11הָיוּ הַנִּזָּקִין שְׁנַיִם אֶחָד גָּדוֹל וְאֶחָד קָטָן וְהַמַּזִּיקִין אֶחָד גָּדוֹל וְאֶחָד קָטָן. הַנִּזָּק אוֹמֵר גָּדוֹל הִזִּיק אֶת הַגָּדוֹל וְהַקָּטָן אֶת הַקָּטָן וְהַמַּזִּיק אוֹמֵר לֹא כִּי אֶלָּא קָטָן הִזִּיק אֶת הַגָּדוֹל וְגָדוֹל אֶת הַקָּטָן. אוֹ שֶׁהָיָה אֶחָד תָּם וְאֶחָד מוּעָד הַנִּזָּק אוֹמֵר הַמּוּעָד הִזִּיק אֶת הַגָּדוֹל וְתָם הִזִּיק אֶת הַקָּטָן וְהַמַּזִּיק אוֹמֵר תָּם הִזִּיק אֶת הַגָּדוֹל וְהַמּוּעָד הִזִּיק אֶת הַקָּטָן. הַמּוֹצִיא מֵחֲבֵרוֹ עָלָיו הָרְאָיָה. לֹא הָיְתָה שָׁם רְאָיָה בְּרוּרָה הַמַּזִּיק פָּטוּר. לְמָה זֶה דּוֹמֶה לְזֶה טוֹעֵן אֶת חֲבֵרוֹ חִטִּים וְהוֹדָה לוֹ בִּשְׂעוֹרִים שֶׁהוּא נִשְׁבַּע שְׁבוּעַת הֶסֵּת וּפָטוּר אַף מִדְּמֵי שְׂעוֹרִים כְּמוֹ שֶׁיִּתְבָּאֵר בְּהִלְכוֹת טוֹעֵן. וְאִם תָּפַס הַנִּזָּק הֲרֵי זֶה מְשַׁלֵּם לַקָּטָן מִן הַגָּדוֹל וְלַגָּדוֹל מִן הַקָּטָן כְּמוֹ שֶׁהוֹדָה הַמַּזִּיק. אֲבָל אִם לֹא תָּפַס אֵין מוֹצִיאִין מִן הַמַּזִּיק כְּלוּם:
[The following rules apply when] two oxen were damaged, one large and one small, and there were two oxen that caused the damage, one large and one small. The person whose oxen were damaged claims: the large ox damaged the large ox, and the small ox damaged the small ox. The person whose oxen caused the damage, by contrast claims: "No. It was the small ox that damaged the large one, and the large ox that damaged the small one." [A similar dispute arises if] one [of the oxen that caused the damage] was mu'ad and the other tam. The person whose oxen were damaged claims: the ox that was mu'ad damaged the large ox, and the ox that was tam damaged the small ox. By contrast, the person whose oxen caused the damage claims: "It was the ox that was tam that damaged the large one, and the ox that was mu'ad that damaged the small one." [In both these instances,] the burden of proof is upon the one who wishes to exact payment. If there is no proof, the one who caused the damage is not liable [at all]. To what can this be compared? To an instance where a person claims that a colleague owes him wheat, and the colleague admits to owing him barley. In such a case, [the defendant] is required to take a Rabbinic oath and then is not liable, even for the barley, as will be explained in Hilchot To'en.If the person whose oxen were damaged seizes possession [of property belonging to the person whose oxen caused the damage], he may take payment for the damages to the small ox from the body of the large ox and may take payment for the damages to the large ox from the body of the small ox, as the person who caused the damages admitted. If he did not seize possession [of such property], however, no money at all is expropriated from the person whose oxen caused the damage.
