Nedarim 59

Sugya Map

• Core Issue: The fundamental question of how and when a prohibited item, especially one that has been sown or grown, can be nullified (batel b'rov) by permitted items, or if it retains its prohibitory status due to being a davar sheyesh lo matirin (an item that can become permitted). This sugya explores the interplay between the source of the issur (e.g., karka, digon, neder) and its potential for bitul or heiter.
• Nafka Mina(s):
  • The halachic status of "growths" (gidulim) that sprout from a prohibited item (e.g., terumah onions, konam produce). Are gidulim treated as an extension of the issur, or can permitted gidulim nullify the original issur?
  • The distinction between various issurim (like konamot, terumah, ma'aser) regarding their capacity for bitul b'rov or their classification as davar sheyesh lo matirin.
  • The role of human "exertion" (yegia) in influencing the bitul of a prohibited item sown in the ground.
  • The nature of the chiyuv ma'aser – is it tied to the ground (karka) or to the act of "piling" (digon)? This impacts how ma'aser produce is treated when re-sown.
  • The unique status of konamot due to the mitzva la'ithashli aleihen (mitzva to request their dissolution) as articulated by R. Natan.
• Primary Sources:
  • Mishna Nedarim 57a: Defines konamot and the status of their gidulim.
  • Gemara Nedarim 59a: Discusses ma'aser and terumah in relation to gidulim and bitul, introducing the concept of davar sheyesh lo matirin.
  • Mishna Terumot 5:1: Deals with terumah falling into chullin and its bitul b'rov.
  • Mishna Shevi'it 6:3: Discusses onions from the sixth year sprouting in the Sabbatical year.
  • Devarim 14:22: The verse cited for chiyuv ma'aser.

Text Snapshot

The sugya opens with a core principle regarding ma'aser:

אמרי: מעשר דיגון הוא דקא גרים ליה, ולא קרקע. Nedarim 59a

This sets the stage for a critical distinction: the obligation of ma'aser is triggered by the act of digon (piling the produce), not by its growth in the ground (karka). This principle will be crucial in understanding how ma'aser produce, once tithed and then re-sown, is treated.

Rami bar Ḥama then challenges Rabbi Yannai's view (that terumah onions whose growths exceed their principal become permitted) from a Mishna on konamot:

מתיב רמי בר חמא ממתניתין: קונם פירות האלו עלי, או קונם על פי, או קונם לפי – אסור... ואפילו גידולי גידולין אסורין. Nedarim 59a, quoting Mishna Nedarim 57a

This Mishna states that if one vows "this produce is konam upon me," even "growths of growths" (gidulei gidulim) are forbidden if the seed does not cease. This implies that gidulei heter (permitted growths) do not nullify the issur, seemingly contradicting Rabbi Yannai.

Rabbi Abba offers a distinction:

אמר רבי אבא: קונמות שאני, כיון דאי בעי מתשיל עליהן, הוו להו כדבר שיש לו מתירין, ואין בטלין ברוב. Nedarim 59a

Konamot are different, says R. Abba, because "if one wishes, one can request their dissolution," making them "like an item that can become permitted (davar sheyesh lo matirin), and they are not nullified by a majority." This introduces the critical concept of davar sheyesh lo matirin.

The Gemara immediately challenges this distinction from terumah:

והא תרומה, דאי בעי מתשיל עליה, ובטלה ברוב! Nedarim 59a, referencing Mishna Terumot 5:1

Terumah, too, can be dissolved (by annulling the mistaken designation), yet it is nullified by a majority (100:1). This leads to a series of terutzim (answers) and kushyot (objections) to reconcile terumah with the davar sheyesh lo matirin principle, culminating in the final distinction:

אלא בשלמא קונמות מצוה לאיתשולי עלייהו, משום דרבי נתן, דאמר רבי נתן: כל הנודר כאילו בנה במה, וכל המקיימו כאילו מקטיר עליה. תרומה, מאי מצוה לאיתשולי עלייהו? Nedarim 59a

The final resolution is that konamot are unique because there is a mitzva to dissolve them (due to R. Natan's teaching about vows being akin to idolatry), whereas for terumah, there is no such mitzva to dissolve its designation. This qualitative difference in the "dissolution" makes konamot a true davar sheyesh lo matirin that is not batel b'rov.

