Text Snapshot

The Rambam opens his discussion of agency with a fundamental principle regarding who can be an agent:

אַף עַל פִּי שֶׁכָּל יִשְׂרָאֵל עֲרֵבִים זֶה לָזֶה וְכֻלָּם כְּגּוּף אֶחָד, אֵין אָדָם עוֹשֶׂה שָׁלִיחַ אֶלָּא לְבֶן בְּרִית. לְפִיכָךְ, הַנָּכְרִי אֵינוֹ נַעֲשֶׂה שָׁלִיחַ לְיִשְׂרָאֵל לְשׁוּם דָּבָר שֶׁיֵּשׁ בּוֹ שְׁלִיחוּת כְּלָל. וְכֵן יִשְׂרָאֵל אֵינוֹ נַעֲשֶׂה שָׁלִיחַ לְנָכְרִי לְשׁוּם דָּבָר שֶׁיֵּשׁ בּוֹ שְׁלִיחוּת כְּלָל. שֶׁנֶּאֱמַר: "וְכֵן תָּרִימוּ גַּם אַתֶּם", מַה אַתֶּם בְּנֵי בְּרִית אַף שְׁלוּחֵיכֶם בְּנֵי בְּרִית. וְהוּא הַדִּין לְכָל הַתּוֹרָה כֻּלָּהּ. וְכֵן הוּא הַדִּין לְהֶפֶךְ: מַה מְשַׁלְּחֵיכֶם בְּנֵי בְּרִית אַף בְּכָל דִּבְרֵי הַתּוֹרָה כֻּלָּהּ הַמְשַׁלֵּחַ צָרִיךְ שֶׁיִּהְיֶה בֶּן בְּרִית. (Mishneh Torah, Agents and Partners 2:1)

• Dikduk/Leshon Nuance:
  • "אֵין אָדָם עוֹשֶׂה שָׁלִיחַ אֶלָּא לְבֶן בְּרִית": The phrasing "אדם" (a person) rather than "ישראל" (a Jew) is critical. It implies a universal principle that any principal must appoint a ben brit, and conversely, a shaliach must act for a ben brit.
  • "לְשׁוּם דָּבָר שֶׁיֵּשׁ בּוֹ שְׁלִיחוּת כְּלָל": This translates to "for any matter whatsoever that involves agency." The word "כְּלָל" (at all) emphasizes the absolute nature of the exclusion, suggesting it applies broadly, not just to mitzvos. This is a central point of contention.
  • The source "וְכֵן תָּרִימוּ גַּם אַתֶּם" (Bamidbar 18:28) refers to Terumat Ma'aser. Steinsaltz notes that the word "גם" (also) teaches that "not only can they separate it themselves, but their agent can also separate terumah for them" (Steinsaltz on Mishneh Torah, Agents and Partners 2:1:2, citing Pe'er HaMishnah, Terumot 1:1). The Gemara then derives the general principle from here.
  • "וְהוּא הַדִּין לְכָל הַתּוֹרָה כֻּלָּהּ": This extension is crucial. It universalizes the ben brit requirement beyond Terumot to "the entire Torah." The Rambam reiterates this for the converse as well: "מַה מְשַׁלְּחֵיכֶם בְּנֵי בְּרִית אַף בְּכָל דִּבְרֵי הַתּוֹרָה כֻּלָּהּ הַמְשַׁלֵּחַ צָרִיךְ שֶׁיִּהְיֶה בֶּן בְּרִית". This means both the principal and the agent must be Bnei Brit for any Torah matter. Steinsaltz highlights other applications in Hilchot Ishut 3:17 and Hilchot Terumot 4:1 (Steinsaltz on Mishneh Torah, Agents and Partners 2:1:4).

