Wesley's Notes for 1 Samuel 21:13

21:11 King of the land - Of Canaan. They call him king, either more generally for the governor, the most eminent captain and commander, or, as the king elect, the person designed to be king: for, by this time, the fame of Saul's rejection, and David's destination to the kingdom, was got abroad among the Israelites, and from them, probably to the Philistines. Did they not sing, &c. - And therefore consider what to do; and now our great enemy is in thy hand, be sure thou never let him go alive.

21:12 Was afraid - Lest either their revenge or policy should prompt them to kill him. Perhaps he was the more apprehensive, because he wore Goliath's sword, which was probably well known at Gath. He now learned by experience what he afterward taught us, #Psal 118:9|. It is better to trust in the Lord, than to put any confidence in princes.

21:15 Mad men - It is highly probable, Achish was aware, that this madness was counterfeit. But being desirous to preserve David, he speaks as if he thought it real.