Subsequently, the Gemara revisits the ma'aser discussion, citing R. Yochanan:

לגופו אמר רבי יוחנן: ליטרא בצל שעישר וזרעה – מתעשר מן הכל. Nedarim 59a

A litra of onions, once tithed and then sown, requires tithing from the entire resulting crop. Rav Ḥisda objects, arguing the original permitted litra should be subtracted. Rabba defends R. Yochanan by citing a Mishna from Shevi'it (6:3) about sixth-year onions sprouting in Shevi'it, where they are forbidden. The Gemara resolves this by distinguishing between exertion (yegia) and lack thereof, and finally distinguishes ma'aser itself:

מעשר שאני, דקרא אמר "עשר תעשר את כל תבואת זרעך היוצא השדה" – היתר, בני אדם זורעין; איסור, אין בני אדם זורעין. Nedarim 59a, citing Devarim 14:22

Ma'aser is different because the verse implies tithing all sown produce, and typically, people sow permitted seeds. Sowing forbidden (untithed) seeds is an anomaly, and thus the issur is not nullified, even with yegia, requiring proportional tithing from elsewhere.

Readings

Ran on the Initial Ma'aser Principle

The sugya begins with a fundamental statement regarding the obligation of ma'aser:

אמרי: מעשר דיגון הוא דקא גרים ליה, ולא קרקע. Nedarim 59a

The Ran (Rabbenu Nissim Gerondi) elucidates this principle, stating:

מעשר דיגון הוא דקא גרים ליה – שעל ידי דיגון מתחייב במעשר ולא ע"י קרקע. Ran on Nedarim 59a s.v. מעשר דיגון הוא דקא גרים ליה

The Ran's chiddush here is not merely a restatement but an emphasis on the nature of the obligation. He clarifies that the chiyuv ma'aser (obligation to tithe) arises specifically from the act of digon – the piling of the produce into a heap, indicating its readiness for storage and consumption. This is contrasted with karka (the ground), which merely facilitates growth. The Ran highlights that this distinction means the issur of tevel (untithed produce) is not intrinsically tied to the land. If the issur were tied to the land, one might argue that planting it back in the ground, causing new growth, could potentially neutralize the original issur or cause it to be absorbed by the heter of the ground. However, since the issur originates from the digon of the previous crop, and not from the karka where it is now planted, its status as tevel (or ma'aser sheni that has not been redeemed, etc.) remains distinct. This sets up a critical premise for later discussions on bitul gidulim: if the original issur wasn't tied to the karka, then planting it doesn't inherently nullify it. This understanding is foundational to the Gemara's eventual conclusion that ma'aser is shani (different) and not nullified even with yegia.

Rashi on Ma'aser and Terumat Ma'aser

Rashi, in his laconic yet precise style, further clarifies this initial ma'aser statement, particularly in the context of terumat ma'aser:

תריץ מעשר – תרומת מעשר דיגון הוא [דקא גרים]. ליה דלא מחייב בתרומת מעשר עד דמידגן והאי מאשתקד נידגנה הלכך מעשר עליה משל אשתקד ולא הוי איסורו על ידי קרקע הלכך לא הוי בטילתו ע"י קרקע. Rashi on Nedarim 59a s.v. תריץ מעשר

Rashi's chiddush is an elaboration on the Ran's point, applying it specifically to terumat ma'aser. He explains that one is not obligated in terumat ma'aser until digon. If the produce was nidgena (piled) in the previous year, then its ma'aser obligation stems from that past digon. Consequently, its issur (as tevel) is not al yedei karka (through the ground) in the present year. Therefore, its bitul (nullification) cannot occur al yedei karka either. This means that even if one plants an untithed onion (from last year's digon) and it sprouts new growth, the issur of the original onion, having arisen from a past digon, is not automatically absorbed or nullified by the act of planting in the ground and the subsequent heter of the new growth. Rashi's explanation reinforces the idea that the issur is a discrete entity, linked to the digon event, and not easily shed by mere association with karka or gidulim. This lays the groundwork for understanding why ma'aser has unique rules regarding bitul later in the sugya.

