Text Excerpt
אמר רבא: הלכתא חמץ בזמנו, בין במינו בין שלא במינו — אסור במשהו, כרב. שלא בזמנו, בין במינו בין שלא במינו — מותר, כרבי שמעון.
Rava said: The halakha is that with regard to the prohibition against eating a mixture of leavened bread during its time of prohibition, i.e., during Passover, regardless of whether it is mixed with its own type or with another type, it is forbidden, even if any amount becomes mixed in, in accordance with the opinion of Rav. Not during its time of prohibition, but rather after the conclusion of Passover, regardless of whether the leavened bread was mixed with its own type or with another type, it is permitted, even when it gives flavor to the mixture. This is in accordance with the opinion of R' Shimon, who states that leavened bread owned by a Jew during Passover is permitted after Passover.
ומי אמר רבא הכי? והאמר רבא: רבי שמעון קנסא קניס, הואיל ועבר עליו ב״בל יראה״ ו״בל ימצא״!
The Talmud asks: Did Rava actually say this, that according to R' Shimon, leavened bread owned by a Jew on Passover is permitted after Passover? But didn’t Rava himself say that R' Shimon imposed a penalty forbidding one from deriving benefit from leavened bread owned by a Jew during Passover, since he transgressed the prohibition it should not be seen and the prohibition it should not be found?
הני מילי בעיניה, אבל על ידי תערובת — לא. ואזדא רבא לטעמיה, דאמר רבא: כי הוינן בי רב נחמן, כי הוו נפקי שבעה יומי דפסחא אמר לן: פוקו וזבינו חמירא דבני חילא.
The Talmud resolves this challenge: This penalty applies only to leavened bread that is in its pure unadulterated form, but with regard to a mixture, no, one does not impose a penalty, even though the leavened bread is still extant. The Talmud adds: And Rava follows his line of reasoning, stated elsewhere, that indicates that he rules in accordance with the opinion of R' Shimon, as Rava said: While we were studying in Rav Naḥman’s house, on the evening when the 7 days of Passover had passed, he said to us: Go and buy leavened bread from the non-Jews who baked it on that day, the last day of Passover. Based on this story, it is clear that he maintained that one may eat leavened bread that was owned by a non-Jew during Passover.
