45 Then David said to the Philistine , "You come to me with a sword , a spear , and a javelin , but I come to you in the name of the Lord of hosts , the God of the armies of Israel , whom you have taunted . 46 "This day the Lord will deliver you up into my hands , and I will strike you down and remove your head from you. And I will give the dead bodies of the army of the Philistines this day to the birds of the sky and the wild beasts of the earth , that all the earth may know that there is a God in Israel ,

Commentary on 1 Samuel 17:40-47
(Read 1 Samuel 17:40-47)