Tosafot on Konamot and Gidulei Gidulim

Rami bar Ḥama's challenge from the konamot Mishna (Nedarim 57a) is pivotal:

מתיב רמי בר חמא קונם פירות האלו עלי וכו' – לר' ינאי פריך דאמר לעיל בצל של תרומה שרבו גידוליו על עיקרו מותר דאלמא סבירא ליה דכולהו גידולין אע"פ שאין איסורן ע"י קרקע מעלין את העיקר ומשום הכי פריך ליה מקונמות דאין מעלין... Ran on Nedarim 59a s.v. מתיב רמי בר חמא קונם פירות האלו עלי וכו'

The Ran clarifies that the kushya is on R. Yannai, who held that terumah onions whose gidulim (growths) exceeded their ikar (principal) become permitted. This implies gidulim can ma'alin et ha'ikar (nullify the principal). But the konamot Mishna states that even gidulei gidulim (growths of growths) are forbidden "בדבר שאין זרעו כלה" (in an item whose seed does not cease). This seems to contradict R. Yannai.

The Tosafot delve into the reasoning behind this konamot ruling:

קונם שאני אוכל – לא אסר עצמו אלא בגופם והלכך בדבר שזרעו כלה הגידולין מותרין אבל בדבר שאין זרעו כלה אפילו גידולי גידולין אסורין אלמא גידולי היתר אינם מעלים את האיסור דאי מעלים גידולין אמאי אסורין הרי לא אסר עצמו אלא בגוף הפירות ולא אסר בגידולין וליתו גידולי היתר וליבטלו לעיקר אלא שמע מינה דגידולין לא מבטלין לעיקר הלכך העיקר מתפשט בגידולין ואסורין מטעם עיקר ועיקר חשוב ואינו בטל ונהי דודאי אינו מתיר ע"י קרקע כמו שביעית מכל מקום דמי לעל ידי קרקע התירו ולא שייך לשנויי דיגון הוא דקא גרים ליה. Tosafot on Nedarim 59a s.v. קונם שאני אוכל

The chiddush of Tosafot here is multifaceted. They explain that even when one only vows konam on the eating of the produce itself (קונם שאני אוכל), and not its gidulim, if the seed does not cease, the gidulim are still forbidden. Why? Because if gidulei heter (permitted growths) would nullify the issur (מעלים את האיסור), then the gidulim should be permitted, as the vow wasn't made on them. The ikar (original prohibited item) would simply be batel within the larger rov (majority) of permitted gidulim. Since the Mishna rules them forbidden, it implies that gidulim do not nullify the ikar. Rather, Tosafot posits a crucial svara: העיקר מתפשט בגידולין ואסורין מטעם עיקר ועיקר חשוב ואינו בטל – "the principal spreads into the growths, and they are forbidden on account of the principal, and the principal is significant and not nullified."

This chiddush introduces the concept that in "דבר שאין זרעו כלה" cases, the ikar is not merely diluted but pervades and extends itself into the new growth. The new growth isn't a fresh, entirely separate entity; it's a continuation and expansion of the original item, carrying its issur with it. This is a deeper explanation than simply saying "it's davar sheyesh lo matirin." It explains why it's not nullified even if the gidulim per se are heter. The issur isn't batel because the ikar remains "significant" (חשוב) and actively spreads. Tosafot also notes that this is similar to cases where karka permits (like Shevi'it), yet it's not a direct function of karka. This avoids the terutz of digon being the sole cause, acknowledging a more complex biological and halachic reality.

