משנה: אֵין מְגַלְגְּלִין בְּטוֹפֵיחַ דִּבְרֵי רִבִּי מֵאִיר. וַחֲכָמִים מַתִּירִין מִפְּנֵי שֶׁאֵיפְשָׁר.
MISHNAH: One does not use a waterwheel with buckets, the words of Rebbi Meïr. But the Sages do permit it, because it is impossible. A householder wandering from one place to another who was in need of taking gleanings, forgotten sheaves, peah, and tithes of the poor should repay them once he comes home, the words of Rebbi Eliezer. But the Sages say, he was poor at that moment.