Later in the chapter, the Rambam addresses the Geonim's takanah on harsha'ah for loans:

אֲבָל מִי שֶׁהִלְוָה מָעוֹת לַחֲבֵרוֹ, אֵינוֹ יָכוֹל לִכְתֹּב שְׁטָר הַרְשָׁאָה עַל הַהַלְוָאָה, וַאֲפִלּוּ אִם הַהַלְוָאָה בִּשְׁטָר. מִפְּנֵי שֶׁהַהַלְוָאָה לְהוֹצָאָה נִתְּנָה, וְאֵין מָעוֹת הַמַּלְוֶה בָּעוֹלָם. וְאֵין אָדָם מַקְנֶה דָּבָר שֶׁאֵינוֹ בָּעוֹלָם. אֶלָּא אִם כֵּן הִקְנָה שְׁטָר הַחִיּוּב בְּמַעֲמַד שְׁלָשְׁתָּן, שֶׁהוּא דִּין מִדִּינֵי הַתּוֹרָה שֶׁאֵין טַעֲמוֹ נוֹדַע כְּמוֹ שֶׁבֵּאַרְנוּ, אוֹ שֶׁהִקְנָה לוֹ הַחִיּוּב בְּכִתְבֵי יָד בִּשְׁטָר וּנְתָנוֹ לוֹ, שֶׁבָּזֶה מַקְנֶה לוֹ שִׁעְבּוּד הַקַּרְקַע. (Mishneh Torah, Agents and Partners 3:11)

וְזֶה דַּעְתִּי מִן הַגְּמָרָא. אֲבָל הַגְּאוֹנִים תִּקְּנוּ שֶׁמּוֹסְרִין הַרְשָׁאָה אַף עַל הַהַלְוָאָה, כְּדֵי שֶׁלֹּא יִטֹּל אָדָם מָמוֹן חֲבֵרוֹ וְיֵלֵךְ לוֹ לִמְדִינַת הַיָּם. וְעוֹד תִּקְּנוּ, שֶׁאִם מָסַר לוֹ הַרְשָׁאָה לִגְבּוֹת מָמוֹן חֲבֵרוֹ שֶׁהוּא בְּיַד אֲחֵרִים, אוֹ לִגְבּוֹת הַלְוָאָה מִמֶּנּוּ, וְלֹא הָיָה לַמּוֹסֵר קַרְקַע, שֶׁיַּקְנֶה לוֹ אַרְבַּע אַמּוֹת מִנַּחֲלָתוֹ שֶׁבְּאֶרֶץ יִשְׂרָאֵל, וְיַקְנֶה לוֹ בָּהֶן הַמָּמוֹן לִגְבּוֹתוֹ בְּהַרְשָׁאָה זוֹ. וְדִבְרֵיהֶם אֵלּוּ נִרְאִין לִי קַלִּים מְאֹד וְאֵין בָּהֶם מַמָּשׁ. וּמִי יֹאמַר שֶׁיֵּשׁ לָזֶה חֵלֶק בְּאֶרֶץ יִשְׂרָאֵל? וַאֲפִלּוּ אִם הוּא רָאוּי לְחֵלֶק אֵינוֹ בְּיָדוֹ עַכְשָׁיו. וְהַגְּאוֹנִים שֶׁתִּקְּנוּ תַּקָּנָה זוֹ לֹא אָמְרוּ יִקֹּב הַדִּין אֶת הָהָר, אֶלָּא פֵּרְשׁוּ שֶׁלֹּא תֻּקְּנָה אֶלָּא לְהַרְחִיק אֶת הַבַּעַל דִּין, שֶׁאִם יִרְצֶה הַבַּעַל דִּין לְדּוּן וְלָתֵת הַמָּמוֹן עַל הַרְשָׁאָה זוֹ הֲרֵי הוּא פָּטוּר. (Mishneh Torah, Agents and Partners 3:12)