Ritvah (via Shita Mekubetzet) on the Konamot Challenge

The Ritvah, as quoted in the Shita Mekubetzet, offers a crisp summary of the kushya from konamot:

אלמא שמעינן (מסי) ממתניתין דגידולי היתר אין מעלין את האיסור דאי מעלין אם כן בסיפא שאיני אוכל ושאיני טועם גידולין אמאי אסורין בדבר שאין זרעו כלה והא לא אסר עצמו אלא בגופיהו דפירות אבל לא אסר עצמו בגידולין ואם כן ניתו גידולין דאינון בהיתר שלא אסר עצמו בהם וליבטלו לעיקר. הריטב"א ז"ל. Shita Mekubetzet on Nedarim 59a s.v. אבל בדבר שאין זרעו כלה

The Ritvah's chiddush here is his precise articulation of the logical steps of the kushya. He explicitly states that the Mishna implies that gidulei heter do not nullify the issur. If they did, then in a case where one only forbade the eating of the fruit (שאני אוכל), and not the gidulim themselves, why would the gidulim still be forbidden in "דבר שאין זרעו כלה"? The gidulim are permitted, and they are the majority; they should nullify the original ikar. The fact that they don't, according to the Mishna, proves that gidulim do not nullify the ikar. This clear exposition solidifies the kushya against the idea that gidulim can permit the ikar, setting the stage for Rabbi Abba's davar sheyesh lo matirin distinction. The Ritvah effectively distills the implicit reasoning of the Gemara and Tosafot into a direct logical proof from the Mishna.

Rabbi Abba's Davar Sheyesh Lo Matirin Principle

Rabbi Abba's response to the kushya from konamot introduces a pivotal concept:

אמר רבי אבא: קונמות שאני, כיון דאי בעי מתשיל עליהן, הוו להו כדבר שיש לו מתירין, ואין בטלין ברוב. Nedarim 59a

This statement is a chiddush in its own right, establishing that konamot, because they can be dissolved by a chacham, fall into the category of davar sheyesh lo matirin (an item that can become permitted). The halachic principle is that such items are never nullified by a majority (ein batelin b'rov). This principle stems from the idea that since a path to heter exists, one should pursue that path rather than relying on bitul, which is a passive form of heter. The item's inherent potential for permission elevates its status, making it too "important" to be simply swallowed by a larger quantity of permitted items. This is a broad halachic principle, but Rabbi Abba applies it specifically to konamot, offering a fundamental reason for their stringent treatment regarding gidulim.

The Gemara's Final Distinction for Terumah

The Gemara's back-and-forth about terumah culminates in its final, profound terutz:

אלא בשלמא קונמות מצוה לאיתשולי עלייהו, משום דרבי נתן, דאמר רבי נתן: כל הנודר כאילו בנה במה, וכל המקיימו כאילו מקטיר עליה. תרומה, מאי מצוה לאיתשולי עלייהו? Nedarim 59a

This is the Gemara's ultimate chiddush in distinguishing konamot from terumah regarding davar sheyesh lo matirin. The difference is not merely the ability to seek dissolution, but the nature of that dissolution. For konamot, there is a mitzva (a positive obligation) to seek hatarat nedarim (dissolution of vows), based on Rabbi Natan's teaching that one who vows is like one who builds a bama (private altar, forbidden after the Temple was built), and one who fulfills it is like one who sacrifices on it. This likens vows to an act of idolatry or a severe transgression, making their dissolution a religious imperative. Therefore, the "potential for permission" for konamot is not just a pragmatic option but a commanded one. This elevates konamot to the full stringency of davar sheyesh lo matirin, meaning they are never nullified.

For terumah, however, even if one can nullify its designation (e.g., if it was mistakenly separated), there is no mitzva to do so. It's a pragmatic choice, perhaps to retrieve a lost item, but not a religious imperative. Since there's no mitzva to dissolve it, its potential for heter is seen as less potent, and thus it can be nullified by a majority (in the proper ratios). This chiddush profoundly refines the definition of davar sheyesh lo matirin, adding the criterion of "mitzva to dissolve" as a necessary component for the full stringency of ein batel b'rov to apply. It moves beyond a purely legalistic potential for heiter to a moral and religious imperative.

