The evening of the fourteenth [of Nissan] we must search for the chametz by the light of a candle. Any place into which chametz is not brought does not require a search.  So why have the Sages said, “Two rows of a [wine] cellar [must be searched]?” [The Sages were referring to] a place into which chametz. is brought.  Beis Shammai say: Two rows over the entire front of the [wine] cellar [must be searched]; but Beis Hillel say: The two outer rows which are the uppermost.

We need not be concerned that a weasel may have dragged [chametz] from house to house or from place to place, for if so, [then we would have to be concerned] from courtyard to courtyard and from town to town, and there would be no end to the matter.

R' Yehudah says: We must search on the evening of the fourteenth, or on the morning of the fourteenth, or at the time of removal.  But the Sages say: If one did not search on the evening of the fourteenth, he must search on the [day of the] fourteenth; if he did not search on the [day of the] fourteenth, he must search during the festival; if he did not search during the festival, he must search after the festival.  That which he leaves over, he should place in hiding, so that it not be necessary to search for it [again].

R' Meir says: We may eat [chametz] the entire fifth [hour], and we must burn [it] at the onset of the sixth [hour].  But R' Yehudah says: We may eat [chametz] the entire fourth [hour], but we suspend [it] the entire fifth [hour], and we must burn it at the onset of the sixth [hour].

R' Yehudah also said: Two loaves of a thanksgiving-offering [which had become] unfit were placed on the roof of the portico. As long as they lay [there] all the people would eat [chametz]. [When] one was removed, they suspended: — they would neither eat nor burn [the chametz]. When both were removed, all the people would begin to burn [their chametz].  Rabban Gamliel says: Nonconsecrated [chametz] may be eaten the entire fourth [hour]; terumah [which is chametz may be eaten] the entire fifth [hour]; and we must burn [all chametz] at the onset of the sixth [hour].

R' Chanina, administrator of the Kohanim, says: In all the days of the Kohanim, never did they refrain from burning [sacrificial] meat that had been contaminated by a secondary tumah together with [sacrificial] meat that had been contaminated by a primary tumah, although [by so doing] they added contamination to its contamination.  R' Akiva added, saying: In all the days of the Kohanim, never did they refrain from lighting oil that had become unfit [through contact] with a t'vul yom in a lamp that had been contaminated by one contaminated by a corpse, although [by so doing] they added contamination to its contamination.

R' Meir said: From their words we infer that we may burn uncontaminated terumah [which is chametz] with contaminated terumah on Pesach.  R' Yose said to him: This is not analogous. [Even] R' Eliezer and R' Yehoshua concur that each is burned separately. Concerning what do they differ? — Concerning suspended and contaminated [terumah], where R' Eliezer says that each must be burned separately, but R' Yehoshua says that both [may be burned] together.

As long as it is permitted to eat [chametz], one may feed [it] to livestock, beasts, and birds, and sell it to a Gentile, and [deriving] benefit from it is permitted. When its period has passed, [deriving] benefit from it is forbidden, and one may not fire an oven or a range with it.  R' Yehudah says: There is no removal of chametz except by burning. But the Sages say: He may also crumble [it] and throw [it] to the wind or cast [it] into the sea.

Chametz of a Gentile over which Pesach has passed, [deriving] benefit from it is permitted; but [chametz] of a Jew, [deriving] benefit from it is forbidden —- since it is said: Nor shall leaven be seen with you (Exodus 13:7).

[If] a Gentile lent [money] to a Jew on his chametz, [then] after Pesach [deriving] benefit from it is permitted. But [if] a Jew lent [money] to a Gentile on his chametz, [then] after Pesach [deriving] benefit from it is forbidden.  [If] a ruin collapsed over chametz, it is regarded as removed. Rabban Gamliel says: Provided a dog cannot search it out.

One who eats terumah of chametz on Pesach, inadvertently, must repay [a Kohen] the principal plus a fifth; if [he eats it] deliberately, he is free from payment and from [liability for] its value as fuel.

These are the species [of grain] with which a man fulfills his obligation [of matzah] on Pesach: with wheat, barley, spelt, rye, and oats. And we can discharge it with demai, with first tithe whose terumah has been separated, and with second tithe or consecrated produce that were redeemed; Kohanim —- with challah and with terumah; but not with untithed produce, nor with first tithe whose terumah has not been separated, nor with second tithe or consecrated produce that were not redeemed.  [Regarding] the [unleavened] loaves of the thanksgiving-offering, and the nazirite's wafers: — [If] he made them for himself, he cannot fulfill his obligation with them; [but if] he made them to sell in the market, he can fulfill his obligation with them.

If a sheretz was found in the Temple, a Kohen may remove it with his sash, so as not to prolong the presence of the tumah-contamination — [these are] the words of R’ Yochanan ben Berokah. R’ Yehudah says: With wooden tongs, so as not to increase the contamination. From where do we remove it? From the Temple, the Antechamber, and be-tween the Antechamber and the Altar — [these are] the words of R’ Shimon ben Nanas. R’ Akiva says: The area for which one incurs kares for an intentional transgression and a sin offering for unintentional transgression — from there we must remove it; but all other areas, we cover it with a pot. R’ Shimon says: Wherever the Sages have granted a dispensation, they have given you what is yours, for they have not permitted except that which is a Rabbinical decree.
