Mishneh Torah, Fringes 1

Sugya Map: The Ontology of Tzitzit

• Issue: The legal status of the "number" of strands in a tzitzit assembly—specifically, whether fixed requirements are de-oraita (Torah-level) or de-rabbanan (Rabbinic).
• Nafka Mina: Whether adding strands (e.g., beyond eight) constitutes a violation of Bal Tosif (adding to the Torah’s mitzvot).
• Primary Sources: Mishneh Torah, Hilchot Tzitzit 1:1; Menachot 39a, 41b; Shulchan Aruch, Orach Chayim 11:12.

Text Snapshot

• MT 1:1: "The Torah did not establish a fixed number of strands for this tassel (anaf)..."
• Leshon Nuance: Rambam uses anaf (branch) to denote the hanging portion. The Kesef Mishneh (ad loc.) notes a tension: if the Torah implies a "braid" (g’dil), why isn't the count de-oraita? Rambam classifies it as divrei sofrim (Rabbinic), even if derived via midot (hermeneutics).

Readings

• Kesef Mishneh: Argues that Rambam treats any derivation not explicit in the pashut (literal) reading—even if achieved through the 13 midot—as divrei sofrim.
• Tzafnat Pa'neach (Rogatchover): Suggests that the anaf refers specifically to the loose, unbound portion. Rambam’s innovation is that while the g’dil (the knot/binding) is the Torah’s mechanism, the length/count of the hanging anaf is inherently undefined, rejecting Rashi’s stricter requirement.

Friction: The Bal Tosif Paradox

• Kushya: If the count is only de-rabbanan, how can Shulchan Aruch HaRav (11:1) claim that adding a 9th strand violates Bal Tosif?
• Terutz: The prohibition of Bal Tosif applies to the mitzvah structure once defined by the Sages as the "essential form" (tzu-rat ha-mitzvah). By standardizing the eight-strand model, the Rabbis integrated it into the Torah framework, rendering deviations a violation of the integrity of the command.

Intertext

• Parallel: Hilchot Tefillin 4:4. Just as techelet and white strands are independent yet form one mitzvah, so too the head and arm tefillin are distinct entities unified by a single objective: remembrance.

Psak/Practice

• Meta-Psak: In the absence of techelet, the anaf composition follows the Minhag. While Rambam is lenient regarding the anaf length (as long as it allows for a loop), the Shulchan Aruch (11:4) mandates the Rabbenu Tam standard (12 fingerbreadths) as the baseline for kashrut.

Takeaway

Rambam’s classification of Rabbinic law as "Rabbinic" even when derived from Torah hermeneutics serves to preserve the pashut of the Written Law, while simultaneously granting the Sages total authority to define the "shape" of the commandment.