• Dikduk/Leshon Nuance:
  • "מִפְּנֵי שֶׁהַהַלְוָאָה לְהוֹצָאָה נִתְּנָה, וְאֵין מָעוֹת הַמַּלְוֶה בָּעוֹלָם. וְאֵין אָדָם מַקְנֶה דָּבָר שֶׁאֵינוֹ בָּעוֹלָם": This is the core halachic principle: a loan is given for consumption, so the specific money is gone. One cannot transfer something non-existent (davar she'eino ba-olam). This is a foundational concept in kinyanim.
  • "אֶלָּא אִם כֵּן הִקְנָה שְׁטָר הַחִיּוּב בְּמַעֲמַד שְׁלָשְׁתָּן... אוֹ שֶׁהִקְנָה לוֹ הַחִיּוּב בְּכִתְבֵי יָד בִּשְׁטָר וּנְתָנוֹ לוֹ": Rambam offers two valid ways to transfer a debt: Ma'amad Shloshtan (a unique halacha whose reason is unknown, where the borrower agrees to pay a third party in the presence of the lender) or by transferring the shetar chiyuv (promissory note) itself, which conveys the shi'abud karka (lien on land).
  • "וְדִבְרֵיהֶם אֵלּוּ נִרְאִין לִי קַלִּים מְאֹד וְאֵין בָּהֶם מַמָּשׁ": This is a remarkably strong and rare rebuke from the Rambam against the Geonim. "Extremely flimsy and unsubstantial." This signals a deep conceptual disagreement.
  • "וְהַגְּאוֹנִים שֶׁתִּקְּנוּ תַּקָּנָה זוֹ לֹא אָמְרוּ יִקֹּב הַדִּין אֶת הָהָר, אֶלָּא פֵּרְשׁוּ שֶׁלֹּא תֻּקְּנָה אֶלָּא לְהַרְחִיק אֶת הַבַּעַל דִּין": Rambam interprets the Geonim's takanah as merely a deterrent (le-harhaka), not as a legally binding kinyan. He uses the idiom "יקוב הדין את ההר" (let the law pierce the mountain), implying that the Geonim would not override fundamental halachic principles (like ein adam makneh davar she'eino ba-olam) with a takanah.

Readings

The Scope of "Ben Brit" in Agency: Rambam's Rigorous Stance

The Rambam's opening statement in Hilchot Shluchin VeShutafin 2:1, declaring that "a non-Jew may never be appointed as an agent for any mission whatsoever" (לשום דבר שיש בו שליחות כלל), and that this applies "to the entire Torah" (לכל התורה כולה), presents a notably expansive interpretation of the Gemara's derivation from Bamidbar 18:28. This assertion has generated considerable discussion among Rishonim and Acharonim, particularly regarding its application to purely monetary matters.

Maggid Mishneh (R' Vidal of Tolosa, 14th Century)

The Maggid Mishneh on Hilchot Shluchin 2:1 grapples directly with the Rambam's sweeping language. He acknowledges the difficulty, noting that the Gemara in Avodah Zarah 26a and Bava Kamma 79b seems to indicate that a non-Jew can indeed be an agent for monetary transactions, provided no issur is involved. For example, a non-Jew may collect a debt for a Jew. If so, how can Rambam state "לשום דבר שיש בו שליחות כלל"?

The Maggid Mishneh offers a nuanced interpretation to reconcile the Rambam with the Talmudic sources. He explains that the Rambam's phrase "לשום דבר שיש בו שליחות כלל" must be understood in the context of shelihut as a halachic mechanism that confers legal status or effects a kinyan on behalf of the principal. In this sense, shelihut is primarily applicable to mitzvos or actions that directly depend on the principal's halachic status. For instance, a non-Jew cannot be an agent to perform kiddushin or gittin for a Jew, as these actions require the agent to be a ben brit to effect the halachic change. Similarly, a non-Jew cannot separate terumah for a Jew, as this is a mitzvah contingent on kedushat Yisrael.

