וּבְנֵיהֶ֗ם חֲצִי֙ מְדַבֵּ֣ר אַשְׁדּוֹדִ֔ית וְאֵינָ֥ם מַכִּירִ֖ים לְדַבֵּ֣ר יְהוּדִ֑ית וְכִלְשׁ֖וֹן עַ֥ם וָעָֽם׃
La moitié de leurs enfants parlaient la langue d’Asdod; ils ne savaient point parler le judéen, mais se servaient de l’idiome de tel ou tel autre peuple.
Ibn Ezra
And the second thing, is that his poems are mixed with Talmudic language. And it is known that there are many languages in the Talmud, not all of which are the Holy Tongue. And thus they said, the language of Scripture is itself and the language of Talmud is itself (Avodah Zarah 58b:4). And who brought upon us this stress, to pray in foreign languages? Didn't Nehemiah rebuke those speaking Ashdodian (Nehemiah 13:24)? All the more so praying in it! And why not learn from the set prayers, which are entirely written in pure words of the Holy Tongue? And why would we pray in the languages of Media and Persia and Christendom and Islam?
