Nedarim 88

Sugya Map

• Core Issue: The hermeneutical status of mi’ut (exclusion) vs. ribui (inclusion) when multiple descriptors are present, specifically regarding the blind man (soma) and unintentional manslaughter Deuteronomy 19:5.
• Secondary Issue: The agency of a married woman (eshet ish) in acquisition (kinyan), specifically whether "the hand of a woman is like the hand of her husband" applies universally or is subject to specific transactional contexts.
• Nafka Mina:
  • Does a blind man incur galut (exile) for unintentional killing?
  • Can a wife act as an agent for her husband to acquire an eiruv if the husband has a right to her acquisitions?
• Primary Sources: Nedarim 88a, Deuteronomy 19:4-5, Eiruvin 73b, Kiddushin 23b.

Text Snapshot

The Gemara pivots on the phrase b’lo re’ot ("without seeing"):

• Rabbi Yehuda: Deuteronomy 19:5 ("goes into the forest") includes all capable of entering a forest. Thus, b’lo re’ot must be a mi’ut (exclusion) for the blind.
• Rabbi Meir: Deuteronomy 19:4 ("without knowledge") implies those capable of knowledge. B’lo re’ot is a ribui (inclusion), overriding the potential exclusion of the blind.
• Leshon Nuance: Rava’s intervention—ha’cha me’inyana d’kra (here, it follows the context of the verse)—signals that this is not a generic debate over svara (logic) but a linguistic parsing of specific Torah segments.

Readings

The Ran’s Synthesis

The Ran Nedarim 88a:1:1 addresses the kushya of why Rabbi Meir seems to hold contradictory positions on mikzat yedi’a (partial knowledge). In the Mishna, Rabbi Meir rules that "partial knowledge" is considered "full knowledge" regarding a husband's power to annul vows, yet here he seemingly ignores the blind man's lack of "full" sight. The Ran resolves this by arguing that in the case of the killer, the Torah’s linguistic structure (b’lo re’ot) acts as a specific gezeirat hakatuv (decree of the verse) meant to include the blind, regardless of whether he lacks "full" vision in the colloquial sense. He posits that the dispute is not about the abstract logic of "partial knowledge" but about how we weigh competing exclusions.

Rashi’s Precision

Rashi Nedarim 88a:1:2 focuses on the mechanics of the ribui. He explains that for Rabbi Meir, the term b’lo da’at (without knowledge) would have excluded the blind, but the subsequent b’lo re’ot acts as a ribui that pulls the blind back into the category of those liable for galut. Crucially, Rashi emphasizes that if b’lo re’ot were meant to exclude, it would be redundant because the blind man is already excluded by the nature of the act. Therefore, the presence of the phrase must function as a ribui. This aligns with the meta-rule that ein mi’ut achar mi’ut ela l’rabot (a second exclusion functions as an inclusion).

Friction

The Strongest Kushya

The most potent kushya arises from the inconsistency of Rabbi Meir: If he holds in the Mishna that "the hand of a woman is like the hand of her husband" (yada d’isha k’yada d’ba’alah), why does he allow a wife to acquire eiruv food on behalf of others in Eiruvin 73b? If her acquisitions belong to her husband, the eiruv has never left the husband's possession, rendering the ritual ineffective.

The Terutz

Rava provides the terutz in our text: Kivan d’ai’ta l’aknu’ei (since her aim is to acquire for others, not for herself), she operates in a different legal capacity. The husband’s kinyan on her acquisitions applies to her personal wealth, but when she acts as a vehicle for the eiruv—a communal legal construct—the law recognizes her capacity to "transfer" possession. Rav Ashi refines this, suggesting that the Mishnaic scenario assumes a woman who already possesses independent property—a hazarah (renunciation) by the husband—thereby breaking the automatic link between her hand and his.

Intertext

• Kiddushin 23b: This is the foundational text for the yada d’isha principle. The Gemara there establishes that a kanyan (acquisition) made by a slave is the master’s, and by extension, a wife’s kinyan is the husband’s. Our sugya in Nedarim 88a acts as a "stress test" for this rule: how far can we push the kinyan of a dependent before the law recognizes an independent agency?
• Numbers 30:10: The Gemara invokes this to discuss the nashim (women) whose vows stand. The transition from the laws of the killer to the laws of vows is not merely formal; it explores the boundary of "legal personhood." In both cases, the Torah defines the subject's capacity—the killer by his physical ability to enter a forest, the woman by her ability to bind her soul.

Psak/Practice

In modern halacha, the principle of yada d’isha k’yada d’ba’alah is largely viewed through the lens of minhag (custom) and t’nai (stipulation). The Shulchan Aruch Choshen Mishpat 249:3 generally maintains that whatever a wife acquires belongs to her husband, unless it is explicitly given as a gift al mnat she’ein l’ba’alah reshut bah (on condition that the husband has no rights to it). The psak here is that agency is not an immutable ontological state but a function of the t’nai attached to the transaction.

Takeaway

The law is not a rigid grid but a living dialogue between text and intent; whether a blind man kills or a wife acquires, the halacha parses the "context of the verse" to determine if the actor is a vessel for the law or a subject of it.
