46 This day the Lord will deliver you into my hand, and I will strike you down, and cut off your head; and I will give the dead bodies of the host of the Philistines this day to the birds of the air and to the wild beasts of the earth; that all the earth may know that there is a God in Israel,
Matthew Henry's Commentary on 1 Samuel 17:46
Commentary on 1 Samuel 17:40-47