Rav Ḥisda and Rabba on Ma'aser and Yegia

The Gemara then turns to the gufa (the matter itself) and R. Yochanan's statement:

לגופו אמר רבי יוחנן: ליטרא בצל שעישר וזרעה – מתעשר מן הכל. Nedarim 59a

Rabba states this halakha, but Rav Ḥisda objects: "The permitted part, to where did it go?" (ההיתר להיכן הלך?). Rav Ḥisda's chiddush (or rather, his kushya) is a common-sense query: if the original litra of onions was ma'user (tithed) and thus permitted, why should the entire new crop be tithed? The original litra should be exempt. This highlights a tension between the identity of the original seed and the new growth.

Rabba defends R. Yochanan by referencing the Shevi'it Mishna (Shevi'it 6:3) regarding sixth-year onions that sprouted in Shevi'it:

ממתניתין: בצל של שנה שישית שנפל עליו גשמים במוצאי שביעית והוריק – אם עליו שחורין, אסור. ירקין, מותר. Nedarim 59a, quoting Mishna Shevi'it 6:3

The Mishna states that if the leaves were black (meaning they derived sustenance from the original onion, which had Shevi'it sanctity), they are forbidden. If green (meaning they derived sustenance from the ground), they are permitted. Rabba argues, "If the leaves are black, why are they forbidden? Let us say: The permitted part, the original onion, to where did it go?" This is Rabba's attempt to show that even in cases where the ikar is forbidden, if it produces new growth (which is arguably permitted per se), the ikar isn't necessarily nullified.

The Gemara eventually distinguishes:

ואין כל היגיעה מבטלת ברוב? והא ליטרא מעשר טבל שזרעה, והוא יגע, ותנן: ואותה ליטרא משער לה עליה במקום אחר. Nedarim 59a

Here, the Gemara's chiddush is recognizing that yegia (human exertion, i.e., planting) is not an automatic determinant for bitul. It presents a case of ma'aser tevel (untithed ma'aser) where one exerts oneself to sow it, yet it's taught that one must still proportionally tithe for that original litra from another place. This demonstrates that even with yegia, the issur of ma'aser is not nullified.

The Gemara finally concludes:

מעשר שאני, דקרא אמר "עשר תעשר את כל תבואת זרעך היוצא השדה" – היתר, בני אדם זורעין; איסור, אין בני אדם זורעין. Nedarim 59a, citing Devarim 14:22

This chiddush relies on a derasha from the verse in Devarim. The verse implies tithing all produce that comes from sown seeds. This is interpreted to mean seeds that are typically sown – i.e., permitted seeds. When one sows forbidden seeds (like ma'aser tevel), it's an abnormal act, an issur. To penalize this act and ensure the chiyuv is met, the Sages decreed that the issur is not nullified, even with yegia. This creates a unique stringency for ma'aser, distinguishing it from other issurim and from the general rule that yegia might sometimes lead to bitul. It's a gezeirat haketuv coupled with a rabbinic enforcement to ensure proper tithing.

Friction

The Terumah Quandary: Davar Sheyesh Lo Matirin vs. Bitul B'rov

The most significant friction point in this sugya revolves around the concept of davar sheyesh lo matirin and its application, specifically when the Gemara tries to distinguish konamot from terumah.

The Strongest Kushya: Terumah as a Counter-Example

Rabbi Abba introduces the principle: "קונמות שאני, כיון דאי בעי מתשיל עליהן, הוו להו כדבר שיש לו מתירין, ואין בטלין ברוב" (Nedarim 59a). Konamot are davar sheyesh lo matirin because they can be dissolved, and therefore they are not nullified by a majority.

