משנה: אַנְשֵׁי עִיר גְּדוֹלָה מְהַלְּכִין אֶת כָּל עִיר קְטַנָּה. וְאַנְשֵׁי עִיר קְטַנָּה מְהַלְּכִין אֶת כָּל עִיר גְּדוֹלָה. כֵּיצַד מִי שֶׁהָיָה בְעִיר גְּדוֹלָה וְנָתַן אֶת עֵירוּבוֹ בְעִיר קְטַנָּה. אוֹ בְעִיר קְטַנָּה וְנָתַן אֶת עֵירוּבוֹ בְעִיר גְּדוֹלָה מְהַלֵּךְ אֶת כּוּלָּהּ וְחוּצָה לָהּ אַלְפַּיִם אַמָּה. רִבִּי עֲקִיבָה אוֹמֵר אֵין לוֹ מִמְּקוֹם עֵירוּבוֹ אֶלָּא אַלְפַּיִם אַמָּה:
MISHNAH: The people of a large town walk through all of a small town; the people of a small town walk through all of a large town. How is that? If somebody lived in a large town and put his eruv in a small town, or in a small town and put his eruv in a large town, he walks through all of it and outside of it 2’000 cubits. But Rebbi Aqiba says, he only has 2’000 cubits from the place of his eruv.
