Nedarim 56

Sugya Map

• Issue: Determining the precise scope and boundaries of a vow (neder) when the object of the vow is a general category (e.g., "house," "bed," "city"). The core tension lies between the literal interpretation of the term, common parlance (lashon benei adam), and specific halakhic or contextual definitions. This involves questions of klal u'prat (general and specific) and the principle of inclusion (bikhlal).
• Nafka Mina(s):
  • Vows on Dwellings:
    • Whether an upper story (aliyah) is included in a vow concerning a "house" (bayit).
    • Whether the ground floor is included in a vow concerning an "upper story."
    • Whether a "gallery" or "half-story" (kodkodin) is included in a "house" regarding nega'im (leprosy).
    • The definition of "house" for commercial transactions (e.g., selling "a house").
    • The precise boundary of a "house" for vows: from the doorstop inward, or does it include areas like under the lintel?
    • The boundary for nega'im in a house: "from the house" vs. "to the entrance of the house."
  • Vows on Furniture:
    • Whether a dargash (a type of couch/bed) is included in a vow concerning a "bed" (mittah).
    • Whether a mittah is included in a vow concerning a dargash.
    • Definitions of mittah and dargash based on construction (straps, loops).
    • Laws of tum'ah (ritual impurity) for beds and dargashim.
    • Laws of mourning (aveilut) regarding overturning beds and dargashim.
  • Vows on Locations:
    • Whether the Shabbat techum (2,000 cubits beyond city limits) is included in a vow concerning a "city."
    • Whether the ibur ha'ir (outskirts, 70.66 cubits adjacent to the city) is included in a vow concerning a "city."
    • The source for considering ibur ha'ir as part of the city (Joshua's entry into Jericho).
• Primary Sources:

Text Snapshot

The sugya on Nedarim 56a unfolds through three distinct Mishnayot, each presenting a machloket (dispute) between Rabbi Meir and the Rabbis regarding the scope of a vow, followed by Gemara analysis and elaboration.

Mishnah 1 (House / Upper Story)

מִשְׁנָה: הַנּוֹדֵר מִן הַבַּיִת – מוּתָּר בָּעֲלִיָּיה, דִּבְרֵי רַבִּי מֵאִיר. וַחֲכָמִים אוֹמְרִים: עֲלִיָּיה בִּכְלַל הַבַּיִת. הַנּוֹדֵר מִן הָעֲלִיָּיה – מוּתָּר בַּבַּיִת.

Mishnah: For one who vows that a house is forbidden to him, entry is permitted in the upper story of the house; this is the statement of Rabbi Meir. And the Rabbis say: An upper story is included in the house, and therefore, entry is prohibited there as well. However, for one who vows that an upper story is forbidden to him, entry is permitted in the house, as the ground floor is not included in the upper story. (Nedarim 56a)

• Dikduk/Leshon Nuance: The Mishnah uses "הבית" (the house) and "העלייה" (the upper story) with the definite article, implying specific, identifiable structures. The phrase "בִּכְלַל הַבַּיִת" (included in the house) is key to the Rabbis' position, indicating an inherent semantic inclusion. The final clause, "הַנּוֹדֵר מִן הָעֲלִיָּיה – מוּתָּר בַּבַּיִת," is stated unanimously, establishing a directional asymmetry in inclusion: an upper story is not a "house" in the same way a house might include an upper story.

Gemara on Mishnah 1 (Nega'im & Sales)

The Gemara immediately connects this machloket to the laws of nega'im:

גמרא: מַאן תְּנָא לְהָא דְּתַנְיָא: "בַּבַּיִת" – לְהָבִיא אֶת הַקּוֹדְקוֹדִין, "בַּבַּיִת" – לְהָבִיא אֶת הָעֲלִיָּיה? אָמַר רַב חִסְדָא: רַבִּי מֵאִיר הִיא. דְּאִי רַבָּנָן, הָא אָמְרִי רַבָּנָן עֲלִיָּיה בִּכְלַל הַבַּיִת הִיא!

Gemara: Who is the tanna who taught with regard to the halakhot of leprosy that in the verse “it appears to me as it were a plague in the house” (Leviticus 14:35), the term “in the house” comes to include the gallery [a half story], and “in the house” comes to include the upper story? Rav Ḥisda said: The tanna is Rabbi Meir, as, if the tanna were the Rabbis, didn’t the Rabbis say that a second story is included in the house? Why then do I need the verse containing the phrase “in the house” to include the second story? (Nedarim 56a)

• Dikduk/Leshon Nuance: The Gemara's question is based on a drasha from Vayikra 14:35. It uses "קודקודין" (gallery/half-story) and "עלייה" (upper story) as distinct but related architectural features. Rav Ḥisda's logic hinges on the idea that if aliyah is b'chelel bayit by common understanding (Rabbanan), a pasuk should be superfluous.

Abaye challenges Rav Ḥisda:

אֲבַיֵּי אָמַר: אֲפִילּוּ תֵּימָא רַבָּנָן, הַאי קְרָא צְרִיכִי לְהוּ. סָלְקָא דַּעְתָּךְ אָמֵינָא: הוֹאִיל וְכָתַב רַחֲמָנָא "בְּבֵית אֶרֶץ אֲחֻזַּתְכֶם" – מָה שֶׁמְּחוּבָּר לַקַּרְקַע הָוֵי בֵּית, עֲלִיָּיה דְּלָא מְחוּבָּר לַקַּרְקַע – לָאו בֵּית הִיא. קָא מַשְׁמַע לָן.

Abaye said: Even if you would say that the tanna is the Rabbis, they too require a verse to include the second story in this case, as it might enter your mind to say that since it is written: “In a house of the land of your possession” (Leviticus 14:34), only that which is attached to the ground has the status of a house but with regard to a second story, that is not attached to the ground. Even according to the Rabbis, the verse is necessary to prevent the conclusion that the legal status of a second story is not that of a house with regard to leprosy. (Nedarim 56a)

• Dikduk/Leshon Nuance: Abaye introduces "מְחוּבָּר לַקַּרְקַע" (attached to the ground) as a specific criterion for "house" in the context of nega'im, derived from "ארץ אחוזתכם." This highlights that a term's definition can vary by halakha.

