2 Samuel 8:15-18

And David reigned over all Israel; and David executed judgment and justice unto all his people. And Joab the son of Zeruiah was over the host; and Jehoshaphat the son of Ahilud was recorder; and Zadok the son of Ahitub, and Ahimelech the son of Abiathar, were the priests; and Seraiah was the scribe; and Benaiah the son of Jehoiada was over both the Cherethites and the Pelethites; and David's sons were chief rulers.
