אֶת־עַ֥ם נוֹעָ֖ז לֹ֣א תִרְאֶ֑ה עַ֣ם עִמְקֵ֤י שָׂפָה֙ מִשְּׁמ֔וֹעַ נִלְעַ֥ג לָשׁ֖וֹן אֵ֥ין בִּינָֽה׃
Das Barbarenvolk siehst du nicht mehr, das Volk dunkler Rede, nicht zu verstehen, stotternder Zunge, ohne Sinn.
Rashi on Isaiah
A people of a strange tongue (נוֹעָז) like לוֹעֵז. These are all the heathens, whose language is not the holy tongue. ([Other editions read:] These are Assyria and Babylon, whose language is not the holy tongue.) ([Manuscripts read:] These are all the nations whose language is not the holy tongue.)
Ibn Ezra on Isaiah
נועז We cannot say, whether the נ is radical, or the characteristic prefix of the Niphal; the word is hap. leg.; it means a stranger or a strange man; to consider לועז═נועז speaking a foreign language, is incorrect.
Rashi on Isaiah
you shall not see You shall not esteem in your heart, for they shall all be dark and humble.