The Gemara then shifts to a commercial law halakha:

מַאן דְּאָמַר לֵיהּ לְחַבְרֵיהּ: בַּיִת בְּבֵיתִי אֲנִי מוֹכֵר לְךָ, מַרְאֵהוּ עֲלִיָּיה. הָא לָא אָמַר לֵיהּ בַּיִת סְתָם – לָא מַרְאֵהוּ עֲלִיָּיה. לֵימָא רַבִּי מֵאִיר הִיא? אֲפִילּוּ תֵּימָא רַבָּנָן, מַאי עֲלִיָּיה? – עִילּוּיָא דְּבָתִּי.

In accordance with whose opinion is that which Rav Huna bar Ḥiyya said in the name of Ulla? If the seller says to the buyer: A house in my house I am selling to you, he may show the buyer that he purchased the second story [aliyya]. The Gemara infers: The reason is that the seller said to him: A house in my house I am selling to you. However, if he sold him a house, unspecified, he may not show him a second story. Let us say that this is the opinion of Rabbi Meir, who states that the second story is not included in the house. The Gemara rejects this claim: Even if you would say that it is in accordance with the opinion of the Rabbis, what is the meaning of the term aliyya in this context? It does not mean second story; it means the most outstanding of the houses. Rav Huna bar Ḥiyya said in the name of Ulla that when one says a house in my house, he must show him the most outstanding part of his house. However, if he sold him a house without specification, he may show him a second story. (Nedarim 56a)

• Dikduk/Leshon Nuance: The specific phrasing "בית בביתי" (a house in my house) is crucial, implying a selection within his existing property. The Gemara reinterprets "עלייה" not as an upper story but as "עילויא דבתי" (the best/most outstanding of houses) in this context, demonstrating how a word can have multiple meanings depending on the context and the speaker's intent.

Mishnah 2 (Bed / Dargash)

מִשְׁנָה: הַנּוֹדֵר מִן הַמִּטָּה – מוּתָּר בַּדַּרְגַּשׁ, דִּבְרֵי רַבִּי מֵאִיר. וַחֲכָמִים אוֹמְרִים: דַּרְגַּשׁ בִּכְלַל מִטָּה. הַנּוֹדֵר מִן הַדַּרְגַּשׁ – מוּתָּר בַּמִּטָּה.

Mishnah: For one who vows that a bed is forbidden to him, it is permitted to lie in a dargash, which is not commonly called a bed; this is the statement of Rabbi Meir. And the Rabbis say: A dargash is included in the category of a bed. Everyone agrees that for one who vows that a dargash is forbidden to him, it is permitted to lie in a bed. (Nedarim 56a)

• Dikduk/Leshon Nuance: Similar to the "house" case, the dispute is over inclusion ("בִּכְלַל מִטָּה"). The unanimous clause again demonstrates directional asymmetry. The ambiguity of dargash drives much of the Gemara's discussion.

Gemara on Mishnah 2 (Defining Dargash)

The Gemara explores several definitions of dargash, connecting it to mourning laws and tum'ah:

גמרא: מַאי דַּרְגַּשׁ? עוּלָּא אָמַר: מִטַּת מַזָּל. רַבָּנָן לְעוּלָּא: הַהוּא דִּתְנַן: כְּשֶׁמְּסַפְּקִין אֶת הַפַּרְנָסָה לַמֶּלֶךְ – כָּל הָעָם מְסוּבִּין עַל גַּבֵּי קַרְקַע, וְהוּא מֵיסֵב עַל גַּבֵּי דַּרְגַּשׁ. כוּלֵּיהּ שַׁתָּא לָא יָתֵיב עֲלֵיהּ, וְהַאי יוֹמָא יָתֵיב עֲלֵיהּ?!... אֶלָּא קַשְׁיָא הָא קַשְׁיָא: דְּתַנְיָא: דַּרְגַּשׁ – אֵינוֹ הוֹפְכוֹ, אֶלָּא זוֹקְפוֹ... רַבִּי יִרְמְיָה אָמַר: מִטָּה – קוֹשֵׁר רְצוּעוֹתֶיהָ עַל גַּבֵּיהּ, דַּרְגַּשׁ – קוֹשֵׁר רְצוּעוֹתֶיהָ בְּגוּפָהּ... כְּשֶׁבָּא רָבִין אָמַר: שָׁאַלְתִּי אֶחָד מִן הַסּוֹפְרִים, וְרַב תַּחְלִיפָא מַעַרְבָאָה שְׁמֵיהּ, דְּמִתְחַזֵּי לְשׁוּקָא דְּבוּרְסְקִי. אָמַר לִי: מַאי דַּרְגַּשׁ? מִטָּה שֶׁל עוֹר.

Gemara: What is a dargash? Ulla said: It is a bed of good fortune, placed in the house as a fortuitous omen, and not designated for sleeping. The Rabbis said to Ulla: That which we learned in a mishna: When the people serve the king the meal of comfort after he buries a relative, all the people recline on the ground and the king reclines on a dargash during the meal. According to your explanation, during the entire year he does not sit on the bed; on that day of the funeral he sits on it?!... Rather, this is difficult, as it is taught in a baraita with regard to the custom of overturning the beds in the house of a mourner: With regard to a dargash in his house, the mourner would not overturn it, but he merely stands it on its side... When Ravin came from Eretz Yisrael to Babylonia, he said: I asked one of the Sages about the meaning of dargash, and Rav Taḥalifa, from the West, was his name, who frequented the tanners’ market. And he said to me: What is a dargash? It is a leather bed. (Nedarim 56a)

• Dikduk/Leshon Nuance: The Gemara's process of elimination for defining dargash is striking. It first attempts a functional definition ("מיטת מזל" – bed of fortune), then a structural one (R' Yirmiya's initial idea of strap attachment), and finally relies on Rav Tachlifa's empirical definition ("מיטה של עור" – leather bed) from one familiar with the industry. The phrase "קשיא הא קשיא" signals a strong rejection of Ulla's definition.