The Gemara immediately presents its strongest kushya:

והא תרומה, דאי בעי מתשיל עליה, ובטלה ברוב! Nedarim 59a

This kushya is potent because it directly challenges the premise of Rabbi Abba's distinction. The Mishna in Terumot (5:1) explicitly states that terumah can be nullified by a majority of 100:1 when it falls into chullin. Yet, the Gemara asserts that terumah also falls under the category of "אי בעי מתשיל עליה" – if one wishes, one can request its dissolution. For instance, if one mistakenly designated a se'ah of wheat as terumah, they could theoretically approach a beit din and declare that their intention was to designate terumah from a different batch, thus nullifying the original designation. Since both konamot and terumah share the characteristic of having a "matir" (a path to permission), why is terumah batel b'rov while konamot are not? This seems to undermine the very definition of davar sheyesh lo matirin as presented by R. Abba.

The Gemara proposes several terutzim, each met with a further kushya, highlighting the depth of the problem:

1. First Terutz: "במעשר ביר כהן" – We are dealing with terumah already in the possession of a priest. Once given to a priest, the owner can no longer request its dissolution.

   • Kushya: "אם כן, אימא סיפא: טהורה, נמכרת לכהן!" – But the seifa (latter clause) of the Mishna says pure terumah "is sold to a priest." This implies the terumah is still in the owner's possession, not yet given to a priest, and therefore dissolvable. This refutes the idea that the Mishna is dealing with terumah already in the priest's hands.

2. Second Terutz: "הכא במאי עסקינן, בישראל שירשה מבית אבי אמו כהן" – We are dealing with an Israelite who inherited terumah from his priestly maternal grandfather. The Israelite owns the terumah, but since he didn't designate it, he cannot request its dissolution.

   • Kushya: "והא תניא בסיפא: נמכרת לכהן, חוץ מדמי סאה זו!" – But the seifa also says it's sold to a priest except for the value of that se'ah. If the Israelite heir owns the terumah, why can he not collect its value? This implies the terumah does not belong to the Israelite heir in the same way, or at least he doesn't have full proprietary rights over its value in the context of sale. This kushya is strong because it shows that even this nuanced scenario doesn't fully fit the Mishna's details.

These rejected terutzim demonstrate the Gemara's rigorous pursuit of precision. The initial kushya remains formidable, pushing the Gemara to find a more fundamental distinction.

The Best Terutz: Mitzva La'ithashli Aleihen

The Gemara's ultimate terutz provides a profound differentiation:

אלא בשלמא קונמות מצוה לאיתשולי עלייהו, משום דרבי נתן, דאמר רבי נתן: כל הנודר כאילו בנה במה, וכל המקיימו כאילו מקטיר עליה. תרומה, מאי מצוה לאיתשולי עלייהו? Nedarim 59a

This is the Gemara's final and most incisive answer, differentiating konamot from terumah not by the ability to dissolve, but by the nature of that ability.

Explanation of the Terutz: For konamot, the act of vowing is likened by Rabbi Natan to building a bama (a forbidden private altar) and fulfilling it to offering sacrifices upon it. This teaching implies that vows, while permissible in certain contexts, carry a severe spiritual danger, potentially bordering on avodah zarah (idolatry) or at least a grave offense against the sanctity of the Temple cult. Consequently, there is a mitzva (a positive religious obligation) to dissolve them (mitzva la'ithashli aleihen) through a chacham. The potential for heter in konamot is thus not merely an option but a religious imperative, elevating their status to the highest degree of davar sheyesh lo matirin. The issur is so weighty, and its removal so necessary, that it cannot be passively ignored through bitul b'rov. One must actively pursue the heiter.

In contrast, for terumah, even if its designation can be dissolved (e.g., if it was mistakenly separated, as per the initial kushya), there is no mitzva to do so. It might be financially prudent or practically convenient to nullify a mistaken terumah designation, but it is not a religious obligation akin to avoiding the sin of a bama. Therefore, the terumah, while having a "matir" in a technical sense, does not possess the unique qualitative stringency of konamot that demands active dissolution. Thus, it remains susceptible to bitul b'rov under the prescribed conditions (100:1).

