6084 - The Integrity of Halachic Walls and Public Boundaries

Class Summary & Analysis: Igros Kodesh, Vol. 16, Letter 6084

Recipient: Rabbi Yosef David Moskowitz (The Shatzer Rebbe), a prominent figure in the Agudas HaRabbonim. Context: The decade-long halachic debate regarding the establishment of a city-wide Eruv in Manhattan.

I. The Policy on Approbations (Haskamos)

The Rebbe declines the request for a formal Haskama for Rabbi Moskowitz's booklet, Kuntres Tikun Eruvin, citing several foundational reasons:

• The Chabad Tradition: The Rebbe explains it is not the custom (Minhag Beis HaRav) to provide formal approbations for books.

• Halachic Consistency: The Rebbe notes that his primary authority is his "grandfather," the Alter Rebbe. Since the Manhattan Eruv proposal relied on leniencies that do not align with the Alter Rebbe’s rulings in Shulchan Aruch HaRav, the Rebbe cannot lend his name to the publication.

II. The Halachic Technicalities of the Manhattan Eruv

The core of the disagreement centered on using the surrounding rivers as a Mechitzah (partition):

• Sea vs. River: While the recipient argued the water should be treated as a river (Nahar), the Rebbe notes that the Alter Rebbe (Siman 363) addresses a Sea (Yam). Because of tidal recession (low tide), the "wall" created by the embankment's slope disappears, rendering the partition invalid.

• The "Public Dump" Argument: The Rebbe rejects the interpretation that the Alter Rebbe's concern was only relevant when combined with a temporary trash dump. He clarifies that even a permanent public dump does not mitigate the fundamental issue of the receding water line.

III. The Danger of Publicity

While the Rebbe expresses personal joy that efforts were made to protect those already carrying on Shabbos, he issues a stern warning against publicizing the Eruv's completion:

• Target Audience: The Rebbe argues that non-religious Jews (who ignore the laws anyway) won't read the booklet. Conversely, religious Jews might use the "Hetter" (allowance) as an excuse to lower their standards.

• The "Rabbonim" Critique: In a sharp play on words, the Rebbe refers to certain modern leaders as Rabbonim (spelled with a Resh-Ayin, meaning "Bad Sons") who look to breach the walls of Torah rather than guard them. He warns that once a leniency is published, the damage to the community's spiritual standard is irreversible.

IV. Analytical Notes: The Nature of Rabbinic Mitzvos

In a lengthy postscript, the Rebbe engages in a deep scholarly "small talk of Torah" (Sichat Chullin shel Torah):

• Source of Authority: The Rebbe discusses whether the obligation to follow the Sages is a Positive Command (Aseh) based on "Ask your father" or a Prohibition (Lav) based on "Do not turn away" (Lo Tasur).

• The Rambam’s Nuance: He explains why the Rambam cites different verses in different contexts: in the context of Blessings (Hilchos Brachos), he cites the Positive Command, as one does not make a blessing over a Prohibition.

• The Number Seven: The Rebbe defends the tradition that there are exactly seven Rabbinic mitzvos (Netilas Yadayim, Eruvin, Brachos, Shabbos candles, Megillah, Chanukah, and Hallel), reconciling this with other codes (like the Smag) that count fewer. He links this number to the 620 letters of the Ten Commandments (Keter), where the 613 Torah commands are joined by 7 Rabbinic additions.

• Class Summary: Igros Kodesh Volume 16, Letter 6,084

  Background: This letter, dated Aleph d'Rosh Chodesh Adar 5718, is addressed to Rabbi Yosef David Moskowitz (the Shatzer Rebbe). Rabbi Moskowitz was a prominent member of the Agudas HaRabbonim and was spearheading an effort to establish a city-wide Eruv in Manhattan. He sent the Rebbe his published booklet, Kuntres Tikun Eruvin, seeking a formal approbation (Haskamah).

  1. The Rebbe’s Policy on Approbations

  The Rebbe declines to give a formal Haskamah, citing the Minhag Beis HaRav (tradition of the Chabad Rebbes) not to provide them. Furthermore, the Rebbe explains that as a "resident in the city of his Rav"—the Alter Rebbe—he must adhere strictly to the rulings of Shulchan Aruch HaRav. Since the proposed Manhattan Eruv relied on leniencies that contradict the Alter Rebbe's specific rulings, the Rebbe could not grant his approval.

  2. The Halachic Dispute: Sea Walls and Embankments

  The primary technical issue discussed is the use of the rivers surrounding Manhattan as a partition (Mechitzah).

  • The Alter Rebbe's Ruling: In Siman 363, the Alter Rebbe rules that the sea (or a tidal river) cannot serve as a wall because the water recedes (low tide), causing the necessary halachic incline/slope to disappear.

  • Refuting the Leniency: Rabbi Moskowitz argued that the Alter Rebbe's stringency only applied when combined with the removal of a temporary dump. The Rebbe refutes this, clarifying that the Alter Rebbe's ruling applies even to a public dump that is never expected to be removed.

  3. Warning Against Publication

  While the Rebbe expresses personal happiness that an Eruv was established to help protect those who might carry on Shabbos regardless, he issues a strict directive not to publicize it:

  • The Risk to the Religious: Those who do not care about Shabbos will not read the booklet. However, religious individuals might use the publication as a "Hetter" (allowance) to carry, leading to spiritual breaches.

  • The "Rabbonim": The Rebbe uses a sharp play on words, referring to certain modern leaders as Rabbonim (spelled with a Resh-Ayin, meaning "Bad Sons") who aim to "break through the walls of the religion" rather than protect them.

  4. Analytical Insights (The Postscript)

  The Rebbe concludes with a deep scholarly discussion on the nature of Rabbinic Mitzvos:

  • Authority: Is the obligation to follow the Sages a positive command ("Ask your father") or a prohibition ("Do not turn away")? The Rebbe analyzes the Rambam’s view, explaining that the prohibition is more stringent, but the positive aspect is highlighted when a blessing is required.

  • The Number Seven: The Rebbe defends the tradition that there are exactly 7 Rabbinic Mitzvos (Netilas Yadayim, Eruvin, Brachos, Candle Lighting, Megillah, Chanukah, and Hallel). He explains how these seven additions to the 613 Torah commands correspond to the 620 letters of the Ten Commandments (the crown/Keter).

  Conclusion: The Rebbe emphasizes that keeping even one Shabbos properly has the power to bring Moshiach immediately, reconciling the different views between the Jerusalem and Babylonian Talmuds based on the teachings of the Alter Rebbe in Likutei Torah.
