כֵּלִים שֶׁנָּפְלוּ לַבּוֹר וְנִשְׁתַּבְּרוּ בַּעַל הַבּוֹר פָּטוּר שֶׁנֶּאֱמַר (שמות כא לג) "וְנָפַל שָׁמָּה שּׁוֹר אוֹ חֲמוֹר" מִפִּי הַשְּׁמוּעָה לָמְדוּ שׁוֹר וְלֹא אָדָם חֲמוֹר וְלֹא כֵּלִים. אֲפִלּוּ נָפַל שׁוֹר בְּכֵלָיו וּמֵת הַשּׁוֹר וְנִשְׁתַּבְּרוּ כֵּלָיו חַיָּב עַל הַבְּהֵמָה וּפָטוּר עַל הַכֵּלִים:
When utensils fall into a cistern and break, the owner of the cistern is not liable. [This is derived from Exodus 21:33, which] states: "And an ox or a donkey fell there." The Oral Tradition interprets this as an exclusion: "'An ox' and not a man; 'a donkey' and not utensils." Even when an ox fell [into a cistern] when carrying utensils and died and broke the utensils, the owner is liable for the ox, but not for the utensils.
