Pesachim 6a: Covering Chametz with a Vessel - Muktzeh vs. Prevention

Full Summary

This shiur provides an in-depth analysis of Gemara (גמרא) Pesachim 6a, focusing on the complex issue of covering chametz with a vessel (kofal alav kli) on Yom Tov. The discussion begins with examining Rashi (רש"י)'s position that if chametz is not in one's house, there is no violation of bal yeraeh u'bal yimatzei (the prohibition against seeing and finding chametz on Pesach (פסח)). However, the practical question arises: why can't one simply remove such chametz? The answer lies in the laws of muktzeh - objects forbidden to be moved on Shabbat and Yom Tov. The Gemara presents a fundamental dispute between Rashi and Tosafot regarding the permissibility of covering chametz with a vessel. According to Rashi, this action is problematic because it violates the principle of ein kli nittal ela l'tzorech (a vessel may not be moved except for its intended use). When one covers muktzeh chametz, the vessel itself becomes muktzeh, as it is being used to serve something forbidden to handle. Tosafot offers two approaches (teratzim) to resolve this difficulty. The first approach suggests that covering the chametz is not merely to prevent oneself from eating it, but rather constitutes an act of designation for destruction (miyached l'srefah). This designation removes the dil ma oseh l'mochlo (concern that one might come to eat it) because the chametz has been set aside specifically for burning. Once designated for destruction, there is no longer the same concern about accidentally consuming it. The second approach in Tosafot distinguishes between actions done for the sake of the forbidden object versus actions done for one's own protection. Covering chametz is not serving the chametz itself, but rather creating a barrier to prevent oneself from transgressing. This is analogous to putting a muzzle on oneself rather than protecting the forbidden item. The discussion extends to examining when chametz found on Pesach requires bitul (nullification). Rashi holds that even chametz one intends to burn still violates bal yeraeh u'bal yimatzei unless it was previously nullified. Tosafot disagrees, maintaining that chametz designated for burning does not create this violation. The shiur also explores the concept of hefker (abandonment) and its relationship to bitul. The Gemara discusses cases where items are considered 'lo chasid' (not valuable), such as inferior dates (suftei tmarim), which people generally don't bother to collect. Such items may be considered hefker, thereby removing the obligation for bitul since they are no longer considered one's property. Rashi's commentary emphasizes the requirement for verbal declaration (amirah) in bitul, not merely mental intention. This reflects his understanding that bitul must be an active process of renunciation rather than passive disregard. The practical implications affect how one must approach the mitzvah (מצוה) of removing chametz and the proper procedure for nullification. The analysis concludes by examining how these principles apply to chametz belonging to a non-Jew (chametz shel nochri) found in one's house, where different considerations apply since there is no obligation to destroy what belongs to others.
