מוֹתַר שְׁיָרֵי הַלִּשְׁכָּה מֶה הָיוּ עוֹשִׂין בָּהֶן, לוֹקְחִין בָּהֶן יֵינוֹת, שְׁמָנִים וּסְלָתוֹת, וְהַשָּׂכָר לַהֶקְדֵּשׁ, דִּבְרֵי רַבִּי יִשְׁמָעֵאל. רַבִּי עֲקִיבָא אוֹמֵר, אֵין מִשְׂתַּכְּרִין מִשֶּׁל הֶקְדֵּשׁ וְלֹא מִשֶּׁל עֲנִיִּים:
The surplus of the left-overs of the lishkah [i.e., what is left over after the city needs have been satisfied] — What is done with it? Wine, oil, and meal is bought for it [and sold to those who need them for meal-offerings], and the profit goes to hekdesh. These are the words of R. Yishmael. R. Akiva says: One does not trade in hekdesh, [(for "there is no poverty in the place of wealth"; such trade is demeaning to hekdesh)], nor with what is designated for the poor, [lest a poor man come and there be nothing (on hand) to give him. The halachah is in accordance with Abba Shaul.]
