Comentário sobre Baba Metzia 3:8
יוֹצִיא לוֹ שְׁתוּת לְיַיִן. רַבִּי יְהוּדָה אוֹמֵר, חֹמֶשׁ. יוֹצִיא לוֹ שְׁלשֶׁת לֻגִּין שֶׁמֶן לְמֵאָה, לֹג וּמֶחֱצָה שְׁמָרִים, לֹג וּמֶחֱצָה בָּלַע. אִם הָיָה שֶׁמֶן מְזֻקָּק, אֵינוֹ מוֹצִיא לוֹ שְׁמָרִים. אִם הָיוּ קַנְקַנִּים יְשָׁנִים, אֵינוֹ מוֹצִיא לוֹ בָּלַע. רַבִּי יְהוּדָה אוֹמֵר, אַף הַמּוֹכֵר שֶׁמֶן מְזֻקָּק לַחֲבֵרוֹ כָּל יְמוֹת הַשָּׁנָה, הֲרֵי זֶה מְקַבֵּל עָלָיו לֹג וּמֶחֱצָה שְׁמָרִים לְמֵאָה:
Ele deduz um sexto para o vinho [se ele depositou vinho com ele, e ele se misturou ao seu vinho. (Os vasos absorvem um sexto.)] R. Yehudah diz: Um quinto. [Porque a terra da qual os vasos foram feitos no local de R. Yehudah absorveu um quinto; tudo de acordo com a localidade.] Ele deduz três toras de óleo a cem—um tronco e meio para borras; um tronco e meio para absorção. Se fosse óleo refinado, ele não deduz por borras. Se fossem vasos velhos, ele não deduz para absorção. R. Yehudah diz: Além disso, se alguém vende óleo refinado para o seu vizinho todos os dias do ano, ele (o comprador) aceita (uma dedução de) uma vez e meia a cem por borras. [Assim como estipularam (uma dedução para) borras para o depositante, assim como estipularam para o vendedor, a saber: se alguém vende óleo para o vizinho e o entrega de seus jarros óleo refinado que ele usa constantemente, o comprador aceita um dedução de um log e meio a cada cem para borras. A halachá não está de acordo com R. Yehudah.]
Bartenura on Mishnah Bava Metzia
English Explanation of Mishnah Bava Metzia
He may exact of him three logs in every one hundred logs of oil one log and a half for sediment and one log and a half for absorption. If the oil was refined he may not exact for sediment. If the jars were old he may not exact for absorption.
Rabbi Judah says: “Also if a man sells to his fellow through the year, the buyer must undertake to accept a reduction of one and a half logs because of sediment.
With wine and oil there are no reductions for mice, as there were with produce, but there are reductions due to sediment and absorption in the sides of the clay vessels which were used at the time. With wine the guardian may exact a reduction of one-sixth or one-fifth according to Rabbi Judah.
With regards to oil it depends on the type of jar and the type of oil. Regular oil is reduced 1½ per cent due to sediment, but refined oil does not produce any sediment and therefore reductions may not be exacted. Regulars jars absorb 1½ per cent but old jars, whose sides are more hardened and have already absorbed oil, do not absorb any oil. Therefore if the jars were old the guardian may not exact a reduction for absorption.
Rabbi Judah adds that not only may a guardian exact a reduction of 1½ per cent the oil returned to the owner, but so too may a person who sells refined oil. In other words if Reuven tells Shimon that he is selling him 100 logs of oil and then gives him refined oil, he only need give him 98 ½ logs since 1½ logs of regular oil would be worthless sediment anyway.
