כֵּ֤ן יַזֶּה֙ גּוֹיִ֣ם רַבִּ֔ים עָלָ֛יו יִקְפְּצ֥וּ מְלָכִ֖ים פִּיהֶ֑ם כִּ֠י אֲשֶׁ֨ר לֹֽא־סֻפַּ֤ר לָהֶם֙ רָא֔וּ וַאֲשֶׁ֥ר לֹֽא־שָׁמְע֖וּ הִתְבּוֹנָֽנוּ׃
So shall he startle many nations, Kings shall shut their mouths because of him; From that which had not been told them shall they see, And that which they had not heard shall they perceive.
