מִי שֶׁיָּצָא מֵעֶרֶב שַׁבָּת חוּץ לַמְּדִינָה וְעָמַד בְּמָקוֹם יָדוּעַ בְּתוֹךְ הַתְּחוּם אוֹ בְּסוֹפוֹ וְאָמַר שְׁבִיתָתִי בְּמָקוֹם זֶה וְחָזַר לְעִירוֹ וְלָן שָׁם. יֵשׁ לוֹ לְהַלֵּךְ לְמָחָר מֵאוֹתוֹ מָקוֹם אַלְפַּיִם אַמָּה לְכָל רוּחַ. וְזֶה הוּא עִקַּר עֵרוּבֵי תְּחוּמִין לְעָרֵב בְּרַגְלָיו. וְלֹא אָמְרוּ לְעָרֵב בְּהַנָּחַת מְזוֹן שְׁתֵּי סְעֻדּוֹת בִּלְבַד בַּמָּקוֹם אַף עַל פִּי שֶׁלֹּא יָצָא וְלֹא עָמַד שָׁם אֶלָּא לְהָקֵל עַל הֶעָשִׁיר שֶׁלֹּא יֵצֵא אֶלָּא יִשְׁלַח עֵרוּבוֹ בְּיַד אַחֵר וְיַנִּיחוּ לוֹ:
When a person left his city on Friday and stood in a specific place within the Sabbath limits, or at the end of the Sabbath limits, and said, "This is my place for the Sabbath," although he returns to his city and spends the night there, on the following day he is permitted to walk two thousand cubits from that place in every direction. This is the principal manner [of establishing] an eruv t'chumin - actually to go there by foot. [The Sages allowed] one to establish an eruv by depositing an amount of food sufficient for two meals in the place - although one did not actually go there and stand there - to expedite matters for a rich person, so that he will not have to travel by himself, and could instead send his eruv with an agent who will deposit it for him.
