Why is a dried lulav (yoveish) disqualified all seven days when hidur mitzvah ordinarily isn't me'akev? The shiur analyzes three approaches: Rashi holds the seven-day requirement flows from zecher l'mikdash where hidur mitzvah is me'akev because of kavod Shem Shamayim. Tosafot distinguishes ikar lekicha from hidur mitzvah. The Ramban learns the Gemara refers to the Torah-level mikdash obligation, creating a chakira between the gevulin mitzvah (lekachtem) and the mikdash mitzvah (u'smachtem).

Can one fulfill the mitzvah of lulav on Yom Tov Rishon with a stolen lulav if thieves cut it themselves or sell it to someone else? The shiur analyzes Rashi's two possible explanations—either yiush alone doesn't transfer ownership (requiring shinui reshus) or yiush does work but creates a mitzvah haba'ah b'aveirah problem—and explores the Gemara's statement that the lulav is "yiush in the hands of the thieves and shinui reshus in the hands of the buyer."
7 shiurim
When Chazal enacted Takanas Hashavim allowing one who built with stolen materials to compensate with money rather than dismantling, did they transfer ownership or merely exempt from returning the object? The shiur distinguishes two categories: where massive loss would discourage universal compliance (e.g., beams in a house), the Rabbis made it fully yours to prevent a bad precedent; where return is easy (e.g., sheni she'eino chozer), they merely permit monetary settlement without transferring title.
15 shiurim
Does the prohibition of dichuy (rejection) apply when a chefetz (object) becomes valid only after the mitzvah time begins? The shiur analyzes Rashi, Tosafos, and Rav Chananel to develop a fundamental chakira: is the zman (time) itself the mechayev (obligating factor) in mitzvah, or merely the opportunity to fulfill a pre-existing obligation? This distinction resolves the Gemara's proof from kisui hadam and addresses the Noda B'Yehuda's question about koton's validity for shechita versus tefillin.

The Gemara discusses adding a fifth species when the lulav is tied (meuged). Does tying create a halachic entity that makes adding a fifth species "kol hamosif goreia" (whoever adds, detracts)? The shiur develops the Rambam's position that agud creates a tziruf—the three species become one object for nanuim—and therefore adding a fifth is pasul, though not baltosif d'oraita.
8 shiurim
Are blackberries on a hadas merely a cosmetic blemish (psul hadar), or do they change it into a non-hadas (chasaron in the min)? The Gemara's proof from hilchos niddah that red berries share black's status suggests the issue is min, not beauty. This foundational chakira addresses the Magen Avrohom's question why the Rama rules differently for esrog spots (pasul all seven days) versus hadas berries (pasul only Yom Tov Rishon).

When does a listener need to answer "amen" after a bracha to be yotzei? The Rambam holds that when the mevarech makes the bracha for himself, the listener must answer amen to create his own bracha. But when the mevarech acts purely as a shaliach—making the bracha solely for the listener—shomea k'oneh applies and no amen is required. This directly contradicts the Tur's approach.

Why does the Rambam rule one makes "al netilas lulav" after picking up the lulav, contradicting his own principle that no bracha can be made after fulfilling a mitzvah? The shiur develops a yesod that the mitzvah of netilas lulav extends beyond the initial picking up—through the minhag Anshei Yerushalayim of continuous holding—making the bracha on the ongoing fulfillment, not a completed act.
3 shiurim
When exactly do you make the bracha on lulav—before touching it, after picking it up, or somewhere in between? The Gemara's principle of oiver la'asiyasan (don't pass over a mitzvah) appears straightforward, but Tosfos reveals a fundamental dispute: Does the bracha need to attach to the ma'aseh hamitzvah (the act itself) or to the kiyum hamitzvah (the fulfillment)? This analysis drives the halacha of when and how to recite al netilas lulav.

