Does the Mishna's 'ein madlikin' mean these wicks and oils are forbidden for Chanukah (חנוכה), or just that one doesn't fulfill the mitzvah (מצוה) properly? The shiur develops a chiddush that the prohibition depends on whether the light has an inherent tendency to fail versus being extinguished by external factors. This distinction reframes when one bears responsibility for maintaining Chanukah lights and when a bracha may be recited.
This shiur provides an in-depth analysis of Masechta Shabbos (שבת) 21a-b, focusing on the laws regarding which wicks and oils may not be used for Chanukah (חנוכה) lighting. Rabbi Zweig begins by examining the ambiguous meaning of 'ein' (not/don't) in the Mishna's statement 'ein madlikin' - whether it means forbidden (assur) or simply that one doesn't fulfill the mitzvah (מצוה) properly. He explores the fundamental question of whether the prohibition has different meanings on Shabbos versus regular weekdays. The shiur delves into the Rambam (רמב"ם)'s position regarding 'shema yata' (lest one come to adjust the flame), analyzing when this concern applies. Rabbi Zweig questions whether the shema yata prohibition applies equally to lights used for illumination versus decorative lights that one doesn't actively use. He examines Rav Huna's statement about 'kofsa zokegla' (if it dims and goes out) and analyzes Rashi (רש"י)'s interpretation.

How can Shabbos observance atone for the idolatry of Enosh's generation? The Rambam's reading shows that generation sought God through physical intermediaries rather than direct connection. Proper Shabbos observance creates authentic divine experience that naturally displaces attraction to spiritual substitutes - like tasting real coffee exposes ersatz as meaningless.
Why does the Gemara say one Shabbos protects from Amalek while two Shabboses bring redemption? The shiur applies a principle from Kiddushin about repetition changing psychology: the first time doing anything is experimental, but the second demonstrates genuine desire. True Shabbos connection with Hashem requires moving beyond spiritual curiosity to authentic internalization.
Why does the Gemara pray to be 'among those who eat three meals on Shabbos' rather than simply to fulfill the mitzvah? The shiur develops that Shabbos eating means 'tasting the day itself' - mindful appreciation that connects us to Shabbos's spiritual quality. This requires discipline and community support, with three meals corresponding to distinct phases of Shabbos time.
Why does the Gemara present a kal v'chomer for chuppah making kiddushin based on kesef not being maichel b'terumah, only to reject it? The shiur reveals that even the rejected kal v'chomer establishes a fundamental yesod: kiddushin is a kinyan for ishus (marital relationship), not merely a kinyan in hilchos kinyanim. The second kal v'chomer—from chuppah being gomeres—raises Tosafos's famous question.
Is the kesef used in kiddushin a true kinyan (acquisition), or merely a symbolic means of establishing marriage? The shiur analyzes multiple interpretations of the Gemara's derivation from ki yikach ki'ach mi'Sayeffron, exploring whether marriage constitutes ownership, and develops three fundamental approaches: (1) The Gemara proves ishus is a kinyan, (2) ishus is not a kinyan but uses kinyan-like means, or (3) ishus is a kinyan but the kesef may not be a ma'aseh kinyan. The Rambam's position—calling kesef "midivrei sofrim"—is explained as distinguishing between cross-referencing concepts versus borrowing terminology.
Why does the Mishna alternate between the language of "kinyan" (acquisition) and "kiddushin" (sanctification) when describing marriage? The shiur develops a fundamental distinction: marriage has two separate aspects—a kinyan dimension (ownership) and a kedusha dimension (sanctified relationship). Either aspect can initiate the bond, and understanding this dual nature resolves multiple textual and halachic questions throughout the sugya.
Does kiddushei shetar require a shevah pruta? The Ran presents two approaches to the Rif's position. The shiur develops the Ran's second pshat that shetar kiddushin functions as a hachnah (exchange) rather than a mere kinyan nesina. This reading has profound implications for isuri hana'ah, mechubar, and the relationship between kesef and shetar.
