Menachot 70

Sugya Map

• Primary Issue: The legal status of "additional growth" (tosefet) when original, already-tithed seeds are replanted. Does the status of the "main" (ikar) body persist, or does the new growth create a de novo obligation?
• Core Dilemma: If we assume the tosefet is obligated in ma’aser, does the ikar require a second round of tithing?
• Nafka Minot:
  • Seed Disintegration: Distinction between seeds that decompose (obligated) vs. those that persist (the subject of the dilemma).
  • Normal vs. Abnormal Sowing: Whether the method of cultivation impacts the halakhic unity of the crop.
  • Attached Produce: Whether teruma can take effect on produce while still attached to the ground (mechubar).
• Primary Sources: Menachot 70a; Bikkurim 2:4; Demai 5:10; Leviticus 23:14 (prohibition of Chadash).

Text: Menachot 70a

"אמדן דאמדן דאמדן... ועשרינהו, והדר שתלינהו ואוסיפו להו... מי אזלינן בתר עיקר, ופטר ליה לתוספת, או דלמא בתר תוספת אזלינן ומחייב ליה לעיקר?"

Nuance: The term amdin (אמדן) implies a formal estimation or assessment—a hachshara (preparation) for the status of tavel. The tension lies in the word tosefet (addition). Is the tosefet an extension of the original Guf (body), or a distinct Davar Chadash (new entity)? The Gemara’s reliance on whether the seed "disintegrates" (balu) suggests a physicalist approach to legal identity: if the ikar is gone, the tosefet is a new creation. If it persists, the legal status of the ikar potentially "colors" the tosefet.

Readings

1. Rabbeinu Gershom (Menachot 69b)

Rabbeinu Gershom offers a crucial chiddush regarding the mechanism of the obligation. He posits that the ikar and the tosefet are inextricably linked by the initial act of tithing the kri (the pile). For him, the question isn't merely biological; it is transactional. By including the kernels in the kri before replanting, the owner has effectively "enveloped" the potential growth into the legal framework of the ma’aser. His reading suggests that if the ikar still exists, the tosefet is not a "new" entity but an expansion of a pre-existing obligation. The chiddush here is that human intent (via the kri) can preemptively define the status of future biological growth.

2. The Steinsaltz Interpretation

Rabbi Steinsaltz frames the dilemma through the lens of hecher'a (determination). He highlights the distinction Rabba makes between seeds that disintegrate and those that do not. His reading suggests a legal ontology: if the seed vanishes, the "legal chain of custody" is broken, necessitating a new tithing. If the seed persists, we face a "mixed status" crop. The Steinsaltz insight is that the halakha here is not merely about agriculture, but about the "legal life" of an object. If the ikar remains, the tosefet is treated as an appendage of that which has already been sanctified (teruma).

Friction

The Strongest Kushya: The Gemara struggles with the concept of teruma attached to the ground (teruma b’mechubar). The Sages challenge Abaye: "If you say the status of teruma applies to attached grain, then we have found teruma attached to the ground—but we learned in a baraita that such a thing does not exist!"

The Terutz (Resolution): Abaye’s defense is two-fold:

1. The Penal Distinction: He argues that the baraita regarding "no teruma in mechubar" refers only to the punitive aspect (the death penalty or the 1/5 surcharge). If one eats attached teruma, the act is legally "empty" because it is an unnatural way of eating. It is not that the teruma status doesn't exist; it is that the transgression of eating it is nullified by the abnormal nature of the act.
2. The "Commonality" Test: The Gemara reinforces this by comparing it to the eggs found in a bird carcass. If a behavior is "common" (like reaching into a carcass), the act is valid even if it seems abnormal. If it is "uncommon" (eating straight from the ground like an animal), the halakha ignores the act. Therefore, the teruma exists, but the liability remains dormant until the produce is detached.

Intertext

• Bikkurim 2:4: The primary source for the assertion that there is no teruma in mechubar. The Gemara here effectively reinterprets this mishnaic axiom as a statement about penal liability rather than sanctification.
• Leviticus 11:37–38: The "seed that is sown" (zera zerua) logic. The Gemara uses this to distinguish between dry shells (which interpose and prevent the combination of foods) and moist shells (which are part of the food). This provides a hermeneutic parallel: the physical state of the item (wet/dry, attached/detached) determines its legal susceptibility to impurity or tithes.

Psak/Practice

The sugya lands on a meta-psak heuristic: Intent vs. Physicality. When determining if a new growth inherits the status of its predecessor, we look for the "legal continuity" of the object.

• Rule of Thumb: If the ikar (original seed) is physically destroyed (as in species where it decomposes), the tosefet is a new legal entity.
• Practice: In modern agricultural halakha, this creates a distinction between crops that grow from perennial roots versus annual seeds. If the root remains, the "legal identity" of the plant carries over, potentially requiring us to treat the tosefet as belonging to the same ma’aser cycle as the ikar.

Takeaway

Halakhic identity is not merely biological; it is a construct of human intent and physical continuity. When we plant, we aren't just farming—we are either extending a previous legal obligation or initiating a new one based on the disintegration of the source.
