מַשְׁאֶלֶת אִשָּׁה לַחֲבֶרְתָּהּ הַחֲשׁוּדָה עַל הַשְּׁבִיעִית נָפָה וּכְבָרָה וְרֵחַיִם וְתַנּוּר. אֲבָל לֹא תָבוֹר וְלֹא תִטְחַן עִמָּהּ. אֵשֶׁת חָבֵר מַשְׁאֶלֶת לְאֵשֶׁת עַם הָאָרֶץ נָפָה וּכְבָרָה, וּבוֹרֶרֶת וְטוֹחֶנֶת וּמַרְקֶדֶת עִמָּהּ. אֲבָל מִשֶּׁתַּטִּיל הַמַּיִם, לֹא תִגַּע אֶצְלָהּ, שֶׁאֵין מַחְזִיקִין יְדֵי עוֹבְרֵי עֲבֵרָה. וְכֻלָּן לֹא אָמְרוּ אֶלָּא מִפְּנֵי דַרְכֵי שָׁלוֹם. וּמַחֲזִיקִין יְדֵי נָכְרִים בַּשְּׁבִיעִית, אֲבָל לֹא יְדֵי יִשְׂרָאֵל. וְשׁוֹאֲלִין בִּשְׁלוֹמָן, מִפְּנֵי דַרְכֵי שָׁלוֹם:
A woman may lend to her fellow who is suspected in the matter of the Sabbatical year a sieve, a sifter, millstones and an oven. But she may not sort or grind with her. The wife of a <i>Chaver</i> [status marking those who scrupulously observe tithes and purity laws] may lend to the wife of an <i>Am HaAretz</i> [status marking those who are lax in observing tithes and purity laws] a sieve and a sifter, and may sort, grind and sift with her. But once she wets [the flour], she may not touch it, as one may not assist transgressors. And all of these were said only for the sake of peace. And we encourage the work of non-Jews in the Sabbatical year, but not that of Jews. And we inquire after their [the non-Jews] well-being, for the sake of peace.
