2 Samuel 8:16

Jehoshaphat the son of Ahilud was recorder— i.e. as is generally believed, remembrancer, or writer of chronicles: an employment of no mean estimation in the Eastern world, where it was customary with kings to keep daily registers of all the transactions of their reign; and a trust, which whoever discharged efficiently must be let into the true springs and secrets of action, and consequently must be received into the inmost confidence. The sacred Writer no sooner gives us an account of David's executing judgment and justice, but he immediately adds a lift of the great officers then employed by him; for a principal part of a king's wisdom, as well as of his felicity, consists in the choice of able ministers, to discharge the great offices of the state.
