[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.
