Mishneh Torah, Oaths 1-3

Sugya Map

• Issue: The intersection of Sh'vuat Bitui (oath of expression) and Sh'vuat Shav (oath in vain).
• Nafka Mina: Whether a false statement regarding the past/future triggers a korban (guilt offering) or malkot (lashes), contingent on the oath's category and the presence of God’s Name.
• Primary Sources: Lev. 5:4, Ex. 20:7, Shavuot 20a-21a, Rambam Hilchot Shevuot 1:1–3.

Text Snapshot

• Rambam 1:3: "If he willfully swears falsely, he is liable for lashes... If he does so inadvertently, he must bring an adjustable guilt offering."
• Nuance: Bitui (expression) implies a verbalized act. Rambam emphasizes lashon hakodesh is not the exclusive medium; the intent and the mention of God’s name (or descriptive terms) elevate a statement to a binding oath.

Readings

• Ra'avad (ad loc. 1:11): Challenges the necessity of God’s name for all liability. He posits a distinction: one transgresses the prohibition by swearing falsely, but malkot specifically requires the mention of the Divine Name.
• Radbaz (ad loc. 1:10): Defends Rambam’s strictness, arguing that for the gravity of a sh'vuah to take effect, the invocation of the Divine is structurally necessary to transition speech from mere assertion to Shevuah.

Friction

• Kushya: If an oath requires "the heart and lips to be in concord" (1:15), why is one liable when a tax collector or gentile forces the oath (1:13)? Is the intent not vitiated by duress?
• Terutz: The Rambam (1:13) posits that even under duress, one retains an "inner sanctuary" of intent. By mentally shifting the oath's object to something permissible (e.g., swearing not to eat "meat," but intending "pork"), the oath remains technically truthful and exempt from sh'vuat sheker.

Intertext

• Nedarim 25a: Mirrors the Rambam's insistence on the "intent of the administrator" in judicial settings, effectively stripping the oath-taker of their private mental reservations.

Psak/Practice

The Rambam’s psak creates a meta-heuristic for modern litigation: when taking an oath in a secular court, one must be precise. Because "Yes, yes" or "No, no" combined with the intent of an oath counts (1:9), casual affirmation in a legal setting carries the weight of a scriptural sh'vuah.

Takeaway

An oath is not merely a linguistic performance; it is the alignment of lashon (lips) and lev (heart) under the canopy of the Divine Name. If the heart is not in it, the oath is a shav (vain) act; if the lips are not in it, it is a non-event.
