משנה: אַנְשֵׁי חָצֵר וְאַנְשֵׁי מִרְפֶּסֶת שֶׁשָּׁכְחוּ וְלֹא עֵירְבוּ כָּל שֶׁגָּבוֹהַּ עֲשָׂרָה טְפָחִים לַמִּרְפֶּסֶת פָּחוּת מִכָּן לֶחֲצֵר. חוּלְיַת הַבּוֹר וְהַסֶּלַע גְּבוֹהִים עֲשָׂרָה טְפָחִים לַמִּרְפֶּסֶת פָּחוּת מִיכָּן לֶחָצֵר. בַּמֶּה דְבָרִים אֲמוּרִים בִּסְמוּכָה אֲבָל בְּמוּפְלֶגֶת אֲפִילוּ הִיא גְבוֹהָה עֲשָׂרָה טְפָחִים לֶחָצֵר. אֵי זוֹ הִיא סְמוּכָה כָּל שֶׁאֵינָהּ רְחוֹקָה אַרְבָּעָה טְפָחִים:
MISHNAH: If people of a courtyard and those on a balcony forgot and did not make an eruv, anything higher than ten hand-breadths belongs to the balcony, less than this to the courtyard. The enclosure of a cistern or a rock ten hand-breadths high belong to the balcony, less than this to the courtyard. When has this been said? If it is close. But if it is far away even if it is ten hand-breadths high it belongs to the courtyard. What is close? Any which is not four hand-breadths distant.
