כִּ֡י לֹא֩ אֶל־עַ֨ם עִמְקֵ֥י שָׂפָ֛ה וְכִבְדֵ֥י לָשׁ֖וֹן אַתָּ֣ה שָׁל֑וּחַ אֶל־בֵּ֖ית יִשְׂרָאֵֽל׃
因為你被差遣去的，不是到言語難懂、口舌笨拙的民那裡，而是到以色列家去。
Rashi
of an unfathomable language Who have a deep language, which you do not understand.
Rashi
to the house of Israel But to the house of Israel I send you, whose language is like your language.
