Nedarim 90
Sugya Map
The sugya in Nedarim 90a addresses the temporal and conceptual boundaries of hatarat nedarim (the dissolution of vows by a halakhic authority) and hafara (nullification by a husband). Specifically, the Gemara investigates whether these mechanisms can operate on a vow before it has formally taken effect (chaloos).
- The Core Issue: Can a sage (chacham) perform she’eilah (dissolution) on a conditional or suspended vow before the triggering condition is met? Similarly, can a husband nullify (mefer) his wife’s vow before its onset?
- The Nafka Minot (Practical Ramifications):
- Conditional Vows: If a person vows, "I am a nazir if I enter this house," can he seek dissolution from a Chacham before entering the house?
- Socio-Halakhic Rescue: If someone vows to avoid all worldly benefit if he marries, can a Chacham dissolve the vow prior to the marriage to prevent the vow from ever taking effect? Or must we force the marriage to trigger the chaloos, leaving him temporarily forbidden to benefit from the world?
- Primary Sources: Numbers 30:3, Isaiah 24:23, Job 5:12, and Nedarim 90a.

...ושרקיה טינא ואנסביה איתתא ואתייה לקמיה דרב חסדא...
"...And he smeared him with clay, and married him to a woman, and brought him before Rav Hisda..."
— Nedarim 90a:1
Linguistic and Grammatical Nuances
- "ושרקיה טינא" (And he smeared him with clay): The root ש-ר-ק means to coat, plaster, or smear. The passive/reflexive action here is highly unusual for a halakhic process. Why smear a petitioner with clay before bringing him to a sage? The commentators split on whether this is a physical barrier to prevent violation of a vow or a psychological tool to alter identity.
- "וחפרה הלבנה" (And the moon shall be confounded): Rabbi Natan derives his view that a husband cannot nullify a vow before it takes effect from Isaiah 24:23, homiletically reading chaferah (confounded/ashamed) as hafarah (nullification). The grammatical play links the physical existence of the moon to the ontological existence of the vow: just as the moon must exist to be confounded, the vow must exist (be chal) to be nullified.
- "לא יחל דברו" (He shall not profane his word): The Rabbis utilize Numbers 30:3 to establish that while the vower cannot profane his word, others (the Chacham) can. The word yachel (profane) shares a root with chaloos (taking effect), prompting a debate on whether the Chacham's power is structurally bound to a vow that is already chal.
Readings
To understand the mechanics of this sugya, we must unpack the dense commentary of the Rishonim. The debate over Rav Aha bar Rav Huna’s bizarre behavior—smearing his disciple with clay and forcing him to marry before bringing him to Rav Hisda—unveils two entirely different ways of conceptualizing the relationship between a vow, its chaloos, and its dissolution.
1. The Ran: The Metaphysical-Halakhic Shield and the Escape from Doubt
ושרקיה טינא - כדי להראותו שהוא צריך לבריות לאלתר לכבוס בגדיו וקסבר כי היכי דפליגי רבנן ורבי נתן בהפרה פליגי נמי בשאלה דרבי נתן נמי ס"ל בשאלה דאין חכם מתיר אא"כ חל הנדר ונהי דבמאי דפליגי ר' נתן ורבנן קיימא לן כרבנן דיחיד ורבים הלכה כרבים וכדבעינן למכתב קמן איהו לאפוקי נפשיה מפלוגתא הוא דעבד הכי...
Translation: "And he smeared him with clay — in order to show that he was immediately in need of people to wash his clothes. And he holds that just as the Rabbis and Rabbi Natan argue regarding nullification, they also argue regarding inquiry [to a sage]. For Rabbi Natan also holds regarding inquiry that a sage does not permit unless the vow has taken effect. And although in that which Rabbi Natan and the Rabbis argue we rule like the Rabbis—since the rule is that between an individual and a majority, the halakha is like the majority, as we will write ahead—he [Rav Aha] did this to remove himself from dispute..."
The Ran's Chiddush
The Ran Ran on Nedarim 90a:1:1 argues that Rav Aha bar Rav Huna operated under a strict meta-halakhic principle: la'afokei nafshei mi-pelugta (extricating oneself from halakhic doubt).
According to the Ran, the halakha actually follows the Rabbis, who hold that a Chacham can dissolve a vow before it takes effect. However, because Rabbi Natan holds that no dissolution can occur until the chaloos is active, Rav Aha did not want to rely on the lenient majority opinion in a matter of severe prohibitions (nedarim).
To satisfy all opinions, Rav Aha forced the vow to take effect by marrying the man off. But this created an immediate catastrophe: the moment the marriage occurred, the vow took effect, and the man was instantly forbidden to derive any benefit from the world—including wearing clothes!
