1 Samuel 17:46-47

This day the Lord will give you up into my hands, and I will overcome you, and take your head off you; and I will give the bodies of the Philistine army to the birds of the air and the beasts of the earth today, so that all the earth may see that Israel has a God; And all these people who are here today may see that the Lord does not give salvation by sword and spear: for the fight is the Lord's, and he will give you up into our hands.
