Pesachim 115a: Hasava Requirements and Hillel's Korech

Full Summary

This shiur begins with a hazara (review) of the din hasava according to the Rama, establishing that hasava is a din in seuda (requirement in the meal context) rather than an integral part of each specific mitzvah (מצוה). The Rama holds that one needs a proper seuda consisting of arba kosos of wine and a kezayis of matzah - not necessarily the first kezayis from the mitzvah itself. This differs from the Chayei Adam's interpretation that hasava must accompany the actual mitzvah performance. The discussion explores why certain Rishonim (Rash, Mordechai, Tosafos (תוספות) Rabbeinu Peretz, possibly Ramban (רמב"ן)) require going back to repeat the mitzvah if hasava wasn't performed, raising fundamental questions about how Chachamim can define deoraisa obligations and why some people are exempt from hasava entirely. The main focus then shifts to Pesachim 115a and Hillel's statement that one should not eat matzah and maror together because the mitzvah derabanan of maror is mevatal (nullifies) the taste of matzah deoraisa, preventing proper fulfillment of the matzah obligation. This raises several difficulties: why taste should matter when one can fulfill matzah by swallowing, why people without taste buds can still be obligated, and most critically, why the rabbinic status of maror creates this problem when both being mitzvot should make it acceptable. The Gemara (גמרא) presents a fundamental machloket between Hillel and the Rabanan regarding mitzvot ein mevatalot zu et zu (mitzvot do not nullify each other). Hillel holds they don't nullify each other and therefore ate them together, learning from the pasuk "al matzot u'merorim yochluhu." The Rabanan disagree, leading to the principle that nowadays we eat them separately and then do korech as a zecher lemikdash kehillel (remembrance of the Temple according to Hillel's practice). The analysis reveals tensions in understanding what exactly Hillel required - whether eating together was mandatory, optional, or preferred - and how this relates to the current practice. The Rambam (רמב"ם)'s position seems to favor eating them together while allowing separate consumption with appropriate brachot. The shiur concludes with a theoretical exploration of whether the concept of mitzvot ein mevatalot zu et zu might mean that when eating mitzvot together, one achieves both individual mitzvah fulfillment and an additional combined taste experience that the Torah (תורה) specifically desired, rather than simply avoiding nullification of separate obligations.
