The Metaphysics of Matrimonial Acquisition: Why the Torah Objectifies Marriage
The conceptual foundation of Jewish marriage is rooted in the verse describing the act of betrothal:
כי יקח איש אשה – When a man will acquire a woman[1].
The Torah deliberately employs the singular tense—one (1) man taking one (1) woman. Yet, Halaĉa historically recognized the ability of a man to marry multiple wives, provided he had the financial means to support them[2]. This raises a fundamental textual and philosophical question: If the defining verse of marriage is written in the singular, from where is the concept of taking multiple wives derived? Furthermore, why does the Torah utilize the cold, commercial language of acquisition (קנין) to describe the most intimate and holy of human relationships?
Rejecting Standard Textual Proofs for Multiple Wives
To locate the source permitting multiple wives, one might attempt to look at instances in the Torah where multiple wives are explicitly mentioned. However, upon closer inspection, these cases fail to serve as a proper Halaĉic paradigm for standard marriage.
1. The Captive of War (יפת תואר)
The Torah discusses a scenario involving two (2) wives in [Devarim 21:15]:
כי תהיין לאיש שתי נשים האחת אהובה והאחת שנואה – If a man will have two (2) wives, the one (1) beloved and the one (1) hated
While this verse acknowledges a reality of two (2) wives, Midrashic tradition notes this section is juxtaposed with the preceding laws of the captive woman (יפת תואר), indicating that this is a compromised marriage permitted only כנגד יצר הרע. More importantly, from a legal perspective, the verse states תהיין (will be) rather than using a derivative of יקח (will acquire). The initial physical connection in a time of war lacks any mutual consent or act of acquisition. Because its foundation bypasses the standard mechanism of קידושין entirely, it cannot serve as the source for standard, voluntary marriage.
2. The Hebrew Maidservant (אמה העבריה)
Another potential source is [Shemos 21:10], discussing a maidservant who was designated as a wife:
אם אחרת יקח לו שארה כסותה ועונתה לא יגרע – If he takes another for himself, her food, her clothing, and her marital relations he shall not diminish
This also fails as a proof-text. The initial transaction that brings the maidservant into the master’s domain is an acquisition for servitude, not for matrimony. When she is later designated as a wife (ייעוד), it is a conversion of status. It completely lacks the standalone, dedicated act of כי יקח that defines the formation of a normal marriage.
The Core Thesis: Acquisition as an Exercise of the Soul
If the permission for multiple wives cannot be derived from these specific cases, it must be inherent to the mechanism of the acquisition itself.
To understand this, we must ask why the Torah objectifies women by treating marriage as a purchase. The answer lies in the accolades we give to G-d. Daily, we refer to G-d as קונה הכל, and in the Torah, He is described as:
קונה שמים וארץ – Acquirer of heaven and earth[3].
Why is “buying” an accolade for the Creator, who already owns everything by virtue of having made it? The explanation is that creating is a functional relationship, like a craftsman to a tool. Acquisition, however, requires a deliberate exercise of will. By “acquiring” the universe, G-d exercises true choice, forging a bond that infuses the physical world with sentimental value.
The same applies to human relationships. The Torah allows for sexual connection, but biological mating is common across the animal kingdom. To elevate this connection to קידושין (sanctification), the Torah demands an acquisition. The act of choosing to acquire this specific person amongst all others is an exercise of the soul on the deepest level.
Because marriage operates on the legal chassis of a financial acquisition, there is naturally no “one-marriage-per-customer” limit. A person can execute this willful choice as many times as they wish, which perfectly explains why Rava conditioned taking additional wives purely on the husband’s financial resources, rather than his physical stamina. You cannot acquire what you cannot afford to maintain.
The Challenge: Simultaneous Acquisition
This thesis, however, faces a severe stress test in Talmudic law.
If the entire purpose of utilizing acquisition is to ensure a singular, focused exercise of the soul, what happens when a man attempts to betroth multiple women at the exact same moment?
The Gemara[4] rules that a man can indeed acquire two (2) wives simultaneously with a single action of handing over an item. At first glance, this seems to reduce the holy act of marriage to a bulk commercial purchase, destroying the concept that each marriage must be a singular, willful choice.
The Resolution: The Requirement of Distinct Value
The resolution to this problem is found in the specific financial requirement the Gemara places on this simultaneous betrothal.
In standard commercial law (Ĉoshen Mishpat), if a person wishes to buy a bulk lot of items—such as a basket of ten (10) apples—they only need one (1) Pruta. A single coin legally acquires the entire bundle.
However, in the laws of קידושין, the Gemara states that if a man gives an item worth only one (1) Pruta to two (2) women simultaneously, אינן מקודשות – they are not married. To successfully acquire two (2) wives at once, the item handed over must be worth a minimum of two (2) Prutos—one (1) distinct unit of value for each woman.
This Halaĉic distinction provides the ultimate proof. By legally rejecting the “bulk purchase” of wives and demanding a distinct, legally severable unit of value for each woman, the Oral Law perfectly preserves the exact nature of the verse: כי יקח איש אשה.
Even when temporally simultaneous, the transaction is conceptually and metaphysically partitioned. It is not one (1) purchase of two (2) women; it is two (2) distinctly singular transactions occurring at the same time. The singular phrasing of the verse is not a numerical cap on a man’s lifetime capacity, but a strict definition of the nature of the bond. Every marriage, without exception, must be an individual, legally distinct act of willful acquisition by the soul.
