Nedarim 59

Hook

This passage grapples with a seemingly straightforward question: when does a prohibition take effect and, crucially, when does it get undone? The non-obvious part is how the Gemara navigates the subtle distinctions between different categories of forbidden items – vows, tithes, and terumah – and how these distinctions hinge on the very nature of the prohibition and the possibility of its removal.

Context

To appreciate the depth of this discussion, we need to recall the foundational concept of bittul (nullification) in Jewish law. This principle allows a forbidden item to lose its prohibited status if it is mixed with a much larger quantity of permitted items. The halakha for bittul is most famously articulated in the context of terumah (priestly tithe) and ma'aser (tithe) and often involves a ratio of 1:60 or 1:100. However, as we'll see, the Gemara probes whether this principle applies universally or if certain types of prohibitions are inherently resistant to bittul. This relates to a broader theological and legal debate about the nature of divine commandments and human vows – are they absolute decrees, or can they be rendered void through specific legal mechanisms?

Text Snapshot

"The Sages of the Gemara say: With regard to tithe, the ground does not engender the obligation; placement of the produce in a pile engenders the obligation, as it is only at that point that one is obligated to tithe his produce. Therefore neutralization of the prohibition is not effected by planting it in the ground.

Rami bar Ḥama raised an objection to the opinion of Rabbi Yannai based on the mishna (57a): For one who says: This produce is konam upon me... it is prohibited to partake of the produce, or of its replacements, or of anything that grows from it. If he says: This produce is konam for me, and for that reason I will not eat it... it is permitted for him to partake of its replacements or of anything that grows from it. This applies only with regard to an item whose seeds cease after it is sown. However, with regard to an item whose seeds do not cease after it is sown, it is prohibited for him to partake even of the growths of its growths. Apparently, permitted growths do not neutralize the prohibition.

Rabbi Abba said: Konamot are different; since if he wishes to do so he can request that a halakhic authority dissolve the vows and render the objects of the vows permitted, their legal status is like that of an item that can become permitted, and its prohibition is not nullified by a majority of permitted items.

The Gemara asks: And isn’t there the case of teruma, in which if he wishes he can request that a halakhic authority dissolve the designation of the produce as teruma and yet it is nullified by a majority of permitted items? As we learned in a mishna (Terumot 5:1): A se’a of ritually impure teruma that fell into less than one hundred se’a of non-sacred produce must be left to decay... If it fell into one hundred se’a of non-sacred produce, its prohibition is neutralized.

The Gemara asks: If so, say the latter clause of that mishna: If the teruma mixed with the non-sacred produce was ritually pure, it may be sold to a priest... Rather, we are dealing with the case of an Israelite who inherited the produce from a member of the house of his mother’s father, who is a priest. The heir owns the teruma; however, since he was not the one who designated it as teruma, he may not request that the designation be dissolved.

The Gemara asks: But isn’t it taught in that latter clause of that mishna: It must be sold to a priest; however, the price must reflect the value of the entire mixture except for the value of that se’a of teruma that fell into the non-sacred produce, as the teruma belongs to the priest. If the mishna is referring to the case of an heir who owns the teruma, why can he not collect the value of that se’a as well, as it is his property?

Rather, say that there is another distinction between konamot and other cases where one may request dissolution by a halakhic authority. Granted, in the case of konamot, there is a mitzva to request that a halakhic authority dissolve them, due to the statement of Rabbi Natan, as Rabbi Natan said: Anyone who vows, it is as if he built a personal altar outside the Temple, and one who fulfills that vow, it is as though he burns an offering upon it. However, in the case of teruma, what mitzva is there to request that a halakhic authority dissolve its designation? Therefore, items forbidden by konamot are considered items that can become permitted, and teruma is not."

Insight 1: The Genesis of Obligation (Structure)

The opening lines establish a crucial distinction in how obligations are triggered. For ma'aser (tithe), the land itself doesn't create the obligation ("the ground does not engender the obligation"). Instead, it's the action of gathering the produce into a pile ("placement of the produce in a pile engenders the obligation"). This is a fundamental point about the legal status of agricultural produce. Before it's harvested and gathered, it's essentially in a state of potential, not yet subject to specific tithe laws. The act of forming a pile signifies the produce's readiness for use and, consequently, its liability for tithe.

