1 Samuel 17:45-47

45David replied to the Philistine, “You come to me with sword, spear, and javelin, but I come to you in the name of the Lord of Heaven’s Armies—the God of the armies of Israel, whom you have defied.

46Today the Lord will conquer you, and I will kill you and cut off your head. And then I will give the dead bodies of your men to the birds and wild animals, and the whole world will know that there is a God in Israel!

47And everyone assembled here will know that the Lord rescues his people, but not with sword and spear. This is the Lord’s battle, and he will give you to us!”
