15 So David reigned over all Israel; and David administered judgment and justice to all his people. 16 Joab the son of Zeruiah was over the army; Jehoshaphat the son of Ahilud was recorder; 17 Zadok the son of Ahitub and Ahimelech the son of Abiathar were the priests; Seraiah was the scribe; 18 Benaiah the son of Jehoiada was over both the Cherethites and the Pelethites; and David's sons were chief ministers.

Commentary on 2 Samuel 8:15-18
(Read 2 Samuel 8:15-18)
David neither did wrong, nor denied or delayed right to any. This speaks his close application to business; also his readiness to admit all addresses and appeals made to him. He had no respect of persons in judgment. Herein he was a type of Christ. To Him let us submit, his friendship let us seek, his service let us count our pleasure, diligently attending to the work he assigns to each of us. David made his sons chief rulers; but all believers, Christ's spiritual seed, are better preferred, for they are made kings and priests to our God, Revelation 1:6.