This has significant implications for bittul (nullification). The Gemara states, "Therefore neutralization of the prohibition is not effected by planting it in the ground." This means that if produce that should have been tithed but wasn't, is then planted, the act of planting itself doesn't "neutralize" the underlying obligation in the way that mixing with a larger quantity of permitted produce would. The prohibition remains tied to the produce's status before planting. The commentaries, like Ran, explain this as digun (piling) being the trigger for the ma'aser obligation, not the earth itself. Rashi further clarifies that if the produce was already nidgan (piled) from a previous year, it's still obligated for ma'aser from that previous year, implying that the obligation is tied to the produce's state at a specific point in time, not continuously by the ground.

Insight 2: The Nature of Growth and Prohibition (Key Term: Gidulin - Growths)

The discussion then pivots to the concept of gidulin (growths) and how they relate to prohibitions, particularly in the context of vows (konamot). Rami bar Ḥama’s objection highlights a critical difference between two types of vows:

• "This produce is konam upon me": This vow makes the produce itself forbidden. If the produce produces new growth, the status of these growths is debated.
• "This produce is konam for me, and for that reason I will not eat it": This vow is framed as a consequence of the produce's forbiddenness, not a direct prohibition on the produce itself.

The mishna cited by Rami bar Ḥama introduces a distinction based on whether the "seeds cease" after sowing. For items like grains, where the original seed is consumed in the process of producing the new crop, the new growth is considered separate. However, for items like onions or garlic, where the bulb or clove can regrow and produce new shoots, the line between the original produce and its "growths" can blur.

The crux of Rami's objection is that for items whose seeds do not cease (like onions), even the growths of its growths are forbidden. This implies that permitted growths do not "elevate" or "neutralize" the original prohibition. If the original produce is forbidden, its subsequent growths inherit that prohibition, especially if the prohibition is deeply ingrained. Tosafot emphasizes that the prohibition on the produce extends to its growths, and if the original prohibition is strong, permitted growths can't dissolve it. This points to a fundamental principle: the nature of the prohibition matters. A direct prohibition on the item itself is more tenacious than a prohibition that is a consequence of another prohibition.

Insight 3: The 'Can Become Permitted' Principle (Tension)

The core tension emerges when Rabbi Abba distinguishes konamot from teruma. Rabbi Abba argues that konamot are different because "if he wishes to do so he can request that a halakhic authority dissolve the vows." This ability to seek dissolution makes the forbidden item akin to "an item that can become permitted." Because of this potential for permittedness, its prohibition is not easily nullified by a majority of permitted items. This is a crucial concept: the potential for permittedness acts as a shield against bittul.

The Gemara immediately challenges this by pointing to teruma. Teruma can also be dissolved under certain circumstances (e.g., if it was designated in error). Yet, the mishna in Terumot states that even teruma is nullified by a majority (specifically, one hundred se'a of non-sacred produce for one se'a of impure teruma). This creates a direct conflict: why are konamot resistant to bittul due to their potential for permittedness, while teruma, which also has a mechanism for permittedness, is not?

The Gemara then embarks on a complex analysis to resolve this tension, exploring various scenarios for teruma (priest's possession vs. Israelite heir) and the nuances of dissolution. The ultimate resolution points to a deeper distinction: in the case of konamot, there is a mitzvah (commandment) to seek dissolution, as articulated by Rabbi Natan, who equates vows to building an altar. This mitzvah of seeking dissolution imbues the vow with a special status, making it "an item that can become permitted." For teruma, however, while dissolution is possible, there isn't the same inherent mitzvah to do so. This lack of a positive imperative to seek dissolution makes teruma less inherently "capable of becoming permitted" in the same way as a vow, thus allowing it to be nullified by a majority. The Gemara is essentially saying that the intent and religious imperative surrounding the act of seeking dissolution plays a role in determining how a prohibition behaves.