Why this is the "Best Terutz": This terutz is superior because it moves beyond mere technicalities of ownership or designation and delves into the underlying spiritual and ethical dimensions of the issur. It provides a coherent and profound reason for the halachic distinction, explaining why davar sheyesh lo matirin is not a monolithic category. The presence or absence of a mitzva to seek dissolution creates a qualitative difference in the "potential for permission," making one type of issur absolutely immune to bitul b'rov and the other not. It resolves the tension by refining the very definition of the principle, rather than relying on circumstantial details that are then disproven.

Intertext

Devarim 14:22 – The Source for Ma'aser and its Uniqueness

The Gemara's discussion about ma'aser and its resistance to bitul concludes with a unique derasha from a foundational verse:

מעשר שאני, דקרא אמר "עשר תעשר את כל תבואת זרעך היוצא השדה" (דברים יד, כב) – היתר, בני אדם זורעין; איסור, אין בני אדם זורעין. Nedarim 59a

This verse from Devarim 14:22 ("You shall surely tithe all the produce of your seed that is brought forth in the field") is the primary biblical source for the mitzva of ma'aser. The Gemara interprets "תבואת זרעך היוצא השדה" (the produce of your seed that is brought forth in the field) to imply that the Torah refers to normal agricultural practice. Normally, people sow permitted seeds. Sowing forbidden (i.e., untithed) seeds is an anomalous, undesirable act.

This derasha serves as a powerful intertextual link, establishing a unique stringency for ma'aser. It's not just a rabbinic gezeirah (decree) to ensure tithing; it's rooted in the very language of the Torah that outlines the mitzva. The implied norm of sowing permitted seeds gives rise to the halachic consequence that if one deviates from this norm by sowing untithed produce, the issur of that original produce is not easily shed. This is why, even with yegia (exertion, i.e., planting), ma'aser tevel is not nullified, and one must "proportionally tithe for it from produce in a different place" (משער לה עליה במקום אחר). This contrasts sharply with other issurim where yegia might be a factor in bitul. The very source of the mitzva dictates its unique stringency regarding bitul.

Rambam, Hilchot Nedarim 13:1-3 – Codifying Davar Sheyesh Lo Matirin

The principle of davar sheyesh lo matirin (an item that can become permitted) is a cornerstone of the sugya. The Rambam comprehensively codifies this principle and its application to vows in his Mishneh Torah:

כל דבר שאסרו אדם עליו בנדר או בשבועה, הרי זה אסור מדברי קבלה. ואין הנדר חל על דבר היתר אלא על דבר האסור. כיצד? אמר "שולחן זה עלי קורבן", הרי הוא אסור לו. אם ירצה להתיר נדרו, ילך אצל חכם ויתיר לו נדרו. Rambam, Hilchot Nedarim 13:1

ודבר שיש לו מתירין אינו בטל ברוב כלל, אלא לעולם עומד באיסורו עד שיותרו לו. Rambam, Hilchot Nedarim 13:3

The Rambam's discussion here provides a clear halachic framework for the Gemara's conclusion. He explicitly states that an item forbidden by a vow is assur, and if one wishes to permit it, they go to a chacham. More critically, he codifies the universal rule: "דבר שיש לו מתירין אינו בטל ברוב כלל, אלא לעולם עומד באיסורו עד שיותרו לו" (An item that can be permitted is never nullified by a majority at all; rather, it always remains forbidden until it is permitted). This directly reflects Rabbi Abba's chiddush in Nedarim 59a.

The Rambam, by establishing this as a general principle without explicitly invoking R. Natan's mitzva la'ithashli, might be understood in a few ways:

1. He implicitly accepts the Gemara's distinction that for konamot, the "matir" is of such a nature that it must be pursued.
2. He considers the mitzva to dissolve vows to be part of the inherent "matir" quality for konamot, elevating them above other issurim.
3. Perhaps for the Rambam, the very existence of a matir is sufficient, and the specific mitzva aspect articulated in the Gemara for konamot is merely one example of why certain matirim are potent enough to prevent bitul.

