וְהָיָ֗ה כִּֽי־יְבַצַּ֤ע אֲדֹנָי֙ אֶת־כָּל־מַֽעֲשֵׂ֔הוּ בְּהַ֥ר צִיּ֖וֹן וּבִירוּשָׁלִָ֑ם אֶפְקֹ֗ד עַל־פְּרִי־גֹ֙דֶל֙ לְבַ֣ב מֶֽלֶךְ־אַשּׁ֔וּר וְעַל־תִּפְאֶ֖רֶת ר֥וּם עֵינָֽיו׃
Wherefore it shall come to pass, that when the Lord hath performed His whole work upon mount Zion and on Jerusalem, I will punish the fruit of the arrogant heart of the king of Assyria, and the glory of his haughty looks.