To resolve this, Rav Aha smeared him with clay. The clay served as a physical, non-beneficial insulation, protecting him from the elements without violating the vow against wearing clothes. Once the chaloos was established under these protected conditions, they could safely approach Rav Hisda for hatarah according to all opinions.
2. Rashi: The Social-Psychological Disguise and Judicial Depth
ושרקיה טינא - טח פניו בטיט כדי שלא יכירהו רב חסדא כאילו היה אדם אחד מהם שנדר שלא ישא אשה כדי שיתיר לו דאפשר אילו היה מכירו לא היה מתיר לו:
מאן חכם למיעבד כי האי מילתא - שדקדק בכך שהשיאו אשה קודם שישאל על נדרו כדי שיחול הנדר עליו קודם שאלה דקסבר כרבי נתן דאמר לא יפר הואיל ולא חל הנדר דרבי נתן דיינא הוא ונחית לעומקא דדינא:
הכי נמי פליגי בשאלה - שאין נשאלין לחכם עד שיהא הנדר חל עליו:
Translation: “And he confused him and married him to a woman and smeared him with clay — he smeared his face with clay so that Rav Hisda would not recognize him, as if he were just some random person who vowed not to marry a woman so that he would permit it for him. For perhaps if he had recognized him, he would not have permitted it to him. Who is wise to do such a thing — that he was precise in this to marry him to a woman before he inquired about his vow, so that the vow would take effect upon him before the inquiry. For he holds like Rabbi Natan who said one cannot nullify since the vow has not taken effect, for Rabbi Natan was a judge and descended to the depths of the law. So too they argue in inquiry — that one does not inquire of a sage until the vow has taken effect upon him.”
Rashi's Chiddush
Rashi Rashi on Nedarim 90a:1:1 offers a completely different, highly pragmatic reading. The clay was not a halakhic insulation against the prohibition of wearing clothes; it was a physical disguise (shelo yakirehu).
Why did he need a disguise? Rashi introduces a realistic dynamic of the Beit Din: if Rav Hisda had recognized this young scholar, he might have refused to annul the vow as a disciplinary measure, or out of anger that a student of such stature had made such an irresponsible vow. The clay was a mask of shame and anonymity.
Furthermore, Rashi explains that Rav Aha bar Rav Huna acted strictly in accordance with Rabbi Natan because Rabbi Natan "was a judge and descended to the depths of the law" (dayana hu ve-nachit le-umka de-dina). Rashi views Rabbi Natan's position not merely as a minority stringency, but as the conceptually superior legal theory.
3. Tosafot: The Synthesis of Dual Explanations
ושרקיה טינא - פי' טחו בטיט שלא יהנה מן העולם. א"נ יש לפרש שרקו כדי שלא יכירהו רב חסדא שהיה מתבייש על מה שלא קיים נדרו:
מאן חכים כו' - שלא היה רוצה להתיר עד שהשיאו וחל הנדר:
ה"נ בשאלה - דקסבר הלכה כרבי נתן:
Translation: “He smeared him with clay — meaning he smeared him with clay so that he would not benefit from the world. Alternatively, it can be explained that he smeared him so that Rav Hisda would not recognize him, as he was embarrassed about not having fulfilled his vow. Who is wise etc. — that he did not want to permit it until he married him off and the vow took effect. So too in inquiry — for he holds the halakha is like Rabbi Natan.”
Tosafot's Chiddush
Tosafot Tosafot on Nedarim 90a:1:1 acts as the classic dialectical bridge. They present both options:
- The Objective Halakhic Barrier: The clay functions as a non-clothing protective layer to avoid violating the vow of non-benefit from the world.
- The Subjective Psychological Mask: The clay was a disguise born of deep embarrassment (she-hayah mitbayeish) over his failure to maintain his spiritual resolve.
By framing these as two distinct paths, Tosafot forces us to ask: Is the primary challenge of hatarat nedarim the physical mechanics of the cheftza (the prohibited object/action), or the psychological state of the gavra (the person) standing in shame before the sage?
4. Shita Mekubetzet: The Semantic Shift and the Metaphysical Altar
ושרקיה בטינא. שטח פניו כדי שימצאהו פתח לנדרו דהא דאמר דתני הלכתא משמע הכי לשנות הלכה ומשמע לשנות פניו וכבר נשתנה שטח פניו בטיט ואתא לקמיה דרב חסדא כרי שיהא מתיר לו נדרו...
...אבל בשאלה דברי הכל אין חכם מתיר אלא אם כן חל עליו נדר דכתיב לא יחל דברו...
Translation: “He smeared him in clay — he smeared his face in order that he would find an opening [petach] for his vow. For that which was said, ‘he repeated the halakha’ [tani hilcheta], implies this: to change the halakha, and it also implies to change his face [leshannot panav], and his face was already changed by smearing it with clay, and he came before Rav Hisda so that he would permit his vow... But regarding inquiry, everyone agrees that a sage does not permit unless the vow has taken effect upon him, as it is written: ‘He shall not profane [yachel] his word’...”
