The landowner may not separate terumah from tithes and [thereafter] obtain permission from the Levite, nor [take] the shankbone, the jawbone or the rough-stomach [of an animal, see Deut. 18:3] and [thereafter] obtain permission from the Kohen, but he may make them a loan in order for it to count [as terumah or priestly gifts, see Gitt. 3:8]

[If] he had in his heart (i.e., he intended) to take terumah of wine on behalf of wine, but what he had in his hand was vinegar, his terumah is not [valid] terumah. If he had wine in his hand, he takes terumah from the wine, and he goes back and takes terumah from the vinegar. If he had checked the barrel in order to separate [terumah] on its behalf, and then he returns and finds it has turned to vinegar: [If] three days or less [had transpired between the first and second check], it is [considered] certainly untithed produce, and from [three days and up] there is a doubt. But [as to] wine from a vat we may separate terumah on its behalf with the presumption that it remains wine for up to 40 days.

A Yisrael [may] separate [tithes] -- whether with the permission of the Levite or the permission of the poor -- and account for it at the end, the words of Rabbi Meier. [And] Rabbi Yehudah and Rabbi Yosei and Rabbi Shimon forbid it, but if [he does it anyways] he gives [the Levite or the poor person] an [additional] tenth.
