משנה: הָאַחִין הַשּׁוּתָפִין שֶׁהָיוּ אוֹכְלִין עַל שׁוּלְחַן אֲבִיהֶן וִישֵׁינִין בְּבָתֵּיהֶן צְרִיכִין עֵירוּב לְכָל אֶחָד וְאֶחָד. לְפִיכָךְ אִם שָׁכַח אֶחָד מֵהֶן וְלֹא עֵירֵב בִּיטֵּל רְשׁוּתוֹ. אֵימָתַי בִּזְמַן שֶׁמּוֹלִיכִין אֶת עֵירוּבָן לְמָקוֹם אֶחָד אֲבָל אִם הָיָה עֵירוּב בָּא אֶצְלָן אוֹ שֶׁאֵין עִמָּהֶן דִּיוּרִין בֶּחָצֵר אֵינָן צְרִיכִין לְעָרֵב:
MISHNAH: Brothers sharing property who were eating at their father’s table but sleeping in their own houses need an eruv for each of them. Therefore if one of them forgot and did not make an eruv he is deemed to have ceded his rights. When? If they all bring their eruvin to one place but if the eruv came to them, or there were no other dwellers with them, they do not need an eruv.