Shita Mekubetzet's Chiddush
The Shita Mekubetzet Shita Mekubetzet on Nedarim 90a:1 offers a brilliant, almost poetic linguistic analysis.
He connects the phrase tani hilcheta (which usually means to teach or repeat the law) with the concept of shinuy (change/alteration). By smearing his face with clay, the disciple underwent a physical shinuy panim (change of face). This physical alteration mirrored the halakhic transformation (shinuy) that the Chacham was about to perform on his vow.
Additionally, the Shita Mekubetzet provides a deep homiletical reading of Rabbi Natan's derivation of chaferah (from Isaiah 24:23). He links it to the Rabbinic maxim that "he who vows is as if he built a high place (bamah)." The moon being "confounded" represents the dismantling of this self-made, illegitimate altar. Therefore, the Chacham cannot dismantle the "altar" of the vow until the altar has actually been erected (chal).
Friction
The Conceptual Clash: Retroactive Annulment (Akara) vs. Prior Realization (Chaloos)
The core conceptual tension of this sugya lies in a profound contradiction regarding the mechanism of she'eilah (sage's dissolution).
It is a well-established principle in Hilchot Nedarim that a Chacham’s dissolution operates via akara me-ikaro—retroactive uprooting Nedarim 21b. When a Chacham dissolves a vow, he does not merely terminate it from this point forward; rather, he uncovers that the vow was fundamentally flawed from its inception due to a petach (opening) or charata (regret). Conceptually, the vow is revealed to have never existed.
If so, we face a powerful kushya:
The Kushya
If the Chacham's power is to retroactively erase the vow from the moment of its utterance, why must we wait for the vow to take effect (lachul) before he can dissolve it?
If the vow is destined to be uprooted from its very root, the physical occurrence of the triggering condition should be irrelevant. The mental resolve—the ratzon that created the potential chaloos—is already fully present in the world. Why can the Chacham not uproot the ratzon now, preventing the chaloos from ever occurring?
We can contrast this with hafara (husband's nullification). A husband’s nullification is meizach—it cuts the vow from this point forward Nedarim 60a. Because hafara is a future-facing termination, it is logically coherent to argue that you cannot terminate something that has not yet begun. If there is no active chaloos, there is nothing to cut.
But for a Chacham, whose tool is retroactive uprooting (akara), this limitation seems completely illogical!

The Terutzim
To resolve this friction, we must look to the classic chakirot of the Acharonim, specifically the Brisker school and the Or Sameach.
Terutz A: The Ontological Status of the Cheftza (The Brisker Approach)
The Griz Soloveitchik Chiddushei HaGriz on Nedarim resolves this by distinguishing between the gavra (the person) and the cheftza (the object of prohibition).
The power of she'eilah is indeed akara (retroactive uprooting), but it is fundamentally a judicial act of dismantling a prohibition (hatarat issur). A Chacham does not merely engage in psychological therapy to alter a person's desires; he must act upon an existing halakhic entity—a cheftza shel issur (a prohibited object).
- Before the Chaloos: Although the person’s mental resolve (ratzon) exists, there is no actual issur resting on any object. The world remains completely permitted to him.
- The Halakhic Deficit: Because there is no active issur in the world, the Chacham has no judicial subject matter to operate upon. You cannot "permit" that which is already permitted.
- The Conclusion: Therefore, even though the mechanism is retroactive uprooting, the Chacham requires a concrete cheftza of issur to be present in the world before he can initiate the judicial process of hatarah.
Terutz B: The Or Sameach’s Distinction in the Nature of Retroactivity
The Or Sameach Rambam, Hilchot Nedarim 4:8 offers an alternative resolution based on the mechanics of retroactive legal fictions.
He argues that akara me-ikaro (retroactive uprooting) is not a magical time-travel mechanism that physically prevents the vow from ever being uttered. Rather, it is a legal determination that applies retroactively once the process is complete.
- The Mechanism: To initiate this legal determination, there must first be a binding legal reality to undo. If the vow has not yet taken effect, it is currently in a state of halakhic suspension. It is a "non-event" in terms of actionable prohibition.
- The Paradox of Annulling Nothing: If the Chacham were to dissolve it now, he would be dissolving a mere potentiality. Halakha does not apply its formal judicial tools to mere potentials.
- The Conclusion: The chaloos must occur to transition the vow from a subjective, potential thought into an objective, binding halakhic reality. Only once it is an objective reality can the Chacham deploy the legal fiction of retroactive uprooting to dismantle it.
