Mishneh Torah, Rest on the Tenth of Tishrei 1-3

Sugya Map

• Issue: The nature of the commandment to rest on Yom Kippur (Shabbat Shabbaton) and the scope of "affliction."
• Nafka Mina: Whether the prohibitions (work, eating, washing, etc.) are derived from the Shabbat Shabbaton verse or are distinct Rabbinic decrees.
• Primary Sources: Leviticus 23:32; Yoma 74a-81b; Mishneh Torah, Hilchot Shevitat Asor 1:1-3.

Text Snapshot

"It is a positive commandment to refrain from all work... as [Leviticus 23:32] states: 'It shall be a Sabbath of Sabbaths for you.'" (Hilchot Shevitat Asor 1:1)

Nuance: Rambam identifies Shabbaton as the source for the positive commandment of cessation. The term Shabbaton functions as a linguistic bridge between the sanctity of Shabbat and the unique sanctity of Yom Kippur.

Readings

• Ramban (Commentary on Lev. 23:24): Argues that the Sages equate all festivals through the concept of Shabbaton, asserting that the obligation to cease work on all holidays is rooted in this verse.
• Rambam (Sefer HaMitzvot, Positive 165): Views the prohibition of work on Yom Kippur as an independent positive commandment, distinct from the negative prohibition, emphasizing that the cessation itself constitutes a sanctified act of rest.

Friction

• Kushya: The Lechem Mishneh asks: if Shabbaton is the source for cessation of work, why does the Sages' interpretation of Shabbaton also extend to secondary prohibitions like k'nivah (trimming vegetables) and muktzeh?
• Terutz: The term Shabbat refers to the fundamental cessation of labor, while Shabbaton (the "Sabbath of Sabbaths") functions as the expansive authority to categorize all derivative "rest-breaking" activities as forbidden.

Intertext

• Parallel: Shabbat 115a confirms that Shabbaton serves as the biblical source for the prohibition of activities that are not technically melachot but violate the spirit of "rest."
• Cross-ref: SA Orach Chayim 611 codifies the Rambam’s view that the "affliction" of the soul is not merely a negative prohibition but a positive performance of the day’s required state.

Psak/Practice

The Rambam’s heuristic is that there is no difference between Shabbat and Yom Kippur regarding the definition of labor, only the severity of the penalty. In practice, this means we treat the "atmosphere" of Yom Kippur with the same strictness as Shabbat. The prohibition of washing, anointing, and wearing shoes, while technically Rabbinic or asmachta, is treated with the same stringency as the Torah-level fast to ensure the total "affliction" (inui) of the soul.

Takeaway

Yom Kippur is not merely a "fast day"; it is an ontological state of total cessation. By resting from work and afflicting the body, we mimic the state of the soul, detaching from the physical world to achieve atonement.
