Rabbi Zweig explores why the prohibition against taking God's name in vain is the third commandment, examining the profound spiritual nature of oaths as expressions of the soul rather than mere speech.
Rabbi Zweig presents a comprehensive analysis of the Third Commandment, "Lo sisah shem Hashem (ה׳) elokecha lashav" (You shall not take the name of the Lord your God in vain), addressing several fundamental questions about its placement and severity. He begins by noting that the same word "lashav" is used for both false and unnecessary oaths, questioning why identical terminology describes these different violations. Additionally, he examines why the Torah (תורה) uses "lo sisah" (do not elevate/carry) rather than the more common term for swearing. The core of his analysis centers on why this commandment appears third, seemingly more fundamental than Shabbos (שבת), and why it carries such severe punishment - being the only commandment where God declares "ki lo yenaka" (He will not cleanse). Rabbi Zweig develops a profound understanding based on the verse "Vayipach ba-apav nishmas chaim, vatehi adam lanefesh chaya" - God breathed into man the soul of life, and man became a living soul. The Targum translates this as "leruach memalela" - the spirit that speaks. Rabbi Zweig explains that while all creatures communicate, humans possess a unique ability: speech can express either bodily needs (like animals) or the divine soul within us. When making an oath (shevua), a person elevates himself ("sisah") to express his eternal essence - the nishmas chaim that God breathed into him. This explains why "lo sisah" specifically means to elevate oneself inappropriately. The severity becomes clear: when someone makes a false or unnecessary oath, they are misusing the highest spiritual faculty - the ability to express the divine spark within. Whether the oath is false or unnecessary, the core violation is identical: wasting this sacred power of soul-expression for meaningless purposes. This is why both are called "lashav" - ultimately both represent a squandering of our divine potential. Rabbi Zweig connects this to the Yerushalmi's account of Rabbi Shimon bar Yochai wishing for two mouths - one for Torah study and one for mundane speech. Unlike other physical functions that serve both holy and mundane purposes, speech operates on fundamentally different levels: body-language versus soul-language. Torah study should emerge from our nishama, while ordinary conversation stems from physical needs. The analysis extends to understanding why Hataras Nedarim (annulment of vows) precedes Rosh Hashanah and why Kol Nidre opens Yom Kippur. These practices purify our capacity for soul-expression, essential for the spiritual communication required during the High Holy Days. The power of nedarim (vows) demonstrates this concept practically - when someone declares an object forbidden through a neder, it actually acquires sacred characteristics, requiring a temple sacrifice if violated, because an eternal expression has emerged from the person's mouth. Rabbi Zweig concludes that our spiritual destiny involves learning to consistently express our souls through speech rather than merely our physical wants. The Third Commandment's placement reflects its fundamental importance: after establishing God's existence and rejecting false gods, we must properly honor the divine element within ourselves that God has given us the ability to express.
