1 Samuel 17:46-47

46Today, 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,

47and 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.”