How can we derive halachos from Moshe killing the Egyptian when that Egyptian was guilty of other sins too? Torah study analyzes the divine text as wisdom, not historical documentation. Multiple legitimate interpretations coexist because we're learning from the Torah's infinite teachings, not reconstructing past events.
Why is a dried-out lulav (lulav hayovesh) invalid, and how can the Rambam rule it's kosher b'sha'as hadchak? The shiur distinguishes two independent dimensions in the mitzvah of lulav: netilas lulav (taking) and hallel (praise). A dried lulav fails only the hallel aspect ("lo hameisim yehallelucha") but remains valid for netilah, enabling the b'di'eved ruling without compromising Torah law.
Why does Rashi require the hadasim in the Gemara to be stolen from a Jew rather than a non-Jew? The shiur develops a fundamental distinction: gezel Yisrael is a bein adam l'chavero rooted in ownership rights, while gezel akum is a bein adam l'makom focused on the act of theft itself. This distinction explains Rashi's girsa and resolves questions about yiush, shinui reshus, and mitzvah ba'aveira.
Why does the Gemara discuss shinui kinyan when someone buys hadassim from a non-Jew for the lulav bundle? The shiur distinguishes two separate mitzvos: netilas lulav (taking) and hoshana (na'anu'im—waving). The Rambam's careful language reveals that agudah (binding) is only hiddur mitzvah for netilah, but is me'akiv (essential) for the mitzvah of hoshana. This resolves Rashi's position that stolen lulav may still permit a berachah under certain conditions.
Does adding a fifth species to the lulav violate bal tosif? The shiur distinguishes between two types of bal tosif—adding to the cheftza shel mitzvah versus performing two complete ma'aseh mitzvahs—and develops Rabbeinu Chananel's approach that the Gemara's discussion concerns whether one fulfills the mitzvah, not whether one transgresses bal tosif.
When does adding a fifth species to the four minim constitute bal tosef? The shiur analyzes the fundamental dispute among Tosafot, Rabbeinu Chananel, and the Rambam regarding whether bal tosef creates an issur, a psul, or both, and whether the principle of halachuda koi v'halachuda koi eliminates bal tosef entirely or only affects the status of the kol hamosef gorei'a.
Does a hadas that becomes pasul before Yom Tov and then becomes kosher on Yom Tov have the status of dichui? The shiur analyzes Rashi's position that dichui applies only when the lulav was tied in an agudah, suggesting that agudah creates a special status even according to those who hold lulav ein tzarich agudah. A parallel analysis examines Rashi's approach to kisui hadam and the principle of ein dichui etzel mitzvos.
Why is there a meira (flaw) when a slave, woman, or minor leads you in a mitzvah you know? The shiur analyzes the Rashi-Tosfos debate: Rashi holds the problem is appearing like you don't know (lo lamad), while Tosfos distinguishes between shomea k'oneh through a gadol (which counts as speech) versus a katon (which remains mere listening), making it a lesser kium.
Is shomea k'oneh fulfilled by hearing another's blessing, or by that person saying the blessing on your behalf? The Rambam and Tur present fundamentally opposite models: the Rambam holds you create a context for the listener's own amen-blessing, while the Tur holds the listener is fulfilled by hearing the speaker's blessing itself. This dispute reshapes the entire halacha of when amen is required and who must have intention.
When should the bracha on lulav be recited, and should it be "al" or "li"? The shiur develops the Rambam's position that the act of taking the lulav is itself part of the mitzvah, and that there is an issur to perform a mitzvah without a bracha. This leads to a fundamental difference from Tosafos and other Rishonim, explaining why various proposed solutions (holding upside down, kavana farkert) fail according to the Rambam.
Why must we make a berachah when seeing others' Chanukah candles, and why such concern for public perception in this mitzvah? The Greeks targeted Jewish communal identity itself, forcing individuals to declare 'we have no portion in the God of Israel.' Chanukah corrects this by requiring positive communal statements through public lighting that strengthens our bonds as a Torah community.