However, for purely financial transactions, where the agent merely acts as a messenger or a conduit for the principal's will, and the legal effect of the transaction (e.g., kinyan) is ultimately attributed to the principal's prior instruction or subsequent ratification, a non-Jew can serve. The Maggid Mishneh concludes that the Rambam's intent is to exclude a non-Jew from shelihut for davar mitzvah or for any action where the agent must possess the halachic capacity of a ben brit to effect the transaction. Where the agent's role is merely executive, facilitating a kinyan that would otherwise be valid, a nochri is permissible. This aligns with the Gemara's understanding that "אין שליח לדבר עבירה" (there is no agency for a transgression) and "אין שליח אלא לזוכה" (agency is only for one who gains rights), implying that shelihut relates to the halachic validity of an act. The chiddush of the Maggid Mishneh is therefore to interpret Rambam's seemingly absolute prohibition as limited to halachically significant acts, not mere financial mediation.

Kesef Mishneh (R' Yosef Karo, 16th Century)

The Kesef Mishneh, commenting on the same halacha, largely concurs with the Maggid Mishneh's interpretation, bolstering it with further proofs and elaborations. He points to the Gemara in Gittin 23b, which states that a non-Jew cannot be an agent for get (divorce), because "אינו בן ברית" (he is not a ben brit). This Gemara is the primary source for the general principle of ben brit in shelihut. The Kesef Mishneh explains that the Gemara's context there is specifically about Gittin, which is a davar mitzvah (or at least a halachic act with profound halachic implications for issur ve-heter).

He clarifies that the Rambam's use of "לכל התורה כולה" means "for all matters of the Torah" that require agency to effect a halachic change, such as kiddushin, gittin, terumah, or korbanot. In these cases, the halachic capacity of the agent is paramount. However, when it comes to mundane commercial transactions, where the halachic capacity of the agent is not a prerequisite for the validity of the kinyan (which is ultimately performed by the principal or by virtue of the principal's money), a non-Jew can serve.

The Kesef Mishneh emphasizes that the core distinction lies between shelihut that creates a halachic reality (e.g., making a woman mekudeshet or megureshet) and shelihut that merely executes a financial transaction. For the latter, a non-Jew is a valid agent, as his actions are seen as merely facilitating the principal's will. The chiddush here is reinforcing the idea that the Rambam's strong language is not an absolute prohibition on any interaction, but rather a limitation on the halachic efficacy of shelihut when a ben brit status is intrinsically required for the act itself. This is critical for practical halacha, as it permits various forms of commercial activity involving non-Jewish intermediaries.

The Geonim's Harsha'ah Takanah: Rambam's Dissent

The Rambam's sharp critique of the Geonim's takanah regarding harsha'ah (power of attorney) for loans (MT Shluchin 3:11-12) is one of the most famous instances of his divergence from a widespread Geonic practice. The Geonim permitted granting harsha'ah for collecting loans, even without land, sometimes through the symbolic kinyan of 4 amot in Eretz Yisrael. Rambam vehemently rejects this, citing the fundamental principle of ein adam makneh davar she'eino ba-olam (one cannot transfer ownership of something non-existent).

Rosh (R' Asher ben Yechiel, 13th-14th Century)

The Rosh, in Bava Kamma Chapter 7, Siman 10 (and in his Psakim to Sanhedrin, Perek 3), strongly upholds the Geonim's takanah for harsha'ah on loans. Unlike Rambam, who limits the takanah to le-harhaka (intimidation), the Rosh views it as a fully binding legal instrument. He explains that the Geonim instituted this takanah "כדי שלא יטול אדם ממון חבירו וילך לו למדינת הים" (so that a person should not take his friend's money and travel overseas). This rationale—to prevent evasion of justice and facilitate debt collection—is a powerful justification for a rabbinic enactment.

The Rosh implicitly addresses the kushya of ein adam makneh davar she'eino ba-olam. He does not view harsha'ah as a kinyan in the conventional sense of transferring ownership of the debt itself. Rather, harsha'ah is a mechanism that transfers the right to litigate and collect the debt (koach ha-tevi'ah) to the agent. The agent becomes a representative with legal standing to pursue the claim in court. The Rosh (and many Rishonim) distinguish between transferring the chiyuv (the obligation of the borrower), which indeed cannot be done for a non-existent item, and transferring the reshut le-hitbo'a (the authority to sue). This authority is a pre-existing right of the principal, which can be transferred, even if the underlying asset (the loan money) is no longer in specie.

