Why aren't women obligated in Hallel on Chanukah (חנוכה) if they're obligated in lighting based on 'af heim hayu b'oso hanes'? The Rambam (רמב"ם) identifies two distinct Chanukah miracles: the military victory (Hashem (ה׳)'s war through the Kohanim) and the Temple rededication with lasting oil. Women participated in the rededication like the original Mishkan, obligating them in ner Chanukah, but not in Hallel commemorating the divine military victory.
Rabbi Zweig begins with a longstanding question about the Al Hanissim prayer - why do we praise Hashem (ה׳) for 'reshaim biyad tzaddikim' and 'zeidim biyad oskei Toratecha'? The answer emerges from understanding the true nature of the Chanukah (חנוכה) miracle and the Rambam (רמב"ם)'s complex presentation of the laws. The lecture analyzes a famous question on the Rambam: why doesn't he rule that women are obligated in Hallel on Chanukah if they are obligated in ner Chanukah based on 'af heim hayu b'oso hanes'? Through careful examination of Hilchos Chanukah and Hilchos Brachos, Rabbi Zweig demonstrates that the Rambam identifies two distinct miracles and corresponding obligations. The first miracle was the military victory, where the Chashmonaim (as Hashem's direct agents from Shevet Levi) overcame the Greeks - this was Hashem fighting the war directly, not a human victory. This generates obligations of Hallel, simcha, and pirsumei nisa (publicizing the miracle) through lighting outside. The second miracle occurred when Klal Yisrael established a malchus and rededicated the Mishkan, discovering oil that lasted eight days instead of one. This generates the core obligation of ner Chanukah. Women are obligated in ner Chanukah because they participated in the rededication of the Mishkan (similar to their role in building the original Mishkan), making this 'af eim hayu b'oso hanes.' However, women are not obligated in Hallel because the military victory was Hashem's war fought through His special legion (the Kohanim), not something in which women participated. The Rambam's language reveals this distinction: he calls ner Chanukah a 'chovah' (obligation) but describes Hallel as merely 'gomer es haHallel' (completing the Hallel) - a mitzvah (מצוה) but not an obligation. The bracha on Hallel is compared to eruv and the second reading of Megillah, both of which are mitzvos but not chovos. This understanding resolves the apparent contradictions in the Rambam's presentation and explains why he discusses the bracha question for Hallel separately from ner Chanukah, even though both are d'rabbanan.

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.
When an animal damages crops, the Torah prescribes a unique payment formula based on multiplying the damaged area by sixty. Does this formula redefine the actual loss, or does it merely create a payment mechanism that still acknowledges the full damage sustained? The Gemara explores whether someone who ate in doubt should pay the higher-quality amount, examining how the principle of motzi me-chaveiro alav haraya applies when payments fall within the range of actual loss.
What makes testimony valid when different witnesses testify to different parts of the same event? The Gemara debates whether the principle of "davar v'lo chatzi davar" (complete testimony, not partial) disqualifies witnesses who testify separately to theft and slaughter. Rashi's approach reveals that the issue is not merely combining elements, but whether each witness's statement is independently meaningful.
Why is a ganav who sells a stolen animal on Shabbos exempt from the fourfold/fivefold payment? The shiur analyzes whether this exemption stems from kam lei b'derabbah or from the absence of a valid mechira. The Rashba's principle that matana resembles mechira when it is "nishtarish b'chet" is explored, along with the Rambam's position on hekdesh and the distinction between giving to bedek habayis versus mizbe'ach.
When a ganav shechts a stolen animal l'avodah zarah, why isn't he patur from payment since it's already isur hana'ah? The shiur explores the fundamental machloket Rashi-Tosafot on whether the isur derives from the act of shechita or from the din shechita itself. The Gemara's application of davar garem be'mamon ke'mamon domi extends the analysis to when borrowed animals become niskal.
