Mishneh Torah, Tithes 7-9

Sugya Map

• Core Issue: The application of Bereirah (retroactive designation) within the laws of Terumot and Ma'aserot.
• Primary Conflict: Rambam’s rejection of Bereirah in Devarim She-bi-Reshut ha-Torah (Scriptural obligations) versus its acceptance in Devarim She-bi-Reshut ha-Rabbanan (Rabbinic obligations).
• Nafka Minot:
  • Drinking wine from a vessel before the tithe is physically removed.
  • Determining the validity of "stipulations" made before the Sabbath for produce that remains Tevel.
  • The status of Demai (doubtfully tithed produce) as a laboratory for Rabbinic leniency.
• Primary Sources: Mishneh Torah, Hilchot Ma'aserot 7-9; Beitzah 37b; Gittin 30a; Demai 7:1-8.

Text Snapshot

Rambam, Hilchot Ma'aserot 7:1: "If he says: 'The two lugim that I will separate are terumah; the ten are the first tithe, and the nine are the second tithe,' he should not begin drinking... We do not say that the wine he left over at the end is retroactively considered as if it was set aside in the beginning."

• Leshon Ha-Rambam: The phrase Ein Omrim (we do not say) serves as the definitive negation of the Bereirah mechanism. Note the dikduk of Le-Ma'aseh: the prohibition is not merely against the act of drinking, but against the conceptual framework that would attempt to validate the drinking via a retroactive mental construct.

Readings

Reading 1: The Ohr Sameach (R. Meir Simcha of Dvinsk)

The Ohr Sameach on Ma'aserot 7:1 focuses on Rambam’s insistence that in matters of Scriptural law, a mental designation is insufficient to permit consumption. He highlights the distinction between Bereirah (retroactive clarification) and Tnai (stipulation). In Bereirah, the object is intrinsically defined by the future act. In Tnai, we are establishing a condition for the status of the food. The Ohr Sameach argues that the Rambam’s stringency is not merely a rejection of Bereirah, but a fundamental limitation on the power of speech to alter the status of Tevel in the absence of a physical act.

Reading 2: The Ra'avad (R. Avraham ben David)

The Ra'avad frequently challenges the Rambam’s categorical rejection of Bereirah. In the context of Demai (Chapter 9), where the status is purely Rabbinic, the Ra'avad is far more permissive. His chiddush lies in the hierarchy of legal certainty: he posits that the Sages, in creating the category of Demai, intended for the Tikkun (fix) to be as fluid as possible. Where the Rambam sees a strict, logical requirement for physical separation to avoid Meduma (mixed status), the Ra'avad sees the Rabbinic Takkanah as a flexible tool designed to allow the common person to function within the system without undue hardship.

Friction

The Kushya: If Bereirah is a valid legal tool in the eyes of many Tannaim (e.g., Mishnah Beitzah 3:5), why does Rambam elevate its rejection to a cornerstone of Ma'aserot? Specifically, if the owner knows he will eventually separate the tithe, his intent is functionally present. Why does the lack of a physical act render the Tevel forbidden?

The Terutz: The Kessef Mishneh explains that the prohibition of Tevel is an ontological status—the produce is "bound" (as the root t-v-l implies). This bond is not broken by the owner's intention, but by the performance of the Mitzvah. To allow Bereirah would be to suggest that the Mitzvah is a matter of definitional bookkeeping rather than act-based rectification. Rambam maintains that for the Torah's obligations, the "bond" remains until the specific physical portion is separated.

Intertext

• Parallel: The logic mirrors the prohibition against slaughtering on the Sabbath Shabbat 73b, where the act of "finishing" (Gomer) or "fixing" (Tikun) is the violation. Just as one cannot create a "fixed" object on the Sabbath, one cannot create "ordinary" food from Tevel via mere mental stipulation when the Torah requires an action.
• Responsa: The Radbaz (on Ma'aserot 7:1) connects this to the broader principle of Sfeika de-Rabbanan Le-Kula (doubts in Rabbinic law are resolved leniently). He notes that while we are stringent in Scriptural law (no Bereirah), the Sabbath context creates a unique exigency where the Sages permitted stipulation as a "pre-emptive" Bereirah to avoid the prohibition of Maktir (preparing on Sabbath).

Psak/Practice

The meta-psak heuristic here is the "Reality of Separation." In contemporary practice—specifically regarding Demai or purchasing from sources with questionable Ma'aser status—we do not rely on Bereirah. One does not simply say, "I am eating this, and the tithe will be defined later." We utilize the specific Nusach (formula) provided by the Shulchan Aruch (based on Rambam) to physically or conceptually isolate the portion before the act of consumption. Even on Rosh Chodesh Tamuz, as we transition into the summer harvest cycles, the principle holds: Ma'aser is not an idea; it is a physical commitment.

Takeaway

The prohibition of Tevel is a physical reality that cannot be dissolved by a mental contract; true spiritual clarity requires the act of separation, not merely the intention to perform it.
