora highlights how external factors and practical considerations can necessitate adjustments to established definitions, mirroring how the practical realities of food availability and nomenclature (as discussed by Korban HaEdah) can influence the interpretation of vows. The entire discussion on intercalation, therefore, can be seen as an exploration of how halakha defines and adjusts fundamental temporal categories, a concept that resonates with the definition of categorical boundaries in vows.

Terutz 2 (The Authority to Define and Enforce): Another connection lies in the concept of rabbinic authority to define and enforce halachic norms. The intercalation discussion is replete with examples of the Sages grappling with, establishing, and even disputing the authority to make such crucial calendar decisions. This mirrors the authority of the rabbinic courts and the community in interpreting and enforcing vows.

The Yerushalmi's excursion into the historical debates about intercalation, from the authority of the Sanhedrin in Judea to the actions of figures like Ḥanania the nephew of Rebbi Joshua in the Diaspora, demonstrates the complex interplay of authority, geography, and practice in establishing communal halakha. This mirrors how, in the realm of vows, the interpretation of a vow is not a purely individualistic exercise but is guided by established rabbinic principles and, as per Korban HaEdah, potentially by community norms. The very act of intercalation is a communal act, a declaration that shapes the religious life of the community. Similarly, the interpretation of vows, while initiated by an individual, is ultimately guided by the collective wisdom and interpretation of the Sages. The passage, by juxtaposing these two seemingly disparate topics, may be subtly emphasizing that the ability to define and enforce precise boundaries – whether temporal or categorical – stems from the same source of rabbinic authority and interpretive acumen. The lengthy digression serves as an extended illustration of the meticulousness and authority required in defining and implementing communal halakha, a principle that underpins the interpretation of individual vows as well.

Intertext

1. Mishnah Nedarim 6:6

The Mishnah in Nedarim 6:6, which this Yerushalmi passage is directly commenting on and expanding, provides the foundational examples: "If one vows not to eat fruit, he is permitted wine. If he vows not to drink wine, he is permitted vinegar. If he vows not to eat olives, he is permitted olive oil. If he vows not to eat leeks, he is permitted field leeks." The Yerushalmi here then elaborates on the reasoning, particularly the concept of shem lavui (accompanying name), and introduces variations and complexities, especially regarding the leeks and vegetables. This direct intertextual link shows the Yerushalmi as a deepening and refining of the Mishnah's initial pronouncements, adding layers of interpretation and addressing potential ambiguities.

2. Bava Batra 90b-91a

The Yerushalmi Nedarim 6:8:3 (implicitly referenced by footnote 80) mentions the Bava Batra's discussion on commercial contracts. Specifically, the Bava Batra discusses a seller who contracts to sell "oil" and the buyer's expectation. In Babylonia, where olive trees were scarce, "oil" in a contract typically referred to sesame oil. This highlights a parallel principle: the interpretation of a general term in a legal context (be it a vow or a contract) is often informed by local custom and common understanding. While the Nedarim passage focuses on vows, the underlying logic that a general term can have a specific, context-dependent meaning is evident in both. The Bava Batra's practical application of this principle in commerce underscores its significance beyond the realm of personal vows.

3. Leviticus Rabbah 19:3 (on Shemittah and Imports)

The Yerushalmi's discussion regarding "field vegetables" and their permissibility during Shemittah, referencing Rebbi's allowance of imports, connects to broader discussions about agricultural laws and their application. Leviticus Rabbah, commenting on Leviticus 25:1-7 (the laws of Shemittah), also grapples with the practicalities of agricultural produce. While not directly about vows, the underlying concern for defining what constitutes permissible produce during the Sabbatical year, and how imports fit into this, echoes the Yerushalmi's concern for defining categories of food. The concept of "field vegetables" becoming a point of discussion for import regulations and purity status during Shemittah suggests that the classification of produce has implications beyond simple culinary use, touching on broader halachic frameworks.

4. Sanhedrin 11b-12a (and Tosefta Sanhedrin 2:5-7)

The extensive discussion in the Yerushalmi Nedarim 6:8 concerning calendar intercalation is a direct parallel to, and likely derived from, the discussions in Yerushalmi Sanhedrin and its accompanying Tosefta. These passages meticulously debate the conditions under which a year may be intercalated, the authority for doing so, and historical precedents. The Yerushalmi Nedarim incorporates this material, perhaps to draw an analogy between the precise definition of temporal boundaries (the calendar) and the precise definition of categorical boundaries (in vows). Both require careful interpretation, rabbinic authority, and consideration of practical circumstances. The inclusion of this material in Nedarim suggests a broader conceptual exploration of how halakha defines and enforces critical parameters, whether they be the timing of festivals or the scope of personal prohibitions.

