[If] donkey-drivers entered a town, [and] one [of them] said: ‘‘My [produce] is new, but my colleagues is old. My [produce] is not fixed, but my colleagues is fixed,’’ they are not believed. R’ Yehudah says: They are believed.

[If] someone buys from a baker, how does he tithe [what he has bought]? He takes [a quantity] sufficient for terumas maaser and challah and says ‘‘One hundredth of what is here [in the entire loaf], let it be maaser [rishon] on this side, and the rest of the maaser [rishon] is next to it. This [hundredth] that I have made maaser [rishon] is made into te-rumas maaser for it, and the rest is challah; the maaser sheni is in its northern or south-ern [side], and it is deconsecrated on the coins.’’

One who wishes to separate terumah and terumas maaser at one time, takes one [part] from thirty-three and a third, and says: ‘‘One hundredth of what there is here [in the pile], which is on this side, is chullin, and the rest is terumah for the whole [pile]. The hundredth chullin that is here, which is on this side, is maaser [rishon], and the rest of the maaser [rishon] is next to it; that which I made maaser [rishon], is [now] made into terumas maaser for it, and the rest is challah. The maaser sheni is on its northern or southern [side], and is deconsecrated on the coins.’’

One who buys from a baker may tithe from hot [bread] for cold [bread], and from cold [bread] for hot, even from many forms; these are the words of R’ Meir. R’ Yehudah for-bids, for I say: The wheat of yesterday was from one [person], and that of today was from another. R’ Shimon forbids with [respect to] terumas maaser, and permits with [respect to] challah.

One who buys from a palter must tithe [separately] from each form; these are the words of R’ Meir. R’ Yehudah says: [He may tithe] from one for the whole. [But] R’ Yehu-dah concedes that if one buys from a monpol, he must tithe [separately] from each and every one.

One who buys from a pauper, and similarly, a pauper who was given pieces of bread or chunks of pressed-fig — tithes from each and every one. But with dates and dried figs — he mixes [them] and takes [maaser]. R’ Yehudah said: When is this so? When the dona-tion is large. But when the donation is small, he tithes from each and every one.

One who buys from a grain wholesaler, and then buys from him a second time, cannot tithe from this [purchase] on behalf of that [one], even [if both are] from the same con-tainer, [and] even [if both are] of the same variety. [However,] the wholesaler is believed to say, ‘‘They are from one [person].’’

One who buys from a householder, and then buys from him a second time, may tithe from this [purchase] on behalf of that [one], even [if they are] from two boxes, [and] even [if they are] from two towns. [If] a householder was selling vegetables in the market: When they bring him from his [own] gardens, [the buyer] may tithe from one [purchase] on behalf of all; [when they bring him] from other gardens, he must tithe from each and every one.

[If] someone buys tevel from two places, he may tithe from this [purchase] on behalf of that [one]. Even though they said [this, nevertheless,] a person is not permitted to sell tevel except for a need.

One may tithe from [tevel] of a Jew on behalf of [tevel] of a gentile; from [tevel] of a gentile on behalf of [tevel] of a Jew; from [tevel] of a Jew on behalf of [tevel] of a Cuthean; from [tevel] of a Cuthean on behalf of [tevel] of a Cuthean. R’ Eliezer forbids [tithing] from [tevel] of a Cuthean on behalf of [tevel] of a Cuthean.

A perforated plant-pot is like the ground. [If] one separated terumah from [produce of] the ground on behalf of [produce of] a per-forated plant-pot, or from [produce of] a perforated plant-pot on behalf of [produce of] the ground, his terumah is terumah. [If he separated terumah] from [produce of] a non-perforated [pot] on behalf of [produce of] a perforated [pot], it is terumah, but he must separate terumah again. [If he separated terumah] from [produce of] a perforated [pot] on behalf of [pro-duce of] a nonperforated [pot], it is terumah, but it may not be eaten until he takes out terumah and tithes for it.

[If] one separated terumah from demai on behalf of demai, [or] from demai on behalf of definite [tevel], it is terumah but he must separate terumah again. [If one separated terumah] from definite [tevel] on behalf of demai, it is terumah but it may not be eaten until he takes out terumah and tithes for it.

One who contracts a field [as a sharecropper] from a Jew, an idolater, or a Cuthean di-vides [the produce] in their presence. One who leases a field [as a tenant-farmer] from a Jew separates terumah and [then] gives him [his share]. R’ Yehudah said: When [is this so]? When he gave him from that [same] field and from that [same] species; but if he gave him from a different field or from a different species, he tithes and [then] gives him.

One who leases a field [as a tenant-farmer] from an idolater tithes and [then] gives him [his share]. R’ Yehudah says: Also one who sharecrops an ancestral field from an idolater tithes and [then] gives him [his share].

[If] a Kohen or Levite contracted a field [as a sharecropper] from a Yisrael, just as they divide the chullin, so do they divide the terumah. R’ Eliezer says: The tithes, too, are theirs, for it is on this condition that they came.
