1 Samuel 17:36-49 Common English Bible (CEB)
36 Your servant has fought both lions and bears. This uncircumcised Philistine will be just like one of them because he has insulted the army of the living God.
37 “The Lord,” David added, “who rescued me from the power of both lions and bears, will rescue me from the power of this Philistine.”
“Go!” Saul replied to David. “And may the Lord be with you!”
38 Then Saul dressed David in his own gear, putting a coat of armor on him and a bronze helmet on his head. 39 David strapped his sword on over the armor, but he couldn’t walk around well because he’d never tried it before. “I can’t walk in this,” David told Saul, “because I’ve never tried it before.” So he took them off. 40 He then grabbed his staff and chose five smooth stones from the streambed. He put them in the pocket of his shepherd’s bag and with sling in hand went out to the Philistine.
41 The Philistine got closer and closer to David, and his shield-bearer was in front of him. 42 When the Philistine looked David over, he sneered at David because he was just a boy; reddish brown and good-looking.
43 The Philistine asked David, “Am I some sort of dog that you come at me with sticks?” And he cursed David by his gods. 44 “Come here,” he said to David, “and I’ll feed your flesh to the wild birds and the wild animals!”
45 But David told the Philistine, “You are coming against me with sword, spear, and scimitar, but I come against you in the name of the Lord of heavenly forces, the God of Israel’s army, the one you’ve insulted. 46 Today the Lord will hand you over to me. I will strike you down and cut off your head! Today I will feed your dead body and the dead bodies of the entire Philistine camp[a] to the wild birds and the wild animals. Then the whole world will know that there is a God on Israel’s side. 47 And all those gathered here will know that the Lord doesn’t save by means of sword and spear. The Lord owns this war, and he will hand all of you over to us.”
48 The Philistine got up and moved closer to attack David, and David ran quickly to the front line to face him. 49 David put his hand in his bag and took out a stone. He slung it, and it hit the Philistine on his forehead. The stone penetrated his forehead, and he fell facedown on the ground.
