Mishneh Torah, Marriage 1

Sugya Map

• Core Issue: The ontological shift of Kiddushin—from pre-Sinaitic bi'ah (act-based) to post-Sinaitic kinyan (formal acquisition).
• Primary Sources: Deuteronomy 22:13; Kiddushin 2a, 4b; Mishneh Torah, Hilchot Ishut 1:1–4.
• Nafka Minot:
  • The Nature of Pre-Sinaitic Marriage: Is it eishut (status) or merely zanut (licentiousness) that was elevated to eishut?
  • Biblical vs. Rabbinic: The status of Kiddushei Kesef (Money Acquisition) as d'oraita vs. midivrei soferim.
  • Shniyot: The scope and authority of Rabbinic prohibitions in arayot.

Text Snapshot

• "קודם מתן תורה... בועלה בינו לבין עצמו" (Marriage 1:1): The Rambam emphasizes the lack of formal kinyan. The Steinsaltz nuance captures the akrai (haphazard) nature of this encounter.
• "ושלש דרכים הן" (Marriage 1:2): The Rambam lists kesef, shtar, bi'ah. Note the dikduk: Rambam frames the acquisition as a "positive commandment" (mitzvah aseh), a framing that forces the Nachal Eitan to reconcile how an incomplete act (betrothal without consummation) constitutes a finished commandment.
• "ובכסף מדברי סופרים" (Marriage 1:2): The Tziunei Maharan provides a critical chiddush: midivrei soferim does not mean "Rabbinic"; it refers to the mode of derivation (exegesis) rather than the source (divine authority).

Readings

1. The Maggid Mishneh: The Taxonomy of "Midivrei Soferim"

The Maggid Mishneh defends Rambam’s controversial classification of Kiddushei Kesef as midivrei soferim. His chiddush rests on the Rambam’s principle in Sefer HaMitzvot (General Principle 2): any law not explicitly written in the Torah, even if derived via the thirteen middot (hermeneutics), is linguistically labeled midivrei soferim.

This is not a demotion of the law's binding nature; it is a linguistic designation. The Maggid Mishneh argues that the Torah provides the authority to create the kinyan, but the Sages identify the mechanism (money). Thus, the status is Biblical, but the pedigree is rabbinic-hermeneutic.

2. The Tzafnat Pa'neach: The Ontology of Pre-Sinaitic Bi'ah

The Tzafnat Pa'neach (Rogatchover Gaon) engages in a high-level analysis of the pre-Sinaitic state. He questions whether bi'ah before the Torah constituted ishut (marriage status) or mere zanut.

The Rogatchover notes that Rashi (Sanhedrin 57a) implies pre-Sinaitic relations were not ishut. However, he counters this with the Yerushalmi’s discussion on kavanah (intent). If the Bnei Noach require kavanah to establish ishut, then bi'ah without intent remains zanut. The chiddush here is that Kiddushin post-Sinai isn't just about adding witnesses; it is an ontological transformation where the act of bi'ah is "re-coded" by the Torah from a biological event into a legal-sanctifying act.

3. The Nachal Eitan: The "Incomplete" Mitzvah

The Nachal Eitan addresses the Kessef Mishneh’s difficulty with Rambam calling kiddushin a mitzvah aseh when the act remains prohibited until nissu'in. He explains that the mitzvah is the act of acquisition itself. Even though the reshut (permission) for bi'ah is delayed, the kinyan is complete as a legal entity. He provides a fascinating parallel: Rabban Yochanan ben Zakkai’s decree on the Omer (Menachot 68) is technically d'oraita in essence, even if framed as a "decree" (takkana). This supports the Rambam’s view that the language of the Sages often masks the Biblical strength of the rule.

Friction: The Problem of the Kiddushei Kesef Source

The Kushya: The Ra'avad attacks the Rambam: If Kiddushei Kesef is derived from gezerah shavah (Kiddushin 4b), it is d'oraita. Why does the Rambam label it midivrei soferim?

The Terutz: We must distinguish between Divrei Torah (explicit text) and Divrei Soferim (derived by the Sages). The Tziunei Maharan citing the Ritba (Sukkah 43a) provides the most elegant resolution: "When we say midivrei soferim, it is not literally 'Rabbinic law,' but rather that it is not explicitly written in the parashah of the day." The Kessef Mishneh and Nachal Eitan converge here: The Rambam is a formalist. If the Torah doesn't say "Take money for a wife," but the Sages deduce it, the source is the Sages' intellectual labor (the Soferim). The obligation is Divine, but the origin of the specific halacha is the interpretive tradition of the Sages.

Intertext

• SA (Even HaEzer 26:1): The Shulchan Aruch codifies the Rambam, maintaining the three-fold kinyan structure. The friction between bi'ah as a kinyan and bi'ah as nissu'in remains the bedrock of marriage law.
• Tosefta Kiddushin 1:1: The Tosefta prefigures the Rambam’s distinction, noting that the Sages were the ones who elevated the bi'ah from a simple physical act to a kiddushin entity, reinforcing the Nachal Eitan’s point about the "legislative" role of the Sages within the Torah's framework.

Psak/Practice

In contemporary practice, Kiddushei Kesef (the ring) is the standard. The meta-psak takeaway is that the "Rabbinic" nature of the money-based kinyan does not undermine its validity. Rather, it underscores the necessity of Da'at (legal intent) defined by the Sages.

Practice: One must ensure the kiddushin is not merely an exchange of value but a kinyan of status. If the money is not shaveh perutah (worth a penny), the kiddushin is void, not because it failed to be a "sale," but because it failed to meet the Shiur (measure) established by the Soferim to constitute the kinyan.

Takeaway

Kiddushin is the bridge between the pre-legal animalistic drive and the Sinaitic sanctified bond; the Sages do not add to the Torah, they provide the language through which the Torah’s intent becomes an actionable reality.
