1 Samuel 17:46-47

46Today the Lord will hand you over to me. I will strike you down and cut off your head. And this day I will give the dead bodies of the Philistine army to the birds and the wild animals. The whole world will know that Israel has a God.

47Then everyone gathered here will know that the Lord can save without sword or spear, because the Lord determines every battle’s outcome. He will hand all of you over to us.”