Mishnah 3 (City / Techum / Outskirts)

מִשְׁנָה: הַנּוֹדֵר מִן הָעִיר – מוּתָּר לִיכָּנֵס לִתְחוּמָהּ, וְאָסוּר לִיכָּנֵס לְעִיבּוּרָהּ. וְהַנּוֹדֵר מִן הַבַּיִת – אָסוּר אֶלָּא מִן הָאַגָּף וְלִפְנִים.

Mishnah: For one who vows that the city is forbidden to him, it is permitted to enter the Shabbat boundary of that city, the two-thousand-cubit area surrounding the city, and it is prohibited to enter its outskirts, the seventy-cubit area adjacent to the city. However, for one who vows that a house is forbidden to him, it is prohibited to enter only from the doorstop and inward. (Nedarim 56a)

• Dikduk/Leshon Nuance: "תְּחוּמָהּ" (its boundary) and "עִיבּוּרָהּ" (its outskirts) are technical halakhic terms with precise measurements. The distinction between them is crucial. "מִן הָאַגָּף וְלִפְנִים" (from the doorstop and inward) provides a precise spatial definition for a house's interior.

Gemara on Mishnah 3 (Defining City Outskirts & House Doorstop)

גמרא: מְנָא הָא מִלְּתָא דְּאָמְרִינַן: עִיבּוּרָהּ שֶׁל עִיר כָּעִיר דָּמֵי? אָמַר רַבִּי יוֹחָנָן: דְּאָמַר קְרָא: "וַיְהִי בִּהְיוֹת יְהוֹשֻׁעַ בִּירִיחוֹ" (יהושע ה, יג). מַאי "בִּירִיחוֹ"? אִילֵימָא בִּירִיחוֹ מַמָּשׁ, הָא כְּתִיב: "וִירִיחוֹ סֹגֶרֶת וּמְסֻגֶּרֶת" (יהושע ו, א)! אֶלָּא: לְמֵד מִכָּאן שֶׁהָיָה בְּעִיבּוּרָהּ.

Gemara: From where do we derive that the legal status of the outskirts of a city are like that of the city itself? Rabbi Yoḥanan said that it is as the verse states: “And it came to pass when Joshua was in Jericho, that he lifted up his eyes and looked” (Joshua 5:13). What is the meaning of “in Jericho”? If we say that it means in Jericho proper, isn’t it written: “And Jericho was completely shut” (Joshua 6:1)? Rather, learn from here that Joshua was in the outskirts of the city. And although he was in the outskirts, the verse states that he was in Jericho. (Nedarim 56a)

• Dikduk/Leshon Nuance: This drasha uses a contradiction between two verses to establish a halakhic definition. "בִּירִיחוֹ" (in Jericho) is interpreted broadly to include the ibur ha'ir due to the constraint of "סֹגֶרֶת וּמְסֻגֶּרֶת" (completely shut).

The Gemara then turns to the "doorstop" definition:

**מִן הָאַגָּף וְלִפְנִים – הָא מִן הָאַגָּף וּלְבָר – לָא. מֵיתִיבִי: "וְיָצָא הַכֹּהֵן מִן הַבַּיִת אֶל פֶּתַח הַבַּיִת וְהִסְגִּיר אֶת הַבַּיִת" (ויקרא יד, לח). יָכוֹל יֵלֵךְ לְבֵיתוֹ וְיַסְגִּיר? תַּלְמוּד לוֹמַר: "אֶל פֶּתַח הַבַּיִת". אִם "אֶל פֶּתַח הַבַּיִת", יָכוֹל יַעֲמוֹד תַּחַת הַמַּשְׁקוֹף וְיַסְגִּיר? תַּלְמוּד לוֹמַר: "וְיָצָא הַכֹּהֵן מִן הַבַּיִת" – עַד שֶׁיֵּצֵא מִכּוּלּוֹ שֶׁל בַּיִת. הָא כֵּיצַד? עוֹמֵד מִן הַצַּד וּמַסְגִּיר. וּמְנָא לַן דְּאִי אָזֵיל לְבֵיתֵיהּ וּמַסְגִּיר, אוֹ דְּקָאֵי תַּחַת הַמַּשְׁקוֹף וּמַסְגִּיר, הֲוֵי הִסְגֵּר? תַּלְמוּד לוֹמַר: "וְהִסְגִּיר אֶת הַבַּיִת" – מִכָּל מָקוֹם.

Gemara: However, from the doorstop outward, no, it is permitted to enter. Rav Mari raised an objection based on a verse written with regard to leprosy: “And the priest shall go out from the house to the entrance of the house, and he shall quarantine the house” (Leviticus 14:38). And the question was raised in the halakhic midrash: One might have thought that the priest may go to his house and quarantine the leprous house that he examined from there. Therefore, the verse states: “To the entrance of the house” (Leviticus 14:38). If he may go only to the entrance of the house, one might have thought that he may stand beneath the lintel and quarantine the house from there. Therefore, the verse states: “And the priest shall go out from the house,” indicating that he may not quarantine the house until he goes out from the entire house. How so? Ab initio, the priest stands outside, alongside the door jamb, and quarantines the house. And from where is it derived that if he went to his house and quarantined the house, or stood beneath the lintel and quarantined the house, that his quarantine is an effective quarantine after the fact? The verse states: “And he shall quarantine the house” (Leviticus 14:38), which means in any case. Apparently, the legal status of the area beneath the lintel is identical to the status inside the house, even if it is beyond the doorstop. The Gemara answers: It is different with regard to a leprous house, as it is written: “And the priest shall go out from the house,” indicating that he cannot quarantine the house until he goes out from the entire house. (Nedarim 56a)

• Dikduk/Leshon Nuance: The Gemara here applies a drasha from nega'im to challenge the Mishnah's definition of "house" for vows. The drasha distinguishes between l'chatchila (ideally) and b'dieved (after the fact) for the kohen's quarantine, suggesting the area under the lintel is considered "inside" the house for nega'im. The terutz (answer) is that nega'im has its own unique rules due to specific pesukim, again demonstrating context-dependent definitions.

