62 Pesachim/3-6

(3) If a gentile lent money to an Israelite upon [the security] of [the latter's] chamets [and he defaults on the loan], it is permitted to benefit from it after Pesach; but when an Israelite has lent money to a gentile upon [the security] of [the latter's] chamets [and he defaults on the loan], it is forbidden to benefit from it after Pesach; If chamets has been covered by fallen ruins, behold it is as if it is destroyed; Rabban Shimon ben Gamliel says, "Only when [it is so covered that] a dog cannot search for it."

(4) [A common Israelite] who eats terumah [a portion of a crop given to a Kohen which becomes holy upon separation, and can only be consumed by Kohanim or their household] that is chamets on Pesach, [if it be] through error, he must pay the principal, and the fifth part [in addition]; but if [he did it] willfully, he is exempt from payments, and [even of paying] for the value of the wood [if the chamets were to have been used for fuel in the place of wood].

(5) These are the [grains] with which a person may discharge his [obligation to eat matsa] on Pesach: with wheat, with barley, with spelt, and with rye, and with oats. We may discharge [our obligation] with demai‎ [produce from which it is uncertain whether tithes were already taken], and with ma'aser rishon [the first tithe of produce, which must be given to the Levi] from which terumah has been taken; and with ma'aser sheni [the second tithe of produce, which must be taken to Jerusalem and consumed there] and hekdesh [property, living or inanimate, devoted by its owner for sacred purposes, by which action he ceases to be its owner] which have been redeemed; and for Kohanim [members of the priestly caste, a subgroup of tribe of Levi, which is uniquely responsible for maintaining and carrying out the sacrificial services in the Temple] with challah [a portion of a batch of bread dough given to a Kohen which becomes holy upon separation, and can only be consumed by Kohanim or their household], and with terumah. But [we may] not [discharge our obligation] with tevel [produce from which the various tithes have not yet been separated]; and not with ma'aser rishon, from which terumah has not been taken; or with ma'aser sheni and hekdesh which have not been redeemed; and not with the loaves of a thank-offering, and the thin cakes of the offering of a nazir [a person who vows to avoid corpse impurity, refrain from cutting his hair and abstain from all grape products], if one had made them for his own use; if [however] he had made them to sell in the market, we may discharge [our obligation] with them.

(6) These are the vegetables with which a person discharges his [obligation to eat bitter herbs] on Pesach: with lettuce, and with wild endive, and with garden endive, and with ‏field eryngo, and with bitter coriander; we may discharge [our obligation] with them whether they are fresh or dried, but not [if they are] pickled, boiled, or cooked. [These different vegetables] may combine [together] to [make up the required size of] a kazayit [a specific measure of volume]; and we may discharge [our obligation] with their stalks; and with demai‎, and with ma'aser rishon from which terumah has been taken; and with ma'aser sheni and hekdesh which have been redeemed.
