תרומות ד׳:י״א - ד׳:י״ב

מגורה – a storehouse where they store the grain.

וקפאה – he removed what was above, the Aramaic translation of (II Kings 6:6): “and he made the ax head float”: the iron floated.

אם יש בקפוי תעלה באחד ומאה – The Jerusalem Talmud explains that this is what he said: if there is in the skimming with what is underneath it one-hundred and one [parts], it is neutralized, and Rabbi Eliezer, according to his reasoning, who said that he ones on the bottom neutralize the ones on the top, and it comes to tell us that even though he skimmed it, he revealed his intention that it had not become mixed with the bottom ones, nevertheless, the bottom ones assist to nullify.

ורבי יהושע אומר לא תעלה – Rabbi Yehoshua, according to his reasoning who said about that the bottom ones do not assist to nullify.

סאה תרומה וכו' – it is the conclusion of the words of Rabbi Yehoshua, and this is what he said: since it is not neutralized, how does he do it? יקפיאנה – he should remove what floats above and a bit around it until he knows that he removed everything, and all of the rest is unconsecrated produce.

אם כן למה אמרו – our Mishnah disputes the words of Rabbi Yehoshua. If so, in which place did they say that heave-offering requires one and one hundred [parts], since there is repair through skimming. And they respond that when it is not known if the Seah had become mixed up in the storehouse after it fell on the lip of the storehouse, alternatively, from the outset, it was not known where it fell, and the Halakha is according to Rabbi Yehoshua.

שתי קופות – in each one is fifty Seah [of unconsecrated produce].

ואין ידוע לאיזו מהן נפלה – and both are forbidden from doubt, they assist each other tonullify, and if he wanted to neutralize a Seah from this one, he neutralizes, from that one, he neutralizes, half from this and half from that one, he neutralizes. And these two bins, even if they are in two homes, and it is not known from into which the Seah of heave-offering fell, they neutralize each other, because it is their manner to be vacated, and they are carried from place to place and sometimes are mixed with each other. But two storehouses are not carried; when they are in the same house, they neutralize each other, and if they are in two [houses], they don’t neutralize each other.

ר"ש אומר אפילו הן שבתי עיירות – but the Halakha is not according to Rabbi Shimon.