Readings

The sugya on Nedarim 56a delves into the nuanced interpretation of vows, a subject heavily influenced by lashon benei adam (common parlance) and specific textual derivations. The Rishonim and Acharonim grapple with how these factors shape the scope of a neder.

Ran (Rabbeinu Nissim ben Reuven Gerondi)

The Ran's commentary provides a foundational understanding of the Mishnah's core disputes and definitions, serving as a critical lens through which to approach the sugya.

On Nedarim 56a:1:1 (House / Upper Story)

מתני' מן הבית מותר בעלייה - דלרבי מאיר עלייה ליתא בכלל בית ורבנן פליגי עליה דסבירא להו דעלייה בכלל בית מיהו מודו דהנודר מן העלייה מותר בבית:

Mishnah: From the house, one is permitted in the upper story - for Rabbi Meir, an upper story is not included in the category of a house. But the Rabbis dispute him, for they hold that an upper story is included in the category of a house. Nevertheless, they agree that one who vows from an upper story is permitted in the house. (Ran on Nedarim 56a:1:1)

• Chiddush: The Ran clearly frames the machloket between Rabbi Meir and the Rabbis as a dispute about semantic inclusion (bikhlal). For Rabbi Meir, "בית" (house) specifically refers to the ground floor, and "עלייה" (upper story) is a distinct entity. The Rabbis, however, view "בית" as a broader category that naturally encompasses an aliyah. This reflects differing approaches to lashon benei adam: R' Meir takes a more restrictive, precise interpretation, while the Rabbis adopt a more expansive, common usage.
• Crucially, the Ran emphasizes the unanimous agreement that "הנודר מן העלייה מותר בבית" (one who vows from an upper story is permitted in the house). This establishes a critical asymmetry. Regardless of whether an aliyah is bikhlal bayit, a bayit is never bikhlal aliyah. This implies a hierarchical or directional relationship: the more general term might include the specific, but the specific rarely includes the general. This principle guides the interpretation of many vows.

On Nedarim 56a:1:3 (City / Techum)

מותר ליכנס לתחומה - תוך אלפים אמה הסמוכים לעיר:

Permitted to enter its techum - within two thousand cubits adjacent to the city. (Ran on Nedarim 56a:1:3)

• Chiddush: The Ran provides the standard definition of techum Shabbat (Shabbat boundary) as the 2,000 cubits surrounding a city. The Mishnah's ruling that one is permitted to enter the techum when vowing from the city means that techum is not considered bikhlal ha'ir (part of the city) in terms of common parlance for vows. This contrasts sharply with the ibur ha'ir (outskirts).

On Nedarim 56a:1:4 (City / Ibur Ha'ir)

לעיבורה - תוך שבעים אמה ושיריים סמוך לעיר:

To its ibur - within seventy and a fraction cubits adjacent to the city. (Ran on Nedarim 56a:1:4)

• Chiddush: The Ran defines ibur ha'ir (city outskirts) as "שבעים אמה ושיריים" (70 and 2/3 cubits), which is the standard halakhic measure. The Mishnah rules that one is prohibited from entering the ibur ha'ir when vowing from the city. This implies that for vows, ibur ha'ir is considered bikhlal ha'ir. The Gemara's drasha from Joshua in Jericho (Yehoshua 5:13) supports this, indicating that even in Tanakh, "in Jericho" could refer to its immediate vicinity, not just the walled city proper. This shows that lashon benei adam can be influenced by biblical narrative and drasha.

On Nedarim 56a:1:5 (House / Doorstop)

מן האגף ולפנים - מסתימת הדלת ולפנים אבל מה שעומד לחוץ כשהדלת נועלת מותר בו:

From the doorstop and inward - from where the door closes and inward. But that which stands outside when the door closes is permitted. (Ran on Nedarim 56a:1:5)

• Chiddush: The Ran clarifies the precise boundary for a "house" in the context of vows: "מן האגף ולפנים." He defines agaf as the point where the door seals, meaning the outer edge of the threshold. This strict, physical definition for vows contrasts with the more expansive interpretation seen in nega'im, where the area under the lintel might still be considered "inside." The Ran's explanation reinforces the idea that lashon benei adam in vows often seeks a clear, observable demarcation.

Rashi (Rabbi Shlomo Yitzchaki)

Rashi's concise explanations provide the immediate contextual meaning, often highlighting the fundamental point of disagreement or shared understanding.

On Nedarim 56a:1:1 (House / Upper Story)

מתני' מותר בעלייה - שאין עלייה בכלל בית:

Mishnah: Permitted in the upper story - for an upper story is not included in the category of a house. (Rashi on Nedarim 56a:1:1)

• Chiddush: Rashi, with his characteristic brevity, states the core chiddush of Rabbi Meir: "אין עלייה בכלל בית." This directly opposes the Rabbis' view. Rashi's formulation emphasizes the semantic distinction. For Rabbi Meir, the term "house" is not a generic term for "building" but specifically refers to the primary, ground-level structure. This precision in language is central to his approach to nedarim.

On Nedarim 56a:1:2 (Upper Story / House)

הנודר מן עלייה כו' - דברי הכל אין בית בכלל עלייה:

One who vows from an upper story, etc. - everyone agrees that a house is not included in the category of an upper story. (Rashi on Nedarim 56a:1:2)

• Chiddush: Rashi underscores the unanimous point of the Mishnah: "אין בית בכלל עלייה." This confirms the directional asymmetry observed by the Ran. While the scope of "בית" can be debated, the scope of "עלייה" is narrow and specific, never encompassing the more general "בית." This principle is crucial: when a specific term is used, its scope is generally limited to that specific item, even if that item is part of a larger category.

Rosh (Rabbeinu Asher ben Yechiel)

While the provided Rosh (Nedarim 8:3:1) is on a slightly earlier sugya (Nedarim 55b), it addresses a fundamental principle of nedarim: the role of kavana (intent) versus lashon (literal language), particularly when it concerns preventing a bitul mitzvah (negation of a mitzvah). This principle resonates deeply with our sugya on 56a, where the scope of words like "house" or "bed" is debated based on common usage and kavana.

