46 This very 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 Philistine army this very day to the birds of the air and to the wild animals of the earth, so 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
(Read 1 Samuel 17:40-47)
