2 Samuel 8:13-18

David built a victory monument on his return from defeating the Arameans. Abishai son of Zeruiah fought and defeated the Edomites in the Salt Valley. Eighteen thousand of them were killed. David set up a puppet government in Edom, and the Edomites became subjects under David. GOD gave David victory wherever he marched. Thus David ruled over all of Israel. He ruled well—fair and evenhanded in all his duties and relationships. Joab son of Zeruiah was head of the army; Jehoshaphat son of Ahilud was clerk; Zadok son of Ahitub and Ahimelech son of Abiathar were priests; Seraiah was secretary; Benaiah son of Jehoiada was over the Kerethites and Pelethites; And David’s sons were priests.