On Nedarim 8:3:1 (Intent in Vows)

מתני' ר' יהודה אומר קונם יין שאני טועם עד א הפסח אינו אסור אלא עד לילי הפסח שלא נתכוין זה אלא עד שעה שדרך בני אדם לשתות יין אמר קונם בשר שאני טועם עד שיהא הצום אינו אסור אלא עד לילי הצום שלא נתכוין זה אלא עד שעה שדרך בני אדם לאכול בשר ר' יוסי בנו אומר קונם שום שאני טועם עד שתהא שבת אינו אסור אלא עד לילי שבת שלא נתכוין זה אלא עד שעה שדרך בני אדם לאכול שום. הרמב"ם ז"ל כתב דאין הלכה כר"י ובנו וחילק בין לא נתכוין דהכא ללא נתכוין זה אלא לשם אכילה ושתייה דסוף פירקין ובין לא נתכוין דלעיל (נדרים דף נה:) דטעון והזיע ובעיני נראה שאין לחלק דגבי לביתך שאני נכנס וטיפת צונן שאני שותה אנן סותרין דבריו מפני כוונתו והנדר בטל לגמרי כל שכן שנלך אחר כוונתו לזמן נדרו והכוונה זו בריאה וטובה שאינו רוצה להיות נמנע מן המצוה:

Mishnah: Rabbi Yehuda says: If one vows, "Konam wine that I taste until the eve of Pesach," it is forbidden only until the night of Pesach, for he intended only until the time when people usually drink wine. If he said, "Konam meat that I taste until the fast," it is forbidden only until the night of the fast, for he intended only until the time when people usually eat meat. Rabbi Yosei son of Rabbi Yehuda says: If one vows, "Konam garlic that I taste until Shabbat," it is forbidden only until the night of Shabbat, for he intended only until the time when people usually eat garlic. The Rambam z"l wrote that the halakha is not like Rabbi Yehuda and his son, and he distinguished between "he did not intend" here, and "he intended only for eating and drinking" at the end of the chapter, and between "he did not intend" above (Nedarim 55b) regarding "charged and sweated." But in my eyes, it seems there is no distinction, for regarding "into your house I shall enter" and "a drop of cold water I shall drink," we negate his words due to his intent, and the vow is entirely nullified. How much more so should we follow his intent for the duration of his vow, and this intent is sound and good, for he does not wish to be prevented from a mitzvah. (Rosh on Nedarim 8:3:1)

• Chiddush: The Rosh directly challenges the Rambam's restrictive approach to kavana in nedarim. The Rambam maintains that kavana can only override lashon in specific circumstances (e.g., nedarim that contradict an explicit mitzvah, or where the noder explicitly states his kavana was not for the neder to apply literally). The Rosh, however, argues for a broader application of kavana. He points to instances where the Gemara negates a neder entirely due to the noder's intent, even if not explicitly stated (e.g., if he vowed not to enter his friend's house, but intended his own house). If kavana can nullify a neder entirely, it certainly can modify its temporal scope.
• The Rosh's key argument is that when the underlying intent (kavana) is "sound and good" – particularly when it aims to prevent being "prevented from a mitzvah" (e.g., eating on Pesach, breaking a fast, enjoying Shabbat) – then kavana should take precedence over the literal lashon. This introduces a teleological element to neder interpretation.
• Relevance to Nedarim 56a: This Rosh is highly relevant because the sugya on 56a is fundamentally about defining the scope of a vow. While the examples there are spatial/object-based, the underlying principle of how lashon benei adam is interpreted and whether kavana can modify it, is shared. The debate between Rabbi Meir and the Rabbis, and the various Gemara discussions on dargash or ibur ha'ir, all touch on what the noder "really meant" or what common parlance implies. The Rosh's assertion that kavana, especially kavana to avoid bitul mitzvah, can shape the neder's boundaries, provides an Acharon-level meta-principle that informs how we might approach the semantic inclusions and exclusions on Nedarim 56a. Even if a neder on "house" or "bed" doesn't directly involve a mitzvah, the Rosh's chiddush pushes for a more intent-sensitive reading of lashon benei adam in general.

In summary, the Ran provides precise halakhic definitions and clarifies the structural arguments of the Mishnah. Rashi offers the essential, immediate understanding. The Rosh, from a related sugya, provides a crucial Acharon perspective on the weight of kavana in nedarim, advocating for a more expansive role for the noder's intent, especially when it aligns with mitzvah observance, which can be seen as an underlying heuristic for interpreting lashon benei adam more broadly.

Friction

The sugya presents several points of conceptual friction, where the Gemara grapples with conflicting definitions or logical inconsistencies. One of the strongest and most illustrative kushyot revolves around the definition of a dargash.

The Strongest Kushya: What is a Dargash?

The Gemara's journey to define dargash is a prime example of rigorous textual analysis and the challenge of pinning down a term's meaning. Ulla's initial definition faces significant resistance:

גמרא: מַאי דַּרְגַּשׁ? עוּלָּא אָמַר: מִטַּת מַזָּל. רַבָּנָן לְעוּלָּא: הַהוּא דִּתְנַן: כְּשֶׁמְּסַפְּקִין אֶת הַפַּרְנָסָה לַמֶּלֶךְ – כָּל הָעָם מְסוּבִּין עַל גַּבֵּי קַרְקַע, וְהוּא מֵיסֵב עַל גַּבֵּי דַּרְגַּשׁ. כוּלֵּיהּ שַׁתָּא לָא יָתֵיב עֲלֵיהּ, וְהַאי יוֹמָא יָתֵיב עֲלֵיהּ?!

Gemara: What is a dargash? Ulla said: It is a bed of good fortune, placed in the house as a fortuitous omen, and not designated for sleeping. The Rabbis said to Ulla: That which we learned in a mishna: When the people serve the king the meal of comfort after he buries a relative, all the people recline on the ground and the king reclines on a dargash during the meal. According to your explanation, during the entire year he does not sit on the bed; on that day of the funeral he sits on it?! (Nedarim 56a)

Ulla defines a dargash as a "מיטת מזל" (bed of fortune), implying it's a symbolic, non-functional piece of furniture. The Gemara's first challenge, from a Mishnah in Sanhedrin (19a), is that a king reclines on a dargash during a meal of comfort for mourners. If it's merely a "bed of fortune" and not for use, it's strange for the king to suddenly use it on this particular day. While Ravina offers a terutz (comparing it to meat and wine, which are also provided on this unique day), the Gemara is not fully satisfied.

