כִּ֡י לֹא֩ אֶל־עַ֨ם עִמְקֵ֥י שָׂפָ֛ה וְכִבְדֵ֥י לָשׁ֖וֹן אַתָּ֣ה שָׁל֑וּחַ אֶל־בֵּ֖ית יִשְׂרָאֵֽל׃
Rashi on Ezekiel
of an unfathomable language Who have a deep language, which you do not understand.
Rashi on Ezekiel
to the house of Israel But to the house of Israel I send you, whose language is like your language.
