אֶת־עַ֥ם נוֹעָ֖ז לֹ֣א תִרְאֶ֑ה עַ֣ם עִמְקֵ֤י שָׂפָה֙ מִשְּׁמ֔וֹעַ נִלְעַ֥ג לָשׁ֖וֹן אֵ֥ין בִּינָֽה׃
Engkau tidak akan melihat bangsa yang berbahasa asing itu, bangsa yang bahasanya terlalu sulit untuk dipahami, yang lidahnya terdengar aneh sehingga tidak dapat dimengerti.
Rashi
a people of a strange tongue With another language, which is not the Holy Tongue. A similar expression is (Isa. 33:19): “A people of a strange tongue you shall not see, a people of speech too obscure, etc.” The “nun” and the “lammed” are interchangeable, like נִשְׁכָּה, chamber, which is [equivalent to] לִשְׁכָּה, in the Book of Ezra (Neh. 13:7).