The deeper and stronger kushya against Ulla's definition comes from a baraita concerning mourning practices:

אֶלָּא קַשְׁיָא הָא קַשְׁיָא: דְּתַנְיָא: דַּרְגַּשׁ – אֵינוֹ הוֹפְכוֹ, אֶלָּא זוֹקְפוֹ. וְאִי אָמְרַתְּ מִטַּת מַזָּל הוּא, מִי אִיכָּא קַרְבִיטִין?

Rather, if defining a dargash as a bed of fortune is difficult, this is difficult, as it is taught in a baraita that Rabban Shimon ben Gamliel says: A mourner need not overturn a dargash; rather, he loosens the loops [karvitin] that connect the straps that support the bedding to the bedframe, and it collapses on its own. And if a dargash is a bed of fortune, does it have loops [karvitin]? (Nedarim 56a)

This is the most potent kushya because it attacks the physical reality implied by Ulla's definition. If a dargash is merely a symbolic "bed of fortune," why would Rabban Shimon ben Gamliel describe a specific physical action for it – "loosening its karvitin (loops) and it collapses"? This description strongly suggests a functional, structurally complex piece of furniture, designed for actual use, whose parts can be manipulated. A "bed of fortune" would presumably be a solid, decorative item, not something with straps and loops that need loosening to collapse. This internal contradiction within the baraita and Ulla's definition is labeled "קשיא הא קשיא" ("this is difficult, truly difficult"), indicating its severity.

The Best Terutz: A Leather Bed with Loops

The Gemara, recognizing the strength of this kushya, seeks a more robust definition for dargash. The terutz arrives via an empirical report:

כְּשֶׁבָּא רָבִין אָמַר: שָׁאַלְתִּי אֶחָד מִן הַסּוֹפְרִים, וְרַב תַּחְלִיפָא מַעַרְבָאָה שְׁמֵיהּ, דְּמִתְחַזֵּי לְשׁוּקָא דְּבוּרְסְקִי. אָמַר לִי: מַאי דַּרְגַּשׁ? מִטָּה שֶׁל עוֹר.

When Ravin came from Eretz Yisrael to Babylonia, he said: I asked one of the Sages about the meaning of dargash, and Rav Taḥalifa, from the West, was his name, who frequented the tanners’ market. And he said to me: What is a dargash? It is a leather bed. (Nedarim 56a)

This terutz is effective because:

1. Empirical Authority: It comes from Rav Tachlifa, who "frequented the tanners' market" (shuka d'burski). This detail lends significant credibility to his definition, as tanners would be intimately familiar with leather goods, including leather beds. This is a classic example of the Gemara appealing to expert testimony from those involved in a specific craft or trade to clarify realia.
2. Resolves the Karvitin Kushya: A "leather bed" (mittah shel or) perfectly accounts for the "loops" (karvitin) mentioned by Rabban Shimon ben Gamliel. Leather beds, especially ancient ones, often had a wooden frame with a network of leather straps or thongs forming the sleeping surface. These straps would be secured with loops that could be tightened or loosened. When loosened, the tension would release, causing the bed to "collapse on its own," just as described. This definition offers a concrete, physical reality that fits all the descriptions.

The Gemara then further refines the distinction between a mittah (regular bed) and a dargash (leather bed), based on how their support straps are attached:

רַבִּי יִרְמְיָה אָמַר: מִטָּה – קוֹשֵׁר רְצוּעוֹתֶיהָ עַל גַּבֵּיהּ, דַּרְגַּשׁ – קוֹשֵׁר רְצוּעוֹתֶיהָ בְּגוּפָהּ. ... רַבִּי יִרְמְיָה חַזַר בֵּיהּ, אֶלָּא הָא וְהָא בְּגוּפָהּ. וּמַאי בֵּינַיְיהוּ? מִטָּה – מוּשָׁלוֹת וְנִשְׁמָטוֹת בְּנִקְבִין, דַּרְגַּשׁ – מוּשָׁלוֹת וְנִשְׁמָטוֹת בְּקַרְבִיטִין.

Rabbi Yirmeya said: In a bed, one fastens the supporting straps over the bedframe; in a dargash, one fastens the straps through holes in the bedframe itself. ... Rather, with regard to both this, a bed, and that, a dargash, one fastens the straps through holes in the bedframes themselves, and the difference between them is: In a bed, the straps are inserted and extracted through holes in the bedframe; in a dargash, the straps are inserted and extracted through loops attached to the bedframe, as Rabban Shimon ben Gamliel said that one loosens the loops and the bedding falls on its own. (Nedarim 56a)

This final distinction, made by Rabbi Yirmeya (after refining his own initial definition), solidifies the terutz. Both types of beds have straps passing through the frame, but the mittah uses simple holes, while the dargash uses karvitin (loops). This not only clarifies the physical difference but also directly incorporates Rabban Shimon ben Gamliel's description, thereby fully resolving the kushya. The dargash is distinct not just by material (leather) but by its specific construction mechanism involving loops.

This iterative process of question, provisional answer, refutation, new answer, and further refinement is characteristic of the Gemara's lomdus. It demonstrates a commitment to resolving textual discrepancies and establishing precise definitions, which is paramount when dealing with halakha derived from vows, where semantic boundaries are determinative.

Intertext

The sugya on Nedarim 56a is rich with intertextual references, demonstrating how halakha is woven from various strands of Torah, Prophets, and other Mishnaic texts. These cross-references are not mere citations but integral to the Gemara's dialectic, serving as sources for definitions, challenges to interpretations, and contextual clarifications.

1. Nega'im in Houses (Leviticus 14:34-38)

The laws of nega'im in houses, detailed in Vayikra 14, are a central intertextual pillar for the first Mishnah's discussion on the scope of "בית" (house).

