שָׁבַ֥ר יְהוָ֖ה מַטֵּ֣ה רְשָׁעִ֑ים שֵׁ֖בֶט מֹשְׁלִֽים׃
The LORD hath broken the staff of the wicked, the sceptre of the rulers,
Rashi on Isaiah
The Lord has broken the staff of the wicked For he would smite peoples with wrath.
Ibn Ezra on Isaiah
The staff. A figure signifying kingdom. The rod. The same. The king is like a shepherd, the people like his flock.