5. Genesis Rabbah 68:11 (on "The God who decides")

The Yerushalmi Nedarim 6:8 concludes with a discussion of "the God who decides" (אֱלֹהִים גּוֹמֵר) and its application to a girl's age and legal standing, influenced by the court's decision to lengthen a month. This seems to be a metaphorical extension of the principle of judicial decision-making. Genesis Rabbah, commenting on Genesis 23:16 ("Abraham listened to Ephron... and Abraham weighed to Ephron the silver that he had named in the hearing of the sons of Heth..."), discusses the concept of gomel (deciding, completing). The Yerushalmi links this to the court's decision to intercalate, which effectively "decides" the duration of a month and thus impacts legal ages. This connection highlights how the power to make definitive rulings, whether regarding financial transactions, calendar adjustments, or even the legal status of individuals based on age, rests with the court, mirroring the rabbinic authority that interprets and enforces vows.

Psak/Practice

The halachic implications of this sugya are primarily found in the laws of nedarim (vows). The core principle established is that a vow made against a general term does not include a specific item with a qualifying name (shem lavui), unless local custom or common parlance merges the categories.

• Application of Vow Interpretation: If someone vows "not to eat fruit," they are permitted to eat "wine" (derived from fruit but with a distinct name), or "apple wine" (a specific type of wine). If they vow "not to eat oil," they are permitted "sesame oil" (a different type of oil), unless they live in a place where "oil" exclusively or predominantly refers to sesame oil. This principle is codified by the Rambam in Hilchot Nedarim 9:14, which reflects the Mishnah's ruling.
• The Role of Custom: The Korban HaEdah's insight that local custom can influence the interpretation of a general term is critical. This means that the psak in a specific case might depend on knowing the common usage in the locale of the person making the vow. For instance, if one vows not to drink "juice," and in their region, "juice" commonly refers to apple juice, then other types of juice might be permitted.
• The "Leeks" Example: The Yerushalmi's clarification on leeks ("Not leeks, he is permitted field leeks" only if field leeks are not commonly called leeks) emphasizes that if the specific item is commonly referred to by the general term, the vow is binding. This is a key heuristic: ascertain how the item is actually referred to in everyday language.
• Shemittah and Imports: The discussion on vegetables and imports during Shemittah, while seemingly tangential, touches upon how rabbinic rulings can alter the classification or permissibility of agricultural produce. If Rebbi's ruling on imports changed the status of certain "field vegetables," it implies that the definition of what is permissible can be dynamic, influenced by broader halachic authorities and practical considerations.
• Calendar Intercalation and Authority: The extensive discussion on intercalation, while not directly leading to a psak in Nedarim, reinforces the overarching theme of rabbinic authority in defining fundamental parameters. The ability of the Beit Din to intercalate a year impacts the timing of festivals and agricultural cycles, demonstrating a parallel power to define critical temporal boundaries, much like the interpretation of vows defines categorical boundaries. This meta-level understanding of rabbinic power is crucial for understanding how halakha functions.

Meta-Psak Heuristics:

1. Linguistic Precision: Always begin with the precise wording of the vow.
2. Categorical Distinction: Identify if the item in question has a distinct, qualifying name (shem lavui) that separates it from the general term used in the vow.
3. Local Custom Check: Investigate the common usage and availability of the item in the specific locale of the vow-maker. If the general term is commonly understood to include the specific item due to custom, the vow may apply.
4. Common Parlance: Ascertain if the specific item is commonly referred to by the general term. If so, the vow is likely binding.
5. Substance vs. Derivative: Recognize that derived products (e.g., wine from grapes, oil from olives) are generally considered distinct from the raw produce, especially when they have their own names.

Takeaway

The interpretation of vows hinges on the precise language used, distinguishing between general categories and specific, qualified items, a principle modulated by local custom and common parlance. This meticulous attention to nomenclature and context reflects the rabbinic commitment to defining boundaries with clarity, whether in personal prohibitions or communal calendar adjustments.
