Pesachim No.1: This American Light

MISHNA: On the evening [or] of the fourteenth of the month of Nisan, one searches for leavened bread in his home by candlelight. Any place into which one does not typically take leavened bread does not require a search, as it is unlikely that there is any leavened bread there. And with regard to what the Sages of previous generations meant when they said that one must search two rows of wine barrels in a cellar, i.e., a place into which one typically takes some leavened bread, the early tanna’im are in dispute. Beit Shammai say that this is referring to searching the first two rows across the entire cellar, and Beit Hillel say: There is no need to search that extensively, as it is sufficient to search the two external rows, which are the upper ones. This dispute will be explained and illustrated in the Gemara.

The Gemara suggests: Come and hear a resolution to this dilemma, as Abaye said: Needless to say, that in a place where people typically do not pay a wage and hire others to conduct the search for leaven and everyone searches himself, a person prefers to fulfill the mitzva himself. However, even in a place where people pay a wage and have others search for leaven, it is not a mistaken transaction due to the fact that a person prefers to perform the mitzva with his own money. Consequently, it is not considered a mistaken transaction, as a person does not object to having to perform a mitzva.

Come and hear another proof, as it was taught in the school of Shmuel: On the evening of the fourteenth of Nisan, one searches for leavened bread by candlelight. Apparently, or is evening, as this baraita replaces or with the word evening.

It is clear from these proofs that the expression or in the mishna means the evening before the day. How, then, could the amora’im dispute whether it is referring to the morning or evening? Rather, the Gemara rejects its previous assumption with regard to the dispute, as everyone, both Rav Huna and Rav Yehuda, agrees that or is evening, and they do not disagree with regard to the halakha. However, this Master stated the halakha in accordance with the expression accepted in his place, and that Master stated the halakha in accordance with the expression accepted in his place. In Rav Huna’s place, they call the evening light, and in Rav Yehuda’s place they call it night, although both terms refer to the same period.
