לִ֤י גִלְעָ֨ד ׀ וְלִ֬י מְנַשֶּׁ֗ה וְ֭אֶפְרַיִם מָע֣וֹז רֹאשִׁ֑י יְ֝הוּדָ֗ה מְחֹֽקְקִי׃
Gilead is mine, and Manasseh is mine; Ephraim also is the defence of my head; Judah is my sceptre.
Rashi on Psalms
my lawgiver My ministers. מחקקי is an expression of administration, that he makes the law and sends scrolls and commands, as (Gen. 49:10): “The scepter will not turn away from Judah, nor the lawgiver from between his feet.”
