18כְּשֵׁם שֶׁאוֹמְדִין לְמִיתָה כָּךְ אוֹמְדִין לִנְזָקִין. כֵּיצַד. הֲרֵי שֶׁהִכָּה חֲבֵרוֹ בִּצְרוֹר קָטָן שֶׁאֵין בּוֹ כְּדֵי לְהַזִּיק אוֹ בְּקֵיסָם שֶׁל עֵץ קָטָן וְחָבַל בּוֹ חַבָּלָה שֶׁאֵין חֵפֶץ זֶה רָאוּי לַעֲשׂוֹתוֹ הֲרֵי זֶה פָּטוּר. שֶׁנֶּאֱמַר (שמות כא יח) "בְּאֶבֶן אוֹ בְאֶגְרֹף" דָּבָר הָרָאוּי לְהַזִּיק. אֲבָל חַיָּב הוּא בְּבֹשֶׁת בִּלְבַד. אֲפִלּוּ רָקַק בְּגוּפוֹ שֶׁל חֲבֵרוֹ חַיָּב בְּבשֶׁת. לְפִיכָךְ צְרִיכִין הָעֵדִים לֵידַע בְּמָה הִזִּיק וּמְבִיאִין הַחֵפֶץ שֶׁהִזִּיק בּוֹ לְבֵית דִּין עַד שֶׁאוֹמְדִין אוֹתוֹ וְדָנִין עָלָיו. וְאִם אָבַד הַחֵפֶץ וְאָמַר הַחוֹבֵל לֹא הָיָה בּוֹ כְּדֵי לְהַזִּיק וּכְמוֹ אָנוּס אֲנִי. וְהַנֶּחְבָּל אוֹמֵר הָיָה בּוֹ כְּדֵי לְהַזִּיק. יִשָּׁבַע הַנֶּחְבָּל וְיִטּל כְּמוֹ שֶׁיִּתְבָּאֵר:
Just as an evaluation is made with regard to death, so too, an evaluation is made with regard to damages. What is implied? If he strikes a colleague with a small stone that is not large enough to cause injury, or a small sliver of wood and causes an injury that this article is not ordinarily capable of causing, he is not liable. This concept is alluded to by Exodus 21:18, which speaks of "a man strik(ing) a colleague with a stone or a fist" - i.e., an entity that is capable of causing injury. He is, however, liable for the embarrassment that he caused. [For even if he merely spat on his colleague's person, he is liable for the embarrassment that he caused. Accordingly, the witnesses have to know the article that caused the injury. This article should be brought to the court, and an evaluation is made concerning it, and a reckoning. If the article that caused the injury was lost and the person who caused the injury claims: "It was not sufficient to cause the injury. The injury occurred because of forces beyond my control," and the person who was injured claims: "It was sufficient to cause the injury," the person who was injured should support his claim with an oath and collect his due, as will be explained.
