Mishneh Torah, Heave Offerings 4-6

Sugya Map

• Core Issue: The mechanism of shlichut (agency) in the separation of terumah and the limitations on who may act as a surrogate.
• Nafka Minot:
  • Does the agency rely on the halachic status of the agent (bnei brit) or their intellectual capacity?
  • Can an agent’s act be retroactively validated by the owner's later consent, and what constitutes "objection"?
  • Does shlichut for terumah require verbal appointment, or is it implied by the "temperament of the owner"?
• Primary Sources: Numbers 18:28, Kiddushin 41b, Bava Metzia 22a, Mishneh Torah, Heave Offerings 4:1-6.

Text Snapshot

The Rambam opens with the derivation of agency: "A person may appoint an agent to separate terumah... as Numbers 18:28 states: 'So shall you separate, also you.' [The wording implies] the inclusion of an agent."

Note the dikduk nuance: The Rambam relies on the word "also" (gam). In Mishneh Torah, Heave Offerings 4:1, the exclusion of the non-Jew is absolute: "Just as you are a member of the covenant, your agent must be a member of the covenant." The Loshon here is precise; agency is not merely a legal delegation of power, but an extension of the principal’s own mitzvah obligation. If the agent does not share the obligation, they cannot be the yad (hand) of the owner.

Readings

1. The Chiddush of the Kessef Mishneh

The Kessef Mishneh on Mishneh Torah, Heave Offerings 4:2 addresses the efficacy of separation by a non-permitted party (a cheresh, minor, or gentile). He argues that because the act lacks the da'at (intent) required for a mitzvah—which is a form of kiddush (sanctification)—the act is not merely "improper," it is objectively null. The Kessef Mishneh emphasizes that terumah is not just a tax; it is a change in the status of the produce. Without a "member of the covenant" (a ben brit) acting with proper intent, the ontological shift from tevel (untithed) to chullin (permitted) simply does not occur.

2. The Radbaz on Implicit Agency

The Radbaz addresses the fascinating case in Mishneh Torah, Heave Offerings 4:2 where one separates terumah without permission, and the owner later implies consent. The Radbaz posits a chiddush of "retroactive agency." He suggests that since there is a mitzvah involved—the owner is obligated to tithe—we assume that had the owner been present, they would have authorized the act. This creates a legal fiction of agency based on the assumption that a rational owner desires the completion of their religious obligation. Thus, if the owner does not explicitly object, the law fills the silence with consent.

Friction

The Strongest Kushya: A significant tension exists between the Rambam’s ruling in Mishneh Torah, Heave Offerings 4:11 regarding the nullification of agency and his stance in Hilchot Ishut. In Heave Offerings, the Rambam rules that an agent's separation remains effective even if the owner nullifies the agency after the appointment, provided the agent performs the act according to instructions. The Ra’avad famously attacks this: "This is a wonder! If he can appoint him through speech, why can he not nullify him through speech?"

The Terutz: The Radbaz and Kessef Mishneh offer two defenses. First, they distinguish between "active" agency and "passive" status. Once an agent is set on a path to perform a mitzvah, the act takes on a momentum of its own, and the principal’s speech lacks the power to "un-do" the incipient holiness (the kiddush of the terumah). Second, they suggest that the Rambam treats the appointment of a terumah agent as creating a specific, quasi-judicial status that cannot be unilaterally revoked once the agent has begun the process, unlike the appointment of a messenger for a secular contract.

Intertext

• Bava Metzia 22a: The source of the owner's "better ones" objection. The Gemara debates whether the owner's silence after the fact is mehilah (forgiveness) or haskamah (agreement). The Rambam sides with the latter, anchoring the effectiveness of the terumah in the owner's implied intent.
• Gittin 64a: The principle of "An agent can be assumed to have carried out his mission" (chazakah she-shaliach oseh shelihuto). The Rambam in Mishneh Torah, Heave Offerings 4:6 limits this: we only apply this chazakah to create stringency (prohibition), not leniency. This reveals a "Meta-Psak" heuristic: shlichut is a tool for fulfillment, not a loophole for avoidance.

Psak/Practice

In contemporary practice, this section serves as a fundamental check on the validity of terumah separation by third parties. The Rambam’s insistence that a non-Jew cannot be an agent remains the standard for kashrut certification—only a ben brit can separate terumah or ma’aser for a Jewish owner. Furthermore, the rule regarding "doubt" and the necessity of a second separation (where the first might have failed) serves as a baseline for le-chatchila (ideal) behavior. If an owner is uncertain about the agent's actions, the "stringent" approach—repeating the declaration—is the only way to ensure the produce is not tevel.

Takeaway

Shlichut in terumah is not merely legal representation; it is the delegation of a covenantal act, requiring both the agent’s shared identity as a ben brit and the owner’s underlying intent, which can sometimes be inferred even in the absence of explicit permission.
