1 Kings 3:9

One of the chief functions of the Oriental monarch is always to hear and decide causes. Hence, supreme magistrates were naturally called “judges.” (See the introduction to the Book of Judges.) In the minds of the Jews the “judge” and the “prince” were always closely associated, the direct cognisance of causes being constantly taken by their chief civil governors. (See Exodus 2:14; Exodus 18:16, Exo 18:22; 1 Samuel 8:20; 2 Samuel 15:2.)

Good and bad - i. e. “right and wrong,” “justice and injustice.”
