הִנְנִ֣י מֵבִיא֩ עֲלֵיכֶ֨ם גּ֧וֹי מִמֶּרְחָ֛ק בֵּ֥ית יִשְׂרָאֵ֖ל נְאֻם־יְהֹוָ֑ה גּ֣וֹי ׀ אֵיתָ֣ן ה֗וּא גּ֤וֹי מֵעוֹלָם֙ ה֔וּא גּ֚וֹי לֹא־תֵדַ֣ע לְשֹׁנ֔וֹ וְלֹ֥א תִשְׁמַ֖ע מַה־יְדַבֵּֽר׃
Lo, I will bring a nation upon you from far, O house of Israel, saith the LORD; It is an enduring nation, It is an ancient nation, A nation whose language thou knowest not, Neither understandest what they say.
Rashi on Jeremiah
It is an ancient nation From days of yore it began to rebel against Me, in the generation of separation in the land of Shinar.
