דברים כ״ה:י״א-י״ב

כי ינצו אנשים. סוֹפוֹ לָבֹא לִידֵי מַכּוֹת, כְּמוֹ שֶׁנֶּאֱמַר מיד מכהו, אֵין שָׁלוֹם יוֹצֵא מִתּוֹךְ יְדֵי מַצּוּת (ספרי):

If men engage in an altercation. Ultimately, they will come to blows, as it is said, “From his assailant.” No peace can result from altercation.

וקצתה את כפה. מָמוֹן דְּמֵי בָשְׁתּוֹ, הַכֹּל לְפִי הַמְבַיֵּשׁ וְהַמִּתְבַּיֵּשׁ; אוֹ אֵינוֹ אֶלָּא יָדָהּ מַמָּשׁ? נֶאֱמַר כָּאן "לֹא תָחוֹס", וְנֶאֱמַר לְהַלָּן בְּעֵדִים זוֹמְמִים (דברים י"ט) "לֹא תָחוֹס", מַה לְּהַלָן מָמוֹן אַף כָּאן מָמוֹן (ספרי; עי' בבא קמא כ"ח):

You shall sever her hand. Monetary payment for his humiliation, varying according to the one who caused the humiliation, and the one who suffered it. But perhaps this refers literally to her hand? It is said here, “have no compassion,” and it is said elsewhere, concerning scheming witnesses, “Have no compassion.” Just as there, the reference is to monetary payment, here, too, the reference is to monetary payment.
