20 So David left the sheep with another shepherd and set out early the next morning with the gifts, as Jesse had directed him. He arrived at the camp just as the Israelite army was leaving for the battlefield with shouts and battle cries. 21 Soon the Israelite and Philistine forces stood facing each other, army against army. 22 David left his things with the keeper of supplies and hurried out to the ranks to greet his brothers. 23 As he was talking with them, Goliath, the Philistine champion from Gath, came out from the Philistine ranks. Then David heard him shout his usual taunt to the army of Israel.
24 As soon as the Israelite army saw him, they began to run away in fright. 25 “Have you seen the giant?” the men asked. “He comes out each day to defy Israel. The king has offered a huge reward to anyone who kills him. He will give that man one of his daughters for a wife, and the man’s entire family will be exempted from paying taxes!”
26 David asked the soldiers standing nearby, “What will a man get for killing this Philistine and ending his defiance of Israel? Who is this pagan Philistine anyway, that he is allowed to defy the armies of the living God?”
28 But when David’s oldest brother, Eliab, heard David talking to the men, he was angry. “What are you doing around here anyway?” he demanded. “What about those few sheep you’re supposed to be taking care of? I know about your pride and deceit. You just want to see the battle!”
29 “What have I done now?” David replied. “I was only asking a question!” 30 He walked over to some others and asked them the same thing and received the same answer. 31 Then David’s question was reported to King Saul, and the king sent for him.
32 “Don’t worry about this Philistine,” David told Saul. “I’ll go fight him!”
34 But David persisted. “I have been taking care of my father’s sheep and goats,” he said. “When a lion or a bear comes to steal a lamb from the flock, 35 I go after it with a club and rescue the lamb from its mouth. If the animal turns on me, I catch it by the jaw and club it to death. 36 I have done this to both lions and bears, and I’ll do it to this pagan Philistine, too, for he has defied the armies of the living God! 37 The Lord who rescued me from the claws of the lion and the bear will rescue me from this Philistine!”
Saul finally consented. “All right, go ahead,” he said. “And may the Lord be with you!”
38 Then Saul gave David his own armor—a bronze helmet and a coat of mail. 39 David put it on, strapped the sword over it, and took a step or two to see what it was like, for he had never worn such things before.
“I can’t go in these,” he protested to Saul. “I’m not used to them.” So David took them off again. 40 He picked up five smooth stones from a stream and put them into his shepherd’s bag. Then, armed only with his shepherd’s staff and sling, he started across the valley to fight the Philistine.
41 Goliath walked out toward David with his shield bearer ahead of him, 42 sneering in contempt at this ruddy-faced boy. 43 “Am I a dog,” he roared at David, “that you come at me with a stick?” And he cursed David by the names of his gods. 44 “Come over here, and I’ll give your flesh to the birds and wild animals!” Goliath yelled.
45 David replied to the Philistine, “You come to me with sword, spear, and javelin, but I come to you in the name of the Lord of Heaven’s Armies—the God of the armies of Israel, whom you have defied. 46 Today the Lord will conquer you, and I will kill you and cut off your head. And then I will give the dead bodies of your men to the birds and wild animals, and the whole world will know that there is a God in Israel! 47 And everyone assembled here will know that the Lord rescues his people, but not with sword and spear. This is the Lord’s battle, and he will give you to us!”
48 As Goliath moved closer to attack, David quickly ran out to meet him. 49 Reaching into his shepherd’s bag and taking out a stone, he hurled it with his sling and hit the Philistine in the forehead. The stone sank in, and Goliath stumbled and fell face down on the ground.
