32:21ל״ב:כ״א
1 א

אכפרה פניו. אֲבַטֵּל רָגְזוֹ; וְכֵן וְכֻפַּר בְּרִיתְכֶם אֶת מָוֶת (ישעיהו כ"ח), לֹא תוּכְלִי כַּפְּרָהּ (שם מ"ז). וְנִרְאֶה בְעֵינַי שֶׁכָּל כַּפָּרָה שֶׁאֵצֶל עָוֹן וְחֵטְא וְאֵצֶל פָּנִים כֻּלָּן לְשׁוֹן קִנּוּחַ וְהַעֲבָרָה הֵן, וְלָשׁוֹן אֲרַמִּי הוּא, וְהַרְבֵּה בַּתַּלְמוּד וְכַפֵּר יְדֵיהּ, בָּעֵי לְכַפּוּרֵי יְדֵי בְּהַהוּא גַבְרָא, וְגַם בִּלְשׁוֹן הַמִּקְרָא נִקְרָאִים הַמִּזְרָקִים שֶׁל קֹדֶשׁ כְּפוֹרֵי זָהָב (עזרא א'), עַל שֵׁם שֶׁהַכֹּהֵן מְקַנֵּחַ יָדָיו בָּהֶן בִּשְׂפַת הַמִּזְרָק:

אכפרה פניו I WILL APPEASE HIM — I will remove his anger. Similarly, (Isaiah 28:18) "and your covenant with death shall be annulled (וכפר)”; (Isaiah 47:11) “Thou shalt not be able to put it away (וכפרה”. I am of the opinion that wherever the verb כפר is used in association with iniquity and sin and in association with anger (פנים), it always signifies wiping away, removing. It is an Aramaic expression occurring frequently in the Talmud: “He wiped his hand off (כפר ידיה)”, and (Gittin 56a) ‘‘he wants to wipe (לכפורי) his hands off on this man” (i.e. he desires to put the responsibility upon me). In Biblical Hebrew, also, the bowls of the Sanctuary are called, (Ezra 1:10) "כפורי of gold” — and they are so called because the priest wiped his hands on them — on the rim of the bowl (Zevachim 93b).
