Mishneh Torah, Marriage 5-7

Hook

Why would the validity of a marriage hinge on whether a piece of bread is considered "money"? In the eyes of Jewish law, kiddushin (betrothal) is not merely a social contract; it is a transactional event where the man must transfer something of tangible value to the woman. If the law deems an object "worthless"—not because it lacks market price, but because it is forbidden to derive benefit from—the entire foundation of the marriage collapses.

Context

The Mishneh Torah, written by Maimonides (Rambam) in the 12th century, serves as the definitive codification of Jewish law. This specific passage (Marriage 5:1) draws heavily from the Talmudic tractate Kiddushin (56b–58a). Historically, this ruling highlights the Rabbinic tension between "objective value" (the market price) and "legal status" (the permitted use). The Rambam’s insistence that illicit objects have "no value" reflects a rigorous legal philosophy: a prohibited item is essentially a legal void, incapable of anchoring a sacred bond.

Text Snapshot

"When a man consecrates a woman with an object from which it is forbidden to derive benefit - e.g., a mixture of milk and meat, chametz on Pesach, or other similar objects... she is not consecrated. Since it is forbidden to derive benefit from the article, according to the Torah, it has no value whatsoever. For a woman to be consecrated, she must receive an article worth a p'rutah." Mishneh Torah, Marriage 5:1

Insight 1: The Ontology of "Value"

The Rambam’s assertion that a forbidden object has "no value whatsoever" (ein lo damim) is a profound legal fiction. In the real world, a piece of chametz (leavened bread) on Pesach might have a high market price, yet the law views it as a phantom. The Maggid Mishneh explains this by noting that kiddushin requires a transfer of mamon (monetary worth). If the Torah effectively "nullifies" the object's utility, it strips the object of its character as money. This forces us to define "value" not by what others are willing to pay, but by what the law permits one to keep.

Insight 2: The Cheftza vs. Gavra Tension

The commentaries, particularly the Kin'at Eliyahu, identify a crucial friction: is the problem with the cheftza (the object itself) or the gavra (the person receiving it)? If the object is forbidden by Rabbinic decree, does it lose its value for everyone, or just for the one who cannot use it? The Beit Shmuel notes that if the object is forbidden, the woman has not received anything she can actually hold or use. Thus, the kiddushin fails because the "gift" is an empty gesture. The debate here centers on whether the marriage is a contract of exchange or a performance of ritual law.

Insight 3: The Boundary of Rabbinic Authority

The text creates a distinction between Torah prohibitions and Rabbinic decrees. Rambam holds that even Rabbinic prohibitions can render an object "worthless" for marriage. This is a bold assertion of the scope of Rabbinic power. The tension here lies in the Kessef Mishneh’s pushback: Rav Yosef Karo wonders if a Rabbinic prohibition is really strong enough to negate a scriptural transaction. The underlying question is: can a later legislative act (the Rabbis) retroactively strip an object of its status as "money" in the eyes of the Torah?

Two Angles

The Rambam’s Essentialist View

The Rambam argues that "value" is tied to the permissibility of usage. If an object is forbidden, it is legally nonexistent as currency. Therefore, using it for kiddushin is like trying to pay a debt with a dream; the marriage is void from the start. He prioritizes the sanctity of the kiddushin process, ensuring that the foundation of a marriage is built upon things that are permitted and holy, not illicit debris.

The Rabbenu Asher (Rosh) Counter-View

Rabbenu Asher argues that the kiddushin is valid if the object has intrinsic market value, even if the Sages forbade its usage. For him, the law of kiddushin is a transaction of value, and the Sages’ prohibition is merely a secondary restriction on behavior. If the item is "money" in the marketplace, it is "money" for the marriage. He separates the commercial validity of the object from the ritual prohibition of its enjoyment, allowing for a more flexible, perhaps more pragmatic, definition of the transaction.

Practice Implication

This passage teaches us that the "value" of our actions is often defined by the "legitimacy" of our resources. In daily decision-making, we are encouraged to ask: "Is the foundation of this commitment built on something I truly possess?" If we "consecrate" our time, our energy, or our resources to a project or relationship using "illicit" means—whether stolen, forbidden, or ethically compromised—the Rambam warns us that the bond may be built on a void. In a practical sense, it reminds us to ensure that our contributions to any partnership (whether professional or personal) are "permitted" and "clear," so that the agreements we make are standing on solid, unassailable ground.

Chevruta Mini

1. If you give someone an object that is forbidden to you but permitted to them, have you given them "value"? Why or why not?
2. Does the validity of a contract depend on the intrinsic worth of the payment or the permissible worth of the payment? How does this change your view of modern-day "compensation"?

Takeaway

True value in the eyes of the law is not determined by the price tag, but by the permissibility of the object; if you cannot use it, you cannot use it to build a sacred bond.
