Menachot 32

Sugya Map

• Issue: The halachic authority of an established custom (minhag) to dictate practice, even potentially overriding a prophet's instruction. Specifically, the minhag of writing parshiot setumot (closed passages) in a mezuza vs. petuhot (open passages).
• Nafka Mina(s): The binding power of minhag; the limits of prophetic authority in halacha; the meta-halachic principle of minhag as a source of din.
• Primary Sources: Menachot 32a; Eruvin 13b; Rambam, Hilchot Mamrim 1:2.

Text Snapshot

אמר רבה אמר רב כהנא אמר רב: אליהו זכור לטוב בא ואמר חולצין במנעל – שומעין לו. אין חולצין בסנדל – אין שומעין לו, שכבר נהגו העם בסנדל.

(Menachot 32a)

This passage, presented in two slightly variant forms, establishes a profound principle: an existing minhag (here, chalitza with a sandal) holds such weight that even Eliyahu HaNavi cannot overturn it. The crucial phrase is "שכבר נהגו העם בסנדל" – "for the people have already accustomed themselves to a sandal." This implies that widespread public practice, once entrenched, creates a binding reality.

Readings

Rambam, Hilchot Mamrim 1:2

The Rambam codifies this principle broadly: "ואפילו אם היה הנביא גדול מחכמי הדור... אם אמר להם לשנות דבר מדברי תורה, או מדברי קבלה, או מדברי סופרים, או ממנהג שנהגו בו רוב ישראל... אין שומעין לו." (Rambam, Hilchot Mamrim 1:2). Chiddush: Minhag is elevated to the same authoritative level as divrei Torah, divrei Kabbalah, and divrei Sofrim in terms of its immunity to prophetic alteration.

Rosh, Yevamot 12:2

The Rosh, in his commentary on a parallel sugya in Yevamot (12:2), discusses the strength of minhag, particularly when it has become widespread and deeply ingrained, as in the case of chalitza. He often emphasizes that minhag gains its power from the collective acceptance of Klal Yisrael, effectively becoming a din through communal consensus, especially when it doesn't directly contradict an explicit issur de'Oraita. Chiddush: Emphasizes that the minhag's binding power stems from its widespread adoption and acceptance by the Jewish people, serving as a strong indicator of an authentic tradition.

Friction

Kushya

How can minhag, a human-initiated practice, override even Eliyahu HaNavi, a prophet whose words would presumably reflect Divine will? Doesn't the dictum "לא בשמים היא" (Devarim 30:12, Bava Metzia 59b) limit halachic authority to the Sages, not to popular custom?

Terutz

The Gemara in Eruvin (13b) states that minhag is itself a form of din. The Rambam (Hilchot Mamrim 1:2), by equating minhag with divrei Torah in this context, suggests that an established minhag is not merely a practice, but a manifestation of accepted Kabbalah or a rabbinic enactment that has been universally adopted. To overturn such a custom would lead to confusion and undermine the stability of halacha. The prophet's role is not to innovate where a halacha (even one established by minhag) already exists, but to clarify or reinforce existing mitzvos.

Intertext

• Eruvin 13b: The exact same statement by Rav Kahana in the name of Rav appears there, serving as a foundational source for the authority of minhag.
• Rambam, Hilchot Mamrim 1:2: As cited above, the Rambam explicitly includes minhag among the categories of halacha that cannot be changed by a prophet. This is a direct codification of the principle found in our sugya.

Psak/Practice

This sugya is foundational for the principle of Minhag Yisrael Torah Hi (a custom of Israel is Torah). It teaches that minhagim, once widely established and accepted, possess significant halachic weight and cannot be easily dismissed or altered, even by great authorities. In the context of our sugya, it explains why the minhag of writing mezuzot with parshiot setumot is followed, despite an earlier Tannaic opinion supporting petuhot.

Takeaway

Minhag Yisrael is not merely societal convention but a powerful halachic force, a testament to the collective Kabbalah of the nation, ensuring continuity and stability in practice.
