8:18 And Benaiah the son of Jehoiada [was over] both the {h} Cherethites and the Pelethites; and David's sons were chief rulers.

(h) The Cherethites and Pelethites were as the king's guard, and had charge of his person.

8:18 Cherethites, and c. - The Cherethites and Pelethites were undoubtedly soldiers, and such as were eminent for their valour and fidelity. Most probable they were the king's guards, which consisted of these two bands, who might be distinguished either by their several weapons, or by the differing time or manner of their service. They are supposed to be thus called either, first, from their office, which was upon the king's command to cut off or punish offenders, and to preserve the king's person, as their names in the Hebrew tongue may seem to imply. Or, secondly, from some country, or place to which they had relation. As for the Cherithites, it is certain they were ether a branch of the Philistines, or a people neighbouring to them, and so might the Pelethites be too, though that be not related in scripture. And these Israelites and soldiers of David might be so called, either because they went and lived with David when he dwelt in those parts or, for some notable exploit against, or victory over these people.

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, Re 1:6.