Nonetheless, the Rambam's codification underscores the enduring significance of Nedarim 59a in defining this critical halachic category. His comprehensive treatment of hilchot nedarim and the principle of davar sheyesh lo matirin is directly informed by this sugya, making it a vital intertext for understanding its practical implications.

Psak/Practice

The sugya in Nedarim 59a, with its intricate analysis of bitul and davar sheyesh lo matirin, lays down fundamental principles that reverberate throughout Halacha L'Ma'aseh.

The Principle of Davar Sheyesh Lo Matirin Ein Bo Bitul

The core practical takeaway is the firm rule that דבר שיש לו מתירין אינו בטל ברוב (an item that can become permitted is not nullified by a majority). This principle is explicitly codified in the Shulchan Aruch and its commentaries. For instance, Shulchan Aruch, Yoreh De'ah 99:5 states this rule clearly regarding various issurim. This means that if a prohibited item can be rendered permitted through a specific process (e.g., hatarat nedarim for vows, pidyon for ma'aser sheni, or waiting for terumah to become tahor), it cannot be simply overwhelmed and nullified by a larger quantity of permitted items. Instead, the process of heiter must be actively pursued.

The Gemara's refinement, distinguishing between konamot (where there's a mitzva la'ithashli) and terumah (where there isn't), is crucial for understanding the scope of this principle. Only those issurim with a matir that is either a mitzva to pursue, or is readily available and straightforward, are considered full-fledged davar sheyesh lo matirin for the purpose of bitul. For terumah, the matir (dissolving a mistaken designation) is not a mitzva, and thus it can be batel b'rov in the 100:1 ratio prescribed by the Rabbis. This nuance dictates which issurim require active heiter and which can rely on bitul.

Ma'aser and Gidulim

The Gemara's final conclusion regarding ma'aser (that untithed produce sown in the ground is not nullified, and the entire resulting crop must be tithed proportionally for the original untithed part) finds its way into Halacha L'Ma'aseh concerning agricultural laws. This is relevant for cases where one might inadvertently sow tevel or ma'aser sheni produce. The stringency rooted in the derasha from Devarim 14:22 ensures that the chiyuv ma'aser is not circumvented by replanting. This is generally codified in Hilchot Ma'aserot (e.g., Rambam, Hilchot Ma'aser 1:1, 1:4 regarding digon as the point of obligation, and the general stringency for tevel).

Meta-Psak Heuristics

1. Prioritizing Active Remediation: The sugya reinforces a meta-halachic heuristic: when a transgression or prohibition has a clear, active path to remediation (a matir), that path is preferred, and passive nullification (bitul) is often disallowed. This encourages proactive adherence to halacha rather than relying on fortuitous circumstances.
2. Qualitative vs. Quantitative Heter: The distinction between konamot and terumah highlights that not all "matirim" are equal. The Gemara introduces a qualitative assessment of the matir (is it a mitzva? what is its spiritual significance?) rather than just a quantitative one (does a matir exist?). This demonstrates the depth of halachic reasoning, looking beyond surface-level similarities to underlying theological and ethical implications.
3. The Role of Yegia (Exertion): While the Gemara initially explores whether yegia can cause bitul, it ultimately concludes that for certain issurim (like ma'aser), yegia does not override the inherent stringency derived from textual or rabbinic decree. This teaches that bitul is not merely a natural phenomenon but often subject to specific halachic parameters and gezeirot.

Takeaway

This sugya meticulously dissects the principles governing nullification (bitul) by distinguishing between various types of prohibitions (issurim) and the nature of their potential dissolution (matir). The crucial insight is that davar sheyesh lo matirin is not a monolithic category; its halachic potency to prevent bitul is profoundly influenced by whether there is a mitzva to pursue its dissolution, adding a unique ethical and spiritual dimension to the technical rules of bitul b'rov.
