1 Samuel 17:42-47

When the Philistine looked and saw David, he despised him  because he was just a youth, healthy  , and handsome. He said to David, “Am I a dog  that you come against me with sticks? ”  Then he cursed David by his gods.  “Come here,” the Philistine called to David, “and I’ll give your flesh to the birds of the sky and the wild beasts! ”  David said to the Philistine, “You come against me with a sword, spear, and javelin, but I come against you in the name of the LORD of Armies, the God of the ranks of Israel #— #you have defied him.  Today, the LORD will hand you over to me. Today, I’ll strike you down, remove your head, and give the corpses  of the Philistine camp to the birds of the sky and the wild creatures of the earth. Then all the world will know that Israel has a God,  and this whole assembly will know that it is not by sword or by spear that the LORD saves,  for the battle is the LORD’s.  He will hand you over to us.”