Furthermore, the Rosh would argue that even if there is a kinyan element, the Geonim's takanah effectively redefines what can be considered "existent" for the purpose of harsha'ah, or it establishes a new kinyan form for this specific purpose, authorized by the rabbinic power to enact takanot "למיגדר מילתא" (to create a fence around a matter) and "משום תקנת השוק" (for the benefit of commerce). The chiddush of the Rosh is his firm acceptance of the Geonic takanah as fully valid and binding, understanding harsha'ah as a transfer of litigative authority, not proprietary ownership, thereby circumventing Rambam's fundamental objection. He prioritizes the societal need for effective debt collection over a strict, literal application of kinyan principles to the debt itself.

Tur and Shulchan Aruch (R' Yaakov ben Asher, 13th-14th Century & R' Yosef Karo, 16th Century)

The Tur in Choshen Mishpat Siman 123 explicitly cites the Geonim's ruling regarding harsha'ah on loans, including the use of 4 amot in Eretz Yisrael for those without land. Crucially, the Tur presents this takanah as normative halacha, without the Rambam's strong reservations. He notes that although some authorities disagree, the practice is to follow the Geonim. This indicates that by the time of the Tur, the Geonic takanah had gained widespread acceptance.

The Shulchan Aruch (Choshen Mishpat 123:1), following the Tur, rules in accordance with the Geonim. He states: "כותבים הרשאה על הלואה אף על פי שהלואה להוצאה ניתנה ואין מעות המלוה בעולם... ונהגו לכתוב הרשאה על הלואה אף על פי שאין לו קרקע" (We write harsha'ah for a loan, even though a loan is given for consumption and the lender's money is not in existence... and the custom is to write harsha'ah for a loan even if he does not own land). This is a direct rejection of Rambam's view. The Shulchan Aruch acknowledges the theoretical kushya of ein adam makneh davar she'eino ba-olam but overrides it with the established takanah.

The Shulchan Aruch further details the mechanism of the harsha'ah. While traditionally a kinyan was required for harsha'ah (often on land), the Geonim made allowances for loans. The Shulchan Aruch records the takanah that even without a kinyan on land, an harsha'ah for a loan is valid due to the Geonic enactment. This demonstrates a clear psak that prioritizes the takanah for the sake of public order and effective justice over the strict kinyan requirements that troubled the Rambam. The chiddush of the Tur and Shulchan Aruch is their definitive psak establishing the Geonic takanah as binding halacha, thereby shaping the practical application of harsha'ah in Jewish law for centuries to come, largely diverging from the Rambam's stringent position.

Friction

The Geonim's 'Harsha'ah' on Loans: A Collision of Principle and Pragmatism

The most profound friction in the provided text arises from the Rambam's scathing dismissal of the Geonim's takanah allowing harsha'ah (power of attorney) for loans (Mishneh Torah, Agents and Partners 3:11-12). This is not a mere difference in opinion, but a clash between a fundamental halachic principle and a rabbinic enactment intended to address a pressing societal need.

The Strongest Kushya: Rambam's Unwavering Principle

The Rambam's kushya against the Geonim is rooted in the bedrock principle of kinyanim: "וְאֵין אָדָם מַקְנֶה דָּבָר שֶׁאֵינוֹ בָּעוֹלָם" (one cannot transfer ownership of something non-existent) (Mishneh Torah, Agents and Partners 3:11). When money is lent, it is given "לְהוֹצָאָה" (for consumption), meaning the specific coins or notes are no longer in existence as the lender's property. The borrower now owes a chiyuv, an obligation to return an equivalent amount, but not the original ain ha-cheftza (the specific item itself). Therefore, according to the Rambam, there is no "thing" (davar) to transfer ownership of via a standard kinyan to an agent.

