King James Version (KJV)
So shall he sprinkle many nations; the kings shall shut their mouths at him: for {that} which had not been told them shall they see; and {that} which they had not heard shall they consider.
Modern English
so he will cleanse many nations. Kings will shut their mouths at him: for they will see that which had not been told them; and they will understand that which they had not heard.
Hebrew
כֵּ֤ן יַזֶּה֙ גּוֹיִ֣ם רַבִּ֔ים עָלָ֛יו יִקְפְּצ֥וּ מְלָכִ֖ים פִּיהֶ֑ם כִּ֠י אֲשֶׁ֨ר לֹֽא־סֻפַּ֤ר לָהֶם֙ רָא֔וּ וַאֲשֶׁ֥ר לֹֽא־שָׁמְע֖וּ הִתְבּוֹנָֽנוּ׃
