Terumos 3:4 - 3:5

במה דברים אמורים – that which Rabbi disputes above and states that the heave-offering of both is Terumah/heave-offering.

בשלא דבר – that this one did not receive permission from his colleague to separate the heave-offering, but rather, he separated the heave-offering of his own accord.

אבל הרשה – that the owner gave permission [to his colleague] to separate the heave-offering, his heave-offering is a heave-offering.

בטל – if afer he had appointed an agent to separate the heave-offering, he cancelled his agency after the agent went from before him.

חוץ – the owners who are illiterate who hired workers who are members of the order for the observance of Levitical laws in daily intercourse in order to separate the heave-offering in ritual purity, are permitted to separate the heave offering until the illiterate owners arrived who would defile the heave-offering, because they ritually defile the vat for wine pressing, for the illiterate owners immediately when the when those who tread began to stamp and they went to the vat for wine pressing in the longitudinal and latitudinal directions are not more careful from coming into contact in their vas for wine-pressing and defile it, because they think that immediately when they begin to tread, their colleagues had separated out the Great Terumah/heave-offering (i.e., two percent for the Kohen). Therefore, they separate the members of the order for the observance of Levitical laws in daily intercourse that stamp from the wine in order [to reach] the measure of heave-offering that is necessary for the vat for wine-pressing immediately when they walked in it longitudinally and latitudinally. If the owners would come and defile the vat for wine pressing prior to their completing it, they have designated wine to separate everything in ritual purity.

קרא שם – and he must separate the heave-offering and to tithe from within it., but he is not able to separate [tithes] from another place. And even though the All-Merciful called the Terumah/heave offering "ראשית"/”the first” and we require that its remnants are recognized, for since he said, “within it,” it implies, in the middle of the pile will be the heave-offering, but there is surrounding it which is its remnants that are recognized.

עד שיאמר בצפונו או בדרומו – even though “within it” implies in its middle, it is not a specific place, and it is as if he did not say anything until he would say, in its northern portion or in its southern portion, and this is the Halakha.

תרומת הכרי ממנו עליו קרא שם – and we don’t require its remnants being recognized.

עשור מעשר זה וכו' – Rabbi Eliezer ben Yaakov disputes on Rabbi Shimon who stated that this Terumah of the tithe (which the Levite to a Kohen) is within the pile that he validly designated, but after the tithe is separated, if he stated that the Terumah of the tithe is for it, he has validly designated it. But the Halakha is not like any of them, other than the Sages alone.