The Geonim's proposed kinyan of 4 amot in Eretz Yisrael for those without land is likewise deemed "קַלִּים מְאֹד וְאֵין בָּהֶם מַמָּשׁ" (extremely flimsy and unsubstantial) by the Rambam. His objections are twofold:

1. Existence of Land: "וּמִי יֹאמַר שֶׁיֵּשׁ לָזֶה חֵלֶק בְּאֶרֶץ יִשְׂרָאֵל?" (Who is to say that this person has a portion in the Land of Israel?). This questions the factual basis of the kinyan.
2. Possession of Land: "וַאֲפִלּוּ אִם הוּא רָאוּי לְחֵלֶק אֵינוֹ בְּיָדוֹ עַכְשָׁיו" (And even if he is fit to receive a portion of the land, it is presently not in his possession). A kinyan on land requires the transferor to have actual possession or control over the land at the time of the kinyan.

From Rambam's perspective, the Geonim's takanah fundamentally undermines the sanctity and logic of halachic kinyan. How could they institute a takanah that seemingly "pierces the mountain" (יקוב הדין את ההר) of established halacha? This is the core kushya: does rabbinic authority extend to overturning fundamental halachic principles derived from the Talmud, even for a pressing societal need?

The Best Terutz (or two): Reinterpreting the Takanah and the Nature of Harsha'ah

The resolution lies in understanding the nature of harsha'ah and the scope of takanot Geonim.

1. Harsha'ah as Transfer of Litigative Authority, Not Ownership

Many Rishonim, including the Rosh (as discussed above), and later poskim like Netivot HaMishpat (CM 123:2) and Ketzot HaChoshen (CM 123:1), argue that harsha'ah is not primarily a kinyan that transfers ownership of the debt itself. Rather, it is a transfer of the power to litigate (koach ha-tevi'ah) from the principal to the agent. The debt remains legally owed to the principal, but the agent is empowered to stand in court as the principal's representative to demand payment.

This distinction is crucial:

• Rambam's View: Views harsha'ah as a quasi-transfer of the davar (the claim/debt) itself, thus running into ein adam makneh davar she'eino ba-olam.
• Other Rishonim's View: Views harsha'ah as a transfer of authority or agency to collect, which is not a davar in the sense of a physical object, but a legal right. This legal right does exist, and can be transferred (or delegated) without running afoul of the ein adam makneh principle. The agent becomes a shaliach for litigation, not a new owner of the debt. The kinyan used to establish harsha'ah (e.g., on land or a shetar) is merely a formal act to solidify this delegation of authority, not to transfer the debt itself.

2. The Scope and Authority of Takanot Geonim

The Geonim instituted their takanah "כדי שלא יטול אדם ממון חבירו וילך לו למדינת הים" (so that a person should not take his friend's money and travel overseas) (Mishneh Torah, Agents and Partners 3:12, quoting the Geonim). This is a classic justification for a takanah that addresses a societal ill and ensures justice. Rabbinic courts have the authority to enact takanot that may modify or even appear to contradict certain min ha-Torah laws, especially in monetary matters, for the sake of public order (takanat ha-shuk, mipnei tikkun ha-olam).

The Geonim, in this view, were not "piercing the mountain" by abrogating ein adam makneh davar she'eino ba-olam. Rather, they were creating a procedural mechanism for enforcing existing obligations more effectively. Even if the kinyan of 4 amot in Eretz Yisrael seems tenuous, it served as a symbolic act to formalize the harsha'ah within the established halachic framework, even if its actual proprietary effect was minimal. The Geonim prioritized the practical need for collecting debts and preventing fraud.

Rambam himself, in his terutz ("לֹא אָמְרוּ יִקֹּב הַדִּין אֶת הָהָר, אֶלָּא פֵּרְשׁוּ שֶׁלֹּא תֻּקְּנָה אֶלָּא לְהַרְחִיק אֶת הַבַּעַל דִּין"), indirectly validates the Geonim's intention, even if he disagrees with their method. He concedes it serves to "intimidate" the defendant, meaning it has a persuasive, albeit not binding, effect. Other Rishonim simply go further, arguing that the Geonim intended it to be fully binding, and their authority was sufficient to establish such a takanah for the koach ha-tevi'ah.

