גֵּוִי֙ נָתַ֣תִּי לְמַכִּ֔ים וּלְחָיַ֖י לְמֹֽרְטִ֑ים פָּנַי֙ לֹ֣א הִסְתַּ֔רְתִּי מִכְּלִמּ֖וֹת וָרֹֽק׃
Meinen Rücken bot ich den Schlägern und meine Wange den Raufenden, mein Angesicht barg ich nicht vor Schmähung und Speien [derer, welche von der Heimkehr nichts wissen wollten].
Rashi on Isaiah
I gave my back to smiters He said to me, Isaiah, My children are obstinate; My children are bothersome. [You may go] on the condition that you do not become angry with them. I said to Him, On that condition.
Ibn Ezra on Isaiah
I gave my back, etc. I did not care that I had to expose my back to strokes for the sake of His name.
