Pesachim 6b: Bal Yeira'eh, Bal Yimatzei, and Bittul Chametz Part 2

Full Summary

This shiur provides an intensive analysis of Pesachim 6b, focusing on the complex issue of bittul chametz (nullification of chametz) and its relationship to the biblical prohibitions of bal yeira'eh and bal yimatzei. Rabbi Zweig begins by examining a fundamental problem in Rashi (רש"י)'s commentary regarding the structure and logic of his explanation of bittul. The Gemara (גמרא) establishes that one who searches for chametz must nullify it (habodek tzarich sh'vitulo), but Rashi's explanation seems internally contradictory - he begins discussing when bittul must be done (immediately after bedika) but then shifts to describing what bittul is (saying 'kol chamir d'ika b'veit ha-din libatel'). Rabbi Zweig questions why Rashi doesn't present these concepts in a more logical order. The shiur then delves into the Gemara's concern about finding a 'glus ki yafa' (a nice loaf) during Yom Tov. The problem is that if someone finds valuable chametz, they may be reluctant to burn it (chas v'shalei l'sorfo), and during that hesitation, they would violate bal yeira'eh and bal yimatzei. The Gemara asks why not simply nullify the chametz when it's found, leading to the response that after zman issur (the time of prohibition), bittul is no longer effective. Rabbi Zweig extensively analyzes different approaches to understanding bittul. He contrasts Rashi's view that bittul means considering the chametz 'like dirt' (k'afra) with Tosafos (תוספות)'s position that bittul renders the chametz hefker (ownerless). This distinction has practical implications: according to Tosafos, if chametz becomes hefker through bittul, finding it later doesn't create a violation since it's not owned. According to Rashi, even after bittul, the psychological reluctance to destroy valuable chametz could still create a momentary violation. A significant portion of the shiur addresses whether bittul is permanent or temporary. Rabbi Zweig explores whether making chametz 'like dirt' means forever or just for the duration of Pesach (פסח). He draws analogies to other areas of halacha (הלכה), such as using items to raise the floor of a sukkah, where bittul may be temporary. This analysis helps explain why someone might be able to nullify chametz while still being reluctant to physically destroy it. The shiur examines the two-fold nature of bittul in Rashi's system. Rabbi Zweig suggests that Rashi may distinguish between bittul b'lev (nullification in the heart), which must be done immediately and addresses the bal yeira'eh/bal yimatzei prohibitions, and the verbal declaration of bittul, which addresses the positive commandment of tashbisu (you shall remove). This explains why Rashi presents the timing requirement separately from the content requirement. Rabbi Zweig brings support from the Ran's citation of a midrash on lo yeira'eh lecha, suggesting that bittul involves severing one's connection to the chametz rather than physical destruction. He also references another midrash on tashbisu, indicating that the positive commandment can be fulfilled through bittul rather than only through physical burning. The analysis concludes by suggesting that Rashi's seemingly disjointed explanation actually reflects two distinct aspects of bittul: one that removes the prohibition aspect (accomplished immediately through mental nullification) and another that fulfills the positive commandment (accomplished through verbal declaration, which need not be immediate). This sophisticated reading resolves the apparent inconsistencies in Rashi's commentary while maintaining the logical structure of the halachic requirements.
