Jerusalem Talmud Eruvin 4.9

משנה: מִי שֶׁיָצָא לֵילֵךְ לְעִיר שֶׁמְּעָרְבִין בָּהּ וְהֶחֱזִירוֹ חֲבֵירוֹ הוּא מוּתָּר לֵילֵךְ וְכָל בְּנֵי הָעִיר אֲסוּרִין דִּבְרֵי רִבִּי יְהוּדָה. רִבִּי מֵאִיר אוֹמֵר כָּל שֶׁהוּא יָכוֹל לְעָרֵב וְלֹא עֵירֵב הֲרֵי זֶה חַמָּר גַּמָּל:

MISHNAH: If somebody started to go to another town for which one makes an eruv but another person intercepted him, he is permitted to go but the remainder of the town is forbidden, the words of Rebbi Jehudah. Rebbi Meïr says, anybody who could have made an eruv but did not make the eruv is a donkey driver-camel driver.

הלכה: פיס׳. מִי שֶׁיָצָא לֵילֵךְ לְעִיר. פָּתַר לַהּ תְּרֵין פְּּתָרִין. אָמַר. אֲנָא מְעָרֵב עָלֶיךָ וְעַל בְּנֵי קַרְתָּךְ. וְעִירֵב עַל בְּנֵי קַרְתֵּיהּ וְלֹא עִירֵב עִילוֹי. הוּא אָסוּר לֵילֵךְ בְּאוֹתָהּ הָרוּחַ וּמוֹתָּר בִּשְׁאָר כָּל הָרוּחוֹת שֶׁבְּעִירוֹ. וְהֵן מוּתָּרִין בְּאוֹתָהּ הָרוּחַ וַאֲסוּרִין בִּשְׁאָר כָּל הָרוּחוֹת שֶׁבְּעִירָן. פָּתַר לָהּ פְּתַר חוֹרָן. אָמַר לֵיהּ. אֲנָא מְעָרֵב עָלֶיךָ וְעַל בְּנֵי קַרְתָּךְ. וְלֹא עִירֵב לֹא עֲלוֹי ולֹא עַל בְּנֵי קַרְתֵּיהּ. הוּא מוּתָּר לֵילֵךְ בְּאוֹתָהּ הָרוּחַ. שֶׁכְּבָר קָנוּ לוֹ רַגְלָיו מֵאֶתְמוֹל. וְהֵן אֲסוּרִין לֵילֵךְ בְּאוֹתָהּ הָרוּחַ וּמוּתָּרִין בִּשְׁאָר כָּל הָרוּחוֹת שֶׁבְּעִירוֹ.

HALAKHAH: Paragraph. “If somebody started to go to another town.” One may give this two interpretations. If he said, I shall make an eruv for you and your townspeople, and made the eruv for his townspeople but not for him. He is forbidden to go in that direction but permitted all other directions in his town; they are permitted to go in that direction but forbidden all other directions in their town. One may give it another interpretation. If he said, I shall make an eruv for you and your townspeople and made the eruv neither for his townspeople nor for him. He is permitted to go in that direction for his feet already acquired for him the day before; they are forbidden to go in that direction but permitted all other directions in his town.