תּוֹרָה: "כִּי תָבֹאוּ אֶל אֶרֶץ כְּנַעַן אֲשֶׁר אֲנִי נֹתֵן לָכֶם לַאֲחֻזָּה וְנָתַתִּי נֶגַע צָרַעַת בְּבֵית אֶרֶץ אֲחֻזַּתְכֶם" (ויקרא יד, לד). "וְהִסְגִּיר אֶת הַבַּיִת שִׁבְעַת יָמִים" (ויקרא יד, לח).

Torah: "When you come to the land of Canaan, which I give you for a possession, and I put a plague of leprosy in a house of the land of your possession" (Leviticus 14:34). "And he shall quarantine the house for seven days" (Leviticus 14:38).

• Relevance:
  • Scope of "House": The Gemara on Nedarim 56a¹ asks who holds that "בית" (house) in Vayikra 14:35 includes a "קודקודין" (gallery) and an "עלייה" (upper story). Rav Ḥisda attributes this to Rabbi Meir, but Abaye argues that even the Rabbis (who hold aliyah is bikhlal bayit for vows) would need a pasuk for nega'im. Why? Because of the phrase "בְּבֵית אֶרֶץ אֲחֻזַּתְכֶם" (in a house of the land of your possession) (Vayikra 14:34), which implies a house must be "מְחוּבָּר לַקַּרְקַע" (attached to the ground). An aliyah, not directly attached, would thus require a specific drasha to be included. This demonstrates that the definition of a term like "house" can be context-dependent; its scope for nega'im might be different from its scope for nedarim due to specific textual requirements.
  • Boundary of "House": Later in the sugya, when defining the boundary of a house for vows ("מן האגף ולפנים" – from the doorstop inward), the Gemara raises an objection from the drasha on Vayikra 14:38². This pasuk states: "וְיָצָא הַכֹּהֵן מִן הַבַּיִת אֶל פֶּתַח הַבַּיִת וְהִסְגִּיר אֶת הַבַּיִת." The drasha concludes that l'chatchila, the Kohen must stand outside "מִכּוּלּוֹ שֶׁל בַּיִת" (the entire house), including the area under the lintel. However, b'dieved, even quarantining from under the lintel is valid because "וְהִסְגִּיר אֶת הַבַּיִת" implies "מִכָּל מָקוֹם" (in any case). This implies that the area under the lintel is considered part of the house. The Gemara resolves this by stating: "שָׁאנֵי בַּיִת הַמְּנוּגָּע, דִּכְתִיב: 'וְיָצָא הַכֹּהֵן מִן הַבַּיִת'" (It is different with regard to a leprous house, as it is written: "And the priest shall go out from the house")³. This again highlights that specific pesukim related to nega'im can create unique definitions for a "house" that do not apply to general nedarim.

2. Joshua in Jericho (Joshua 5:13, 6:1)

The second Mishnah's discussion of a vow on a "city" and its ibur ha'ir (outskirts) directly references the Book of Joshua.

נביאים: "וַיְהִי בִּהְיוֹת יְהוֹשֻׁעַ בִּירִיחוֹ" (יהושע ה, יג). "וִירִיחוֹ סֹגֶרֶת וּמְסֻגֶּרֶת מִפְּנֵי בְּנֵי יִשְׂרָאֵל אֵין יוֹצֵא וְאֵין בָּא" (יהושע ו, א).

Prophets: "And it came to pass when Joshua was in Jericho" (Joshua 5:13). "Now Jericho was completely shut up because of the children of Israel; none went out and none came in" (Joshua 6:1).

• Relevance: The Gemara on Nedarim 56a⁴ uses these two verses to derive the halakha that "עִיבּוּרָהּ שֶׁל עִיר כָּעִיר דָּמֵי" (the outskirts of a city are like the city itself) for the purpose of vows. Rabbi Yoḥanan explains that if Joshua was truly in Jericho when it was "completely shut up," that would be a contradiction. Therefore, he must have been in the "outskirts" (ibur ha'ir), yet the Torah still refers to him as "in Jericho." This drasha demonstrates how a linguistic inclusion (calling the outskirts "Jericho") is derived from a contextual necessity to resolve a seeming biblical contradiction. This becomes the source for the halakha that one who vows from a "city" is forbidden to enter its ibur ha'ir.

3. Mishnah Kelim 16:1 (Tum'ah of Vessels)

The Gemara's lengthy discussion on the definition of dargash (a type of bed) references a Mishnah in Tractate Kelim concerning when wooden vessels become susceptible to tum'ah (ritual impurity).

מִשְׁנָה כֵּלִים טז:א: כְּלֵי עֵץ, מֵאֵימָתַי מְקַבְּלִין טוּמְאָה? ... הַמִּטָּה וְהָעֲרִיסָה, מִשֶּׁיְּשַׁפֵּן בְּעוֹר הַדָּג.

Mishnah Kelim 16:1: Wooden vessels, from when are they susceptible to ritual impurity? ... A bed and a crib, from when he smooths them with the skin of a fish.

• Relevance: The Gemara on Nedarim 56a⁵ cites this Mishnah to challenge Rabbi Yirmeya's initial definition of a mittah (bed): "מִטָּה – קוֹשֵׁר רְצוּעוֹתֶיהָ עַל גַּבֵּיהּ" (in a bed, one fastens the straps over the bedframe). The kushya is: if the straps are fastened over the bedframe, obscuring the wood, why would the Mishnah in Kelim say that a bed becomes susceptible to tum'ah only after being "smoothed with the skin of a fish" (a finishing process for the wood)? The smoothing implies the wood is visible and integral. This kushya forces Rabbi Yirmeya to revise his definition. The revised definition (straps inserted through holes in the frame, but for a dargash through loops) then accounts for the Kelim Mishnah (the wood frame is visible and smoothed) while also incorporating Rabban Shimon ben Gamliel's karvitin. This demonstrates how halakha requires consistency across different areas of Jewish law, and definitions must be robust enough to withstand challenges from other mishnayot.

These intertextual engagements underscore the holistic nature of halakha. Definitions are not isolated but are constantly tested and refined against the entire corpus of sacred texts, ensuring conceptual coherence and accuracy.

