Matthew Poole and continuators on 1 Samuel 21:11

And the servants of Achish said unto him, Is not this David the king of the land ? did they not sing one to another of him in dances, saying, Saul hath slain his thousands, and David his ten thousands .

Or, of this land; i. e. Of the Land of Canaan. They call him King, either more generally for the Governour, as that Word is used, Deut. 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.

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.