In essence, the Rambam takes a maximalist view of kinyan and a minimalist view of the Geonim's takanah, while other Rishonim take a more nuanced view of harsha'ah as a transfer of litigative right (not property) and a maximalist view of the Geonim's authority to legislate for societal needs. This intellectual tension highlights the delicate balance between rigorous adherence to principle and the pragmatic demands of a functioning legal system.

Intertext

1. Sheliach Le-Davar Aveira Ein Sheliach (Kiddushin 42a)

The Rambam's broad statement that a non-Jew cannot be an agent "לְשׁוּם דָּבָר שֶׁיֵּשׁ בּוֹ שְׁלִיחוּת כְּלָל" (for any mission whatsoever that involves agency) and "לְכָל הַתּוֹרָה כֻּלָּהּ" (for the entire Torah) (Mishneh Torah, Agents and Partners 2:1) immediately brings to mind the fundamental principle of "שליח לדבר עבירה אין שליח" (there is no agency for a transgression).

This principle, found in Kiddushin 42a, states that if one sends an agent to commit a sin, the agent is solely responsible, and the principal is exempt. The rationale is "דברי הרב ודברי התלמיד, דברי הרב קודמין" (the words of the Master and the words of the student; the words of the Master (God) precede). Since God forbade the action, the principal's instruction to transgress is null and void, and the agent's act cannot be attributed to the principal.

The connection to Rambam's ruling on non-Jewish agents is multi-faceted:

• Shared Underlying Concept: Both rules limit the scope of agency based on a higher authority. For sheliach le-davar aveira, it's Divine law. For a non-Jew, it's the halachic incapacity stemming from not being a ben brit for Torah matters. In both cases, the agent's act cannot effect the desired halachic outcome for the principal.
• Distinction in Scope: While "שליח לדבר עבירה" applies to any agent (Jew or non-Jew) for a davar aveira, Rambam's rule for a non-Jew applies to any davar mitzvah (or halachic act) for a ben brit. So, a non-Jew cannot be an agent for terumah (a mitzvah), even though it's not an aveira.
• Implications for Monetary Law: The Maggid Mishneh and Kesef Mishneh (as discussed in "Readings") reconcile Rambam's broad statement by limiting it to halachic acts requiring ben brit status. This aligns with the understanding that for purely monetary matters, where the agent is merely a conduit and the transaction's validity doesn't depend on the agent's halachic standing, a non-Jew can be an agent. This distinction is crucial, because "שליח לדבר עבירה" does apply to monetary aveirot (e.g., stealing), yet for non-sinful monetary transactions, a non-Jew can be an agent. Thus, the ben brit rule applies to the capacity to perform halachic acts, whereas sheliach le-davar aveira applies to the nature of the act itself.

2. Ma'amad Shloshtan (Bava Kamma 104b, Gittin 13b)

The Rambam, in his discussion of transferring debt, states that "אֶלָּא אִם כֵּן הִקְנָה שְׁטָר הַחִיּוּב בְּמַעֲמַד שְׁלָשְׁתָּן, שֶׁהוּא דִּין מִדִּינֵי הַתּוֹרָה שֶׁאֵין טַעֲמוֹ נוֹדַע כְּמוֹ שֶׁבֵּאַרְנוּ" (unless he transferred the obligation document through Ma'amad Shloshtan, which is a law from the laws of the Torah whose reason is not known, as we explained) (Mishneh Torah, Agents and Partners 3:11). This refers to a unique kinyan for transferring a monetary obligation.

