Pesachim 4:2 - 4:3

המוליך פירות שביעית ממקום שכלו – to a beast from the field and the people of his place are liable to remove it from the house. And they bring this to a place where they had not yet come to an end, and the people of that place are still eating them from that which were brought into the house, and they are liable to remove them because of the stringencies of the place from which they left.

רבי יהודה אומר אומרים לו צא והבא לך אף אתה – There is a dispute between Rabbi Yehuda and the First Teacher [of the Mishnah] (Pesahim 52a) where one pickles/preserves three kinds of greens in vinegar or in brine to preserve and two of them came to an end for the beast from the field and the third had not yet come to an end. The First Tanna holds that one eats from those which had come to an end with the support of that which had not yet come to an end, since they are in one barrel. And this is astonishing for this thing, from a place where they did not come to an end to a place where they completely came to an end, one is obligated to remove them. But, if all of them did not come to an end, but part of them, one can eat even from the species that had come to an end all the while that all of them had not coe to an end. And one eats on support of the final ones. But Rabbi Yehuda states: We say to him: Go and bring some for yourself – even you, from that species that was completed, like this person brought and it would not be found. Therefore, one does not eat other than from the species that has not yet completed, for we don’t eat from those species that were completed through the support of the species that was not yet completed. And one is obligated to remove those species that were completed. And the Halakha is according to Rabbi Yehuda that refers to the approach of Rabban Gamaliel where the Halakha is according to him in the Tractate Sheviit (chapter 9), the “Chapter of Rue.”

מקום שנהגו שלא למכור – since they were stringent upon themselves perhaps they would come to see a large [animal].

ובכל מקום אין מוכרים להם בהמה גסה – since the Rabbis made a decree lest a person lend out or rent his animal to idolaters, and a person is commanded on resting of his animal. Alternatively, sometimes that he sells it on the eve of the Sabbath (i.e., Friday) at dusk and the Jew cries to it (i.e., the animal) in order that it should go before the purchaser and she reis animal on Shabbat recognizes his (i.e., the former owner’s) voice and she goes from his anger, and it is found that he directs a laden beast’s motions by walking behind it on Shabbat.

עגלים וסייחין – small, even though they are not doing work, they are exchanged through the sale of larger animals and broken animals are exchanged with the sale of whole animals.

רבי יהודה מתיר בשבורה – that is never capable of working ever. But calves and foals, he admits, that since when they grow, they are capable of working. But the Halakha is not according to Rabbi Yehuda.

בן בתירא מתיר בסוס – since it stands for riding and the living carries itself, but the Halakha is not according to Ben Beteyra. But via middleman, it is permitted to sell it to an idolater when the owners are not found there at the time of the sale, for one should not suspect lest he lend it out or rent it for it is not his. And lest she should go on the strength of his voice and he is found that he directs a laden beast’s motions for that also, one should not suspect, for she doesn’t recognize his voice.
