1 Samuel 21:11

The king of the land, or, of this land, i.e. of the land of Canaan. They call him king, either more generally for the governor, as that word is used Deuteronomy 33:5, for the most eminent captain and commander, and, as it were, the king of the Israelitish armies; or rather, more specially, the king, to wit, 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 ears. Did they not sing one to another of him in dances, saying, Saul hath slain his thousands, and David his ten thousands? and therefore consider what to do; and now thine and our great enemy is in thy hand, be sure thou never let him go alive.
