Mishneh Torah, Heave Offerings 4-6

Sugya Map

• Issue: The parameters of shlichut (agency) in terumah—specifically, who may act as an agent, the scope of implied consent, and the limits of cognitive terumah.
• Nafka Mina: Can a non-Jew or an incompetent individual effect terumah? Does the "agent" principle apply to unauthorized "good-faith" actors (the ariis or neighbor)?
• Primary Sources: Numbers 18:28, Kiddushin 41b, Rambam, Terumot 4:1-10.

Text Snapshot

• Numbers 18:28: "So shall you separate, also you."
• Rambam, Terumot 4:1: "The wording implies the inclusion of an agent."
• Leshon Nuance: The Rambam derives the halacha of shlichut from the word gam (also). As the Yitzchak Yeranen notes, the connection between "you" and the "agent" hinges on the status of bnei brit (covenantal members), excluding those not bound by the obligation (mitzvah).

Readings

• Rambam (Comm. to Mishnah, Terumot 1:1): The chiddush is that shlichut is not merely a legal convenience but a scriptural expansion of the mitzvah itself. If the mitzvah is "yours," the shaliach acts as an extension of your own hand.
• Radbaz (on 4:10): Addresses the "sharecropper" (ariis) dilemma. He argues that even an unauthorized actor can effect terumah if the owner's eventual silence implies "ratification," effectively retroactively appointing them as an agent.

Friction

• Kushya: If an agent is a legal proxy for the owner, why is the agent’s unauthorized separation sometimes valid (e.g., the ariis scenario in 4:10) but invalid for a gentile (4:1)?
• Terutz: The validity of the "unauthorized" act relies on a presumption of the owner's will (anashan). A gentile is excluded not because of his intent, but because he lacks the status of bnei brit—he cannot "stand in" for a covenantal obligation.

Intertext

• Kiddushin 41b: The locus classicus for why a gentile cannot be a shaliach—they are not "like you" in the context of covenantal law.
• Shulchan Aruch, Yoreh De'ah 331:34: The Rama disputes the Rambam regarding the "agent presumed to have acted" (hechezik shlichut), reflecting a broader debate on whether legal agency is an ontological fact or a procedural assumption.

Psak/Practice

The Rambam’s heuristic is da'ato shel adam (a person's intent). In modern practice, terumah via agency is largely theoretical due to our status as tme'im (ritually impure). However, the principle remains vital: agency requires the agent to share the principal's obligatory status.

Takeaway

Agency is not just a delegation of power; it is a spiritual projection. If the agent cannot fulfill the mitzvah for themselves, they cannot act as a vessel for yours.
