Targum for Isaiah 36:11

וַיֹּ֣אמֶר אֶלְיָקִים֩ וְשֶׁבְנָ֨א וְיוֹאָ֜ח אֶל־רַב־שָׁקֵ֗ה דַּבֶּר־נָ֤א אֶל־עֲבָדֶ֙יךָ֙ אֲרָמִ֔ית כִּ֥י שֹׁמְעִ֖ים אֲנָ֑חְנוּ וְאַל־תְּדַבֵּ֤ר אֵלֵ֙ינוּ֙ יְהוּדִ֔ית בְּאָזְנֵ֣י הָעָ֔ם אֲשֶׁ֖ר עַל־הַחוֹמָֽה׃

Then said Eliakim and Shebna and Joah unto Rab-shakeh: ‘Speak, I pray thee, unto thy servants in the Aramean language, for we understand it; and speak not to us in the Jews’language, in the ears of the people that are on the wall.’
