משנה: הַזּוֹרֵק אַרְבַּץ אַמּוֹת בַּכּוֹתֶל לְמַעְלָה מֵעֲשָׂרָה טְפָחִים כְּזוֹרֵק בָּאֲוִיר לְמַטָּה מֵעֲשָׂרָה טְפָחִים כְּזוֹרֵק בָּאָרֶץ וְהַזּוֹרֵק בָּאָרֶץ אַרְבַּע אַמּוֹת חַיָיב. זָרַק לְתוֹךְ אַרְבַּע אַמּוֹת וְנִתְגַּלְגֵּל חוּץ לְאַרְבַּע אַמּוֹת פָּטוּר. חוּץ לְאַרְבַּע אַמּוֹת וְנִתְגַּלְגֵּל לְתוֹךְ אַרְבַּע אַמּוֹת חַיָיב:
MISHNAH: One who throws four cubits to a wall higher than ten hand-breadths is like one who throws in the air, lower than ten hand-breadths is like one who throws on the ground and one who throws four cubits on the ground is liable. One who threw less than four cubits and it rolled further than four cubits is not liable; one who threw more than four cubits and it rolled back within four cubits is liable.
