יִ֭בְצֹר ר֣וּחַ נְגִידִ֑ים נ֝וֹרָ֗א לְמַלְכֵי־אָֽרֶץ׃
Ukróca ducha książąt; groźny dla królów ziemi.
Rashi
לא יבצר מהם וגו' לעשות This is a question (although the ה which introduces an interrogative sentence is absent): SHALL THEY NOT BE RESTRAINED FROM DOING WHAT THEY IMAGINE TO DO? The word יבצר means “restraining”, as the Targum understands it; a similar instance is, (Psalms 76:13) “He restrains (יבצור) the spirit of princes”.