Intertext
To see how this sugya reverberates across the broader landscape of Halakha, we must examine its codification in the Shulchan Aruch and its application in the classical responsa literature.
1. Halakhic Codification: Shulchan Aruch, Yoreh Deah 228:34
The Shulchan Aruch directly codifies the conclusion of our sugya, ruling in accordance with Rav Pappi’s final, refuted-then-reestablished assertion:
אין החכם מתיר הנדר עד שיחול. כיצד? אמר: "הריני נזיר כשיהיה לי בן", אף על פי שאינו יכול לחזור בו, אין חכם יכול להתיר לו עד שייולד הבן ויחול הנזירות.
Translation: "A sage does not dissolve a vow until it takes effect. How so? If one said: 'I am hereby a nazir when I have a son,' even though he cannot retract his words, a sage cannot dissolve it for him until the son is born and the naziriteship takes effect." — Shulchan Aruch, Yoreh Deah 228:34
The Commentators' Debate (Taz vs. Shach)
The Shach Yoreh Deah 228:44 and the Taz Yoreh Deah 228:26 grapple with the severe practical consequences of this ruling.
If a person makes a vow conditional on a future event, and he immediately regrets it, he is trapped. He cannot retract it because of the rule of amiran l'gavoah (one's word to the Sanctuary is binding), yet he cannot dissolve it because the condition has not yet been met.
The Shach notes that if the person wants to rid himself of the vow immediately, he must deliberately cause the condition to be fulfilled (if possible) solely to trigger the chaloos, allowing for immediate dissolution. This is the exact legal precedent established by Rav Aha bar Rav Huna!
2. Responsa Literature: The Chatam Sofer on Conditional Vows
A fascinating application of this sugya appears in the Responsa of the Chatam Sofer Chatam Sofer, Shailot U'Tshuvot, Yoreh Deah 220.
The Case
A young man vowed that he would not marry a specific woman unless he first completed a certain tractate of the Talmud. Before completing the tractate, he realized that this conditional vow was causing immense emotional distress to both families, and he wished to marry her immediately without completing the tractate. He went to a Chacham to dissolve the vow.
The Halakhic Dilemma
According to the Shulchan Aruch, the Chacham cannot dissolve the vow because it has not yet taken effect (since he has not yet married her without completing the tractate). But if he marries her without completing the tractate, he will instantly violate his vow! This is a classic catch-22.

[ Attempt Early Hatarah ] [ Marry Her Immediately ]

"No Hatarah before Chaloos!" ▼

(An Aveirah is committed)
The Chatam Sofer's Solution
The Chatam Sofer utilizes our sugya in Nedarim 90a to find a path forward. He argues that the restriction against dissolving a vow before it takes effect only applies if the chaloos is entirely dependent on an external, uncontrollable event (like the birth of a son).
However, if the trigger for the vow is entirely within the hands of the vower (such as entering a room or marrying a woman), the vow is considered to have a quasi-chaloos (chaloos talyah ve-omedet).
In such a case, the Chacham can perform hatarah even before the condition is formally met, because the vower's absolute control over the trigger makes the vow conceptually "at hand" (byado). This brilliant chiluk (distinction) limits the restriction of Nedarim 90a to uncontrollable future events, saving the young couple from an impossible halakhic deadlock.
Psak/Practice
How does this complex metaphysical debate land in contemporary halakhic practice?
1. The Mesorat Moda'ah (Erev Rosh Hashanah)
Every year on Erev Rosh Hashanah, Jews worldwide recite the Mesorat Moda'ah (declaration of intent regarding future vows) Kitzur Shulchan Aruch 128:16.
This practice is a direct response to the halakhic reality established in Nedarim 90a. Because we cannot easily dissolve vows before they take effect, and because we fear we might make a vow and violate it before we can reach a Chacham, we preemptively declare that any future vows we make are null and void.
This preemptive declaration acts as a vaccine, ensuring that the chaloos of any future accidental vow is structurally blocked at the moment of utterance.
2. Meta-Psak Heuristic: La'afokei Nafshei Mi-Pelugta
Our sugya also teaches a vital meta-psak heuristic modeled by Rav Aha bar Rav Huna: the value of constructing physical circumstances to resolve halakhic doubts.
When faced with a dispute between Rishonim where the lenient view is primary (the Rabbis) but the stringent view is conceptually powerful (Rabbi Natan), a great posek does not merely rule leniently. Rather, like Rav Aha bar Rav Huna with the clay, the posek should search for a creative, physical, or circumstantial solution that satisfies all opinions without placing the petitioner in spiritual jeopardy.
Takeaway
The debate over "smearing clay" in Nedarim 90a reveals that halakhic dissolution is not a mere psychological correction of intent, but a formal judicial dismantling of an active prohibition. To uproot a vow, one must first let it land.