Two Angles

Angle 1: The Intrinsic Nature of the Prohibition (Ran's Perspective)

Rabbi Yitzchak bar Sheshet Perfet, known as the Ran, often emphasizes the intrinsic nature of the prohibition itself. In his view, the distinction between konamot and teruma lies in the fundamental origin and purpose of the prohibition. For a konam vow, the prohibition is personal and self-imposed, albeit with significant halakhic weight. The ability to dissolve it stems from the recognition that human vows, while serious, are not absolute divine decrees. The mitzvah to seek dissolution, as highlighted by Rabbi Natan, underscores the Torah's preference for avoiding unnecessary personal asceticism. Therefore, such vows are seen as inherently amenable to correction and therefore more readily fall under the category of "items that can become permitted."

Ran would likely interpret the Gemara's discussion of teruma as dealing with situations where the teruma has already been definitively separated and designated. Once teruma is in the hands of a priest, or its status is irrevocably set within the system of priestly gifts, its potential for dissolution might be curtailed, or the mitzvah to dissolve it is less pronounced. The terumot mishna, where teruma is nullified, might be describing a scenario where the teruma's status is less absolute or where the mechanism for its dissolution is less emphasized than the mitzvah surrounding konamot. The key for Ran is the inherent potential for permittedness tied to the type of prohibition and the religious encouragement to rectify it.

Angle 2: The Practical Mechanism of Dissolution (Rashi's Perspective)

Rashi, on the other hand, often focuses on the practical and procedural aspects of halakha. His commentary on this passage would likely center on the availability and ease of the dissolution process. For konamot, Rashi would emphasize that the possibility of approaching a halakhic authority and obtaining a heter (permission) is readily available. The statement "if he wishes he can request" is paramount. This direct, accessible avenue to permittedness makes the vow's prohibition less absolute.

Regarding teruma, Rashi would dissect the scenarios presented in the mishna more granularly. If the teruma is in the possession of an Israelite heir who did not designate it, he owns it, but he cannot dissolve the teruma status himself. He must sell it to a priest. This procedural step, while leading to a form of permittedness for the non-sacred produce, doesn't involve the same direct personal act of dissolution as with a vow. The distinction then becomes about who can effect the dissolution and the directness of that process. Rashi might argue that the Gemara's debate about the heir's inability to reclaim the value of the teruma highlights that, in that instance, the teruma's status is somewhat fixed, making it less of an "item that can become permitted" in the same way as a vow whose dissolution is a direct personal action. The focus is on the practical pathways to resolving the prohibition.

Practice Implication

This passage profoundly shapes how we approach self-imposed restrictions and obligations. When we make a vow, whether it's a personal commitment to a diet, a habit, or a spiritual practice, this Gemara teaches that the very possibility of seeking counsel and obtaining a heter (dissolution) from a halakhic authority imbues that vow with a unique legal status. It's not just about the strength of our will, but about the recognized pathways within Jewish law to permit what was once forbidden.

In practice, this means that if we find ourselves struggling with a vow, the first step isn't necessarily to break it or despair, but to actively explore the possibility of seeking dissolution. This encourages a proactive engagement with Jewish legal frameworks, rather than a purely internal, potentially isolating struggle. It also implies that a vow taken with the understanding that it can be dissolved is, in a sense, less absolute and more integrated into the flexible system of Jewish law, making it more susceptible to eventual permittedness through proper channels. This contrasts with obligations like teruma or ma'aser, where the prohibition is divinely ordained and its dissolution operates under different, often more stringent, rules of mixture and nullification.

Chevruta Mini

Question 1

The Gemara posits that konamot are different because there's a mitzvah to seek their dissolution, unlike teruma. This raises a trade-off: on one hand, this mitzvah makes konamot more easily resolvable and less prone to bittul. On the other hand, does emphasizing the mitzvah to dissolve vows implicitly de-emphasize the importance of keeping one's word, creating a tension between personal integrity and halakhic flexibility?

Question 2

The discussion on teruma and its nullification grapples with scenarios like an Israelite heir possessing teruma. If the heir cannot dissolve the teruma status directly, and it's subject to bittul in mixture, does this imply that obligations tied to inherited property, where the original intent of the giver is removed, are inherently more susceptible to external forces like mixture than self-imposed vows? This poses a trade-off between the sanctity of inherited sacred status and the practical realities of communal law.

Takeaway

The susceptibility of a prohibition to nullification hinges on the inherent nature of the prohibition and the religious imperative to seek its dissolution, distinguishing personal vows from divinely ordained tithes.
