1 Samuel 17:45-46

David 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. Today 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!