Psak/Practice

The theoretical discussions and disputes in Nedarim 56a regarding the scope of vows on "house," "bed," and "city" have direct implications for practical halakha. The Shulchan Aruch codifies these rulings, predominantly adopting the position of the Rabbis (חכמים) in their disputes with Rabbi Meir.

1. House and Upper Story

The Mishnah presents a machloket between Rabbi Meir, who permits entry into an upper story when one vows on a "house," and the Rabbis, who prohibit it because "עלייה בכלל הבית" (an upper story is included in the house).

• Psak: The Shulchan Aruch rules in accordance with the Rabbis:

  שׁוּלְחָן עָרוּךְ, יוֹרֶה דֵעָה רע"ח:א: הַנּוֹדֵר מִן הַבַּיִת, אָסוּר בַּעֲלִיָּה, כִּי הָעֲלִיָּה בִּכְלַל הַבַּיִת; וְהַנּוֹדֵר מִן הָעֲלִיָּה, מֻתָּר בַּבַּיִת.

  Shulchan Aruch, Yoreh De'ah 278:1: One who vows from a house, it is forbidden for him in the upper story, for the upper story is included in the house; and one who vows from the upper story, it is permitted for him in the house.¹

  The Rema adds a nuance, noting that this is the accepted halakha but if the noder explicitly states his intention to exclude the upper story, his neder would be interpreted accordingly, as intent can override the default lashon benei adam in certain situations. However, the default psak is bikhlal ha'bayit.

2. Bed and Dargash

Similarly, the Mishnah debates whether a dargash is included in a vow on a "bed." Rabbi Meir permits it, while the Rabbis prohibit it, holding that "דרגש בכלל מטה" (a dargash is included in a bed).

• Psak: The Shulchan Aruch again follows the Rabbis:

  שׁוּלְחָן עָרוּךְ, יוֹרֶה דֵעָה רע"ח:ב: הַנּוֹדֵר מִן הַמִּטָּה, אָסוּר בַּדַּרְגַּשׁ, כִּי הַדַּרְגַּשׁ בִּכְלַל הַמִּטָּה; וְהַנּוֹדֵר מִן הַדַּרְגַּשׁ, מֻתָּר בַּמִּטָּה.

  Shulchan Aruch, Yoreh De'ah 278:2: One who vows from a bed, it is forbidden for him in a dargash, for the dargash is included in the bed; and one who vows from a dargash, it is permitted for him in a bed.²

  The Shach (Siftei Kohen) on YD 278:2 clarifies that the Shulchan Aruch here refers to the final definition of dargash found in the Gemara (a leather bed with loops), and this is what is included in the general term "bed."

3. City, Techum, and Ibur Ha'ir

The Mishnah rules that one who vows from a "city" is permitted to enter its techum (2,000 cubits) but prohibited from entering its ibur ha'ir (outskirts, 70.66 cubits).

• Psak: The Shulchan Aruch also codifies this distinction:

  שׁוּלְחָן עָרוּךְ, יוֹרֶה דֵעָה רע"ח:ג: הַנּוֹדֵר מִן הָעִיר, מֻתָּר לִיכָּנֵס לִתְחוּמָהּ, וְאָסוּר לִיכָּנֵס לְעִיבּוּרָהּ.

  Shulchan Aruch, Yoreh De'ah 278:3: One who vows from a city, it is permitted for him to enter its techum, and it is forbidden for him to enter its ibur.³

  This psak directly reflects the Gemara's derivations from the verses regarding Joshua in Jericho and the distinction between techum (considered "outside" the city) and ibur (considered "like the city itself").

4. House and Doorstop

The Mishnah states that for one who vows from a "house," entry is prohibited "מן האגף ולפנים" (from the doorstop and inward).

• Psak: This is also codified:

  שׁוּלְחָן עָרוּךְ, יוֹרֶה דֵעָה רע"ח:ג: וְהַנּוֹדֵר מִן הַבַּיִת, אָסוּר אֶלָּא מִן הָאַגָּף וְלִפְנִים.

  Shulchan Aruch, Yoreh De'ah 278:3: And one who vows from a house, it is forbidden for him only from the doorstop and inward.⁴

  This establishes a clear, physical boundary for a vow on a house, based on the common understanding of what constitutes "inside" a house.

Meta-Psak Heuristics:

1. Default to Rabbis' View: In disputes between Rabbi Meir and the Rabbis in nedarim, the halakha generally follows the Rabbis. This often means adopting a broader, more inclusive interpretation of common terms, reflecting a stricter approach to vows (assuming greater scope of prohibition) or a prevailing understanding of lashon benei adam.
2. Directional Asymmetry: The principle of "the specific is not included in the general, but the general might include the specific" (e.g., a bayit is not bikhlal aliyah, but aliyah is bikhlal bayit) is consistently applied. When a noder uses a specific term (e.g., aliyah, dargash), the vow is limited to that item. When a general term is used (e.g., bayit, mittah), its scope is broader.
3. Context-Dependent Definitions: The sugya highlights that definitions of terms can change based on the specific halakhic context (e.g., "house" for nedarim vs. for nega'im). Pesukim and drashot can create unique parameters for a term in one halakha that do not apply in another. This requires careful consideration of the entire halakhic landscape.
4. Role of Lashon Benei Adam and Intent: While the psak often follows the Rabbis' more inclusive interpretation of common parlance, the Rema reminds us that explicit intent can still override these default understandings. This maintains a balance between standardized linguistic interpretation and the subjective will of the noder.

In sum, the sugya provides a clear framework for interpreting the scope of vows, with the Shulchan Aruch largely adopting the Rabbis' expansive view, while acknowledging the nuances of intent and context.

Takeaway

The sugya in Nedarim 56a profoundly illustrates that the semantic boundaries of language are fluid, shaped by a dynamic interplay of common parlance (lashon benei adam), specific scriptural exegesis (drashot), and the unique halakhic context, ensuring that vows are interpreted with rigorous precision. This rigorous analysis of linguistic inclusion and exclusion forms a cornerstone of halakhic reasoning, demonstrating that the "meaning" of a word is often a function of its legal application.
