23אֶחָד אוֹ רַבִּים שֶׁאָמְרוּ לְאֶחָד צֵא וַעֲרֵב עָלֵינוּ וְעֵרֵב עֲלֵיהֶן בְּאֵי זֶה רוּחַ שֶׁרָצָה הֲרֵי זֶה עֵרוּב וְיוֹצְאִין בּוֹ שֶׁהֲרֵי לֹא יִחֲדוּ לוֹ רוּחַ. הָאוֹמֵר לַחֲבֵרוֹ עָרֵב עָלַי בִּתְמָרִים וְעֵרֵב עָלָיו בִּגְרוֹגָרוֹת. בִּגְרוֹגָרוֹת וְעֵרֵב עָלָיו בִּתְמָרִים. אָמַר לוֹ הַנִּיחַ עֵרוּבִי בְּמִגְדָּל וְהִנִּיחוֹ בְּשׁוֹבָךְ. בְּשׁוֹבָךְ וְהִנִּיחוֹ בְּמִגְדָּל. בַּבַּיִת וְהִנִּיחוֹ בַּעֲלִיָּה בַּעֲלִיָּה וְהִנִּיחוֹ בַּבַּיִת אֵינוֹ עֵרוּב. אֲבָל אִם אָמַר לוֹ עָרֵב עָלַי סְתָם וְעֵרֵב עָלָיו בֵּין בִּגְרוֹגָרוֹת בֵּין בִּתְמָרִים בֵּין בַּבַּיִת בֵּין בַּעֲלִיָּה הֲרֵי זֶה עֵרוּב:
When one person or a group of people tell another person, "Go out and make an eruv on our behalf," and the person does so, choosing the direction in which to make the eruv himself, the eruv is acceptable. They may rely on it, for they did not specify the direction [they desired]. When a person says, "Establish an eruv for me with dates," and [his agent] establishes with dried figs, or he mentions dried figs, and [the agent] uses dates, the eruv is not acceptable. Similarly, if the person asked that the eruv be placed in a closet and it was placed in a dovecote, or [he asked that it be placed] in a dovecote, and it was placed in a closet, or [he asked that it be placed] in a house, and it was placed in a loft, or [he asked that it be placed] in a loft, and it was placed in a house, the eruv is not acceptable. If, however, the person told [the agent], "Establish an eruv for me," without making any specifications, the eruv is acceptable regardless of whether he used dried figs or dates, or deposited it in a house or in a loft.
