1 Samuel 17:46-47

17:46 This very day the Lord will deliver you into my hand! I will strike you down and cut off your head. This day I will give the corpses of the Philistine army to the birds of the sky and the wild animals of the land. Then all the land will realize that Israel has a God 17:47 and all this assembly will know that it is not by sword or spear that the Lord saves! For the battle is the Lord’s, and he will deliver you into our hand.”
