Kiddushin 6a: Territorial Validity of Lashon HaKiddushin

The shiur opens with an extended analysis of the Ramchal's framework in Derech Hashem (ה׳) for determining the severity and nature of punishment. The Ramchal identifies four factors: (1) the magnitude of the cheit itself (godol ha'onesh), (2) the frequency of occurrence (rov imtzo), (3) the strength of the person's drive to commit it (rov hasosim badavar), and (4) the ease of committing the act undetected (kalos asos hama'aseh). Rabbi Zweig works through the logic of these categories, noting that capital punishment (misas beis din) requires a tremendous heftzeh—a genuine societal loss—and cannot be justified by frequency or ease alone. He distinguishes between Jewish and Gentile law, noting that a Jew is only killed when there is a major loss to the world, since killing a human being who has demut Elokim is itself a tremendous depletion of the world's resources. By contrast, a Gentile, who has tzelem Elokim but not demut Elokim, can be executed for lesser sins like theft, reflecting that he is a "guest" in the world rather than a citizen with inherent rights. The shiur then transitions to Kiddushin 6a. The Gemara (גמרא) discusses whether saying "harei at charufosi" creates kiddushin. In Yehuda, the word "charufa" means "erusin," so the kiddushin would be valid. The Gemara rules that this only works "be'Yehuda"—in the place where charufa has that meaning. Rabbi Zweig examines the Mishnah (משנה) Berurah's ruling in the Beer HaGolah that this is a strict geographic requirement: if four Israelis from Yehuda are on vacation in France and perform kiddushin using "charufosi," it is invalid, even though all four parties (man, woman, two witnesses) speak the same Hebrew dialect and understand the term perfectly.