• Mechanism: Ma'amad Shloshtan occurs when a lender instructs a borrower to pay a third party, and this instruction is made in the presence of all three parties (lender, borrower, and third party), and the borrower accepts the new obligation. The original debt to the lender is thereby extinguished, and a new debt is created directly from the borrower to the third party.
• Rambam's Emphasis: Rambam explicitly states that the reason for Ma'amad Shloshtan is unknown (שאין טעמו נודע). This signifies that it's a halacha le-Moshe mi-Sinai or a rabbinic enactment whose rationale is hidden, distinguishing it from kinyanim based on logical principles. It's an exception to the rule of ein adam makneh davar she'eino ba-olam.
• Contrast with Geonim's Takanah: This reference highlights the Rambam's consistency. He accepts Ma'amad Shloshtan as a valid, albeit supra-rational, mechanism for debt transfer because it is explicitly taught in the Talmud. However, he rejects the Geonim's takanah for harsha'ah on loans because it attempts to create a new, logically problematic kinyan (or a pseudo-kinyan) that is not supported by explicit Talmudic sources and violates fundamental kinyan principles. For Rambam, a rabbinic takanah cannot override such a deep-seated principle unless it is itself a halacha le-Moshe mi-Sinai or a universally accepted and understood rabbinic interpretation. The Geonim's takanah, in his view, was neither. The implication is that if the Geonim had phrased their takanah as a Ma'amad Shloshtan-like transfer of koach ha-tevi'ah rather than a kinyan on the loan, Rambam might have been more amenable.

Psak/Practice

The Rambam's positions on both the ben brit requirement for agency and the validity of harsha'ah for loans have significant ramifications for halachic practice, though his view is not universally accepted, especially concerning harsha'ah.

1. Ben Brit in Agency: Halachic Consistency

For halachic acts (davar mitzvah or issur ve-heter), the Rambam's stringent requirement that both agent and principal be Bnei Brit is widely accepted le-halacha. This means a non-Jew cannot be an agent for kiddushin, gittin, terumah, shechita, or any other act that intrinsically requires the halachic status of a Jew. This is codified in Shulchan Aruch Even HaEzer 35:8 for kiddushin, and Even HaEzer 134:1 for gittin.

However, for purely monetary transactions (dinei mammonot) that do not involve any issur, the poskim generally follow the interpretation of the Maggid Mishneh and Kesef Mishneh, allowing a non-Jew to act as an agent. The Shulchan Aruch Choshen Mishpat 182:1 states that a non-Jew can be a witness for a financial transaction that doesn't involve issur, which implicitly suggests their capacity in mammon. The critical distinction remains between acts requiring halachic status and mere facilitation of financial exchange. This allows for modern commercial interactions where non-Jewish brokers or intermediaries are used, provided no halachic prohibitions (e.g., ribbit, gezel) are transgressed.

2. Harsha'ah for Loans: Divergence in Practice

Here, the Rambam's view that harsha'ah for loans is "flimsy and unsubstantial" and merely for "intimidation" (Mishneh Torah, Agents and Partners 3:12) is largely not followed in practical halacha. The Shulchan Aruch Choshen Mishpat 123:1, following the Tur and the Rosh, explicitly rules that harsha'ah is valid for loans, even without land, due to the takanat ha-Geonim. This takanah became the accepted norm.

The meta-psak heuristic at play here is the weight given to takanot Geonim in the face of underlying Talmudic principles. While Rambam prioritized the Talmudic principle of ein adam makneh davar she'eino ba-olam, most poskim recognized the critical societal need to facilitate debt collection and prevent evasion. They understood the Geonim's takanah as a valid exercise of rabbinic authority to establish a new procedural mechanism for koach ha-tevi'ah (litigative authority), rather than a proprietary transfer, thereby circumventing Rambam's core objection. Thus, in contemporary Beit Din practice, a harsha'ah for collecting a loan is considered fully binding, reflecting the widespread acceptance of the Geonic takanah.

Takeaway

The Rambam, with characteristic rigor, delineates the bounds of agency based on foundational halachic principles like ben brit and ein adam makneh davar she'eino ba-olam. His notable friction with the Geonim on harsha'ah for loans highlights the eternal tension between strict adherence to theoretical halacha and the pragmatic demands of a functioning legal system, ultimately yielding a psak that prioritizes societal order.
