אַחַת לִשְׁלשִׁים יוֹם, מְשַׁעֲרִין אֶת הַלִּשְׁכָּה. כָּל הַמְקַבֵּל עָלָיו לְסַפֵּק סְלָתוֹת מֵאַרְבַּע, עָמְדוּ מִשָּׁלשׁ, יְסַפֵּק מֵאַרְבַּע. מִשָּׁלשׁ וְעָמְדוּ מֵאַרְבַּע, יְסַפֵּק מֵאַרְבַּע, שֶׁיַּד הֶקְדֵּשׁ עַל הָעֶלְיוֹנָה. וְאִם הִתְלִיעָה סֹלֶת, הִתְלִיעָה לוֹ. וְאִם הֶחְמִיץ יַיִן, הֶחְמִיץ לוֹ. וְאֵינוֹ מְקַבֵּל אֶת מְעוֹתָיו, עַד שֶׁיְּהֵא הַמִּזְבֵּחַ מְרַצֶּה:
Once every thirty days, the market price is established for the lishkah. [The price is established for wine, oil, and flour, to stand for thirty days. And they (the Temple buyers) buy what they need every day from the sellers of wine, oil, and meal for the stipulated sum. If the price rises, they do not give more, and if it falls, they give less.] All who take upon themselves to supply meal at four — if it stood at three, they must supply at four. If (they take upon themselves to supply flour) at three, and it stood at four, they must supply at four. For hekdesh always has the upper hand. [In the days of the grain, wine, and olive harvest, the treasurers would advance money to the merchant, who would take it upon himself to supply wine, oil, and flour for the entire year. And if at that time the market price were four sa'ah for a sela and it rose to three sa'ah for a sela, he must give it at four sa'ah for a sela. For hekdesh acquires (the purchase) with money, viz. (as per Leviticus 27:19): "And he shall give the money and it shall be his." And if he undertook to supply three sa'ah for a sela and the price fell to four sa'ah for a sela, he gives four sa'ah for a sela. For hekdesh is not inferior in this regard to hedyot (non-hekdesh), which acquires only at (the time of) meshichah ("drawing forth" the purchased object)]. And if the meal became wormy, it became wormy for him (the supplier). [Even if the Temple treasurer effected meshichah and paid for it, the responsibility is the merchant's.] And if the wine turned sour, it turned sour for him. And he does not receive his money until it (the meal or the wine) is accepted upon the altar. [Therefore, if the wine turns sour or the flour becomes wormy, the responsibility is the merchant's.]
