Mishneh Torah, Sabbath 27

Sugya Map

• Primary Issue: The ontological status of Techum Shabbat (Sabbath limits). Is it de-Oraita (Biblical) or de-Rabbanan (Rabbinic)?
• The Rambam’s Stance: Explicitly de-Oraita up to 12 mil (the camp of Israel in the desert). Violating 12 mil constitutes a Biblical transgression punishable by lashes.
• Nafka Mina:
  • Leniency: If de-Rabbanan, one follows the lenient view in cases of doubt (sefeka de-rabbanan lekula). If de-Oraita, one must be stringent.
  • Conflict with Mitzvah: To what extent does a mitzvah (like Kiddush HaChodesh or Pikuach Nefesh) override the prohibition?
  • The "Place" Concept: Does the city wall define the limit, or does the individual’s physical footprint?
• Primary Sources: Exodus 16:29, Eruvin 17a, Eruvin 43a, Eruvin 45a, Mishneh Torah, Sabbath 27.

Text Snapshot

"A person who goes beyond [his] city's Sabbath limit should be punished by lashes, as Exodus 16:29 states: 'No man should leave his place on the seventh day.' [The term] 'place' refers to the city's Sabbath limits." (Mishneh Torah, Sabbath 27:1)

Leshon Nuance: Note Rambam’s choice of laka (lashes). By grounding the issur in the literal reading of the verse, he bypasses the asmachta (allusion) school of thought common among other Rishonim. The phrase yitzi ish mimkomo is treated not as a poetic restriction, but as a formal lav (negative prohibition).

Readings

1. The Ramban (Milchamot HaShem, Eruvin)

The Ramban challenges the Rambam’s assertion that Techumin is de-Oraita. He argues that the Babylonian Talmud consistently treats Techumin as a Rabbinic institution. He views the Rambam’s reliance on the Jerusalem Talmud and the specific measure of 12 mil as an outlier. For Ramban, the verse in Exodus is an asmachta, a support structure for a Rabbinic decree, not the source of the law itself.

2. Ohr Sameach (Sabbath 27:1)

The Ohr Sameach defends the Rambam by proposing a structural model: The Torah restricts the movement of the Jew as it restricts his labor. Just as the Sabbath is a "prison" of sorts for labor, it is a boundary for the body. He posits that the mil measurement is the "natural" space for a person. He suggests that the Rambam differentiates between the Biblical prohibition (12 mil) and the Rabbinic expansion (2,000 cubits), arguing that the Rabbis only possess the power to constrain the individual within the Biblical limit, not to create a new issur where none existed.

Friction

The Strongest Kushya: If Techum is de-Oraita (12 mil), why does the Gemara in Yoma 66b and Keritot 14a debate whether Eruv (the practice of extending limits) applies on Yom Kippur? If the limit is Biblical, how can a Rabbinic tool like Eruv effectively "uproot" a Biblical prohibition?

The Terutz: The Seder Mishnah argues that the Eruv does not "uproot" the Biblical prohibition but rather refines the definition of "place." By placing food at a point, one effectively relocates the center of their "encampment." Thus, they are not violating the Techum of their original home; they have legally established a new home for the duration of the Sabbath. The Tzafnat Pa'neach adds that this applies only to the Rabbinic 2,000-cubit limit, which the Rabbis were empowered to modify, whereas the 12 mil absolute limit remains fixed as the outer Biblical boundary.

Intertext

• Tanakh: Numbers 35:5 (the pasture lands) is utilized by the Rambam to explain the 2,000-cubit measure. The interplay between the "city" and the "pasture land" mirrors the distinction between the reshut hayachid and the surrounding space.
• SA/Responsa: Shulchan Aruch, Orach Chayim 404:1 largely defaults to the de-Rabbanan view, yet the Rama notes the Rambam’s stringency. This reflects the meta-halachic reality: we treat Techumin as de-Rabbanan for practical rulings, but observe it with the gravity of a Biblical commandment due to the sheer number of authorities who fear the Rambam’s classification.

Psak/Practice

In practice, the Techum is treated as de-Rabbanan for the purpose of sefeikot (doubts). We do not lash those who breach the 2,000-cubit limit, confirming the consensus that the "2,000-cubit" restriction itself is a gezeirah of the Sages. However, the Rambam’s framework remains the "meta-halachic" floor: even if the 2,000-cubit limit is Rabbinic, the concept of restricted movement is rooted in the Torah, imposing a duty of respect for the Sabbath space.

Takeaway

The Rambam’s insistence on a Biblical Techum forces us to see the Sabbath not merely as a day of "not doing," but as a day of "being in place." Our limits are not just a list of rules, but an extension of the desert camp—a sacred, defined geography that anchors the soul.
