1 Samuel 17:23-30

While he was talking with them, Goliath, the Philistine champion from Gath, came out. He shouted things against Israel as usual, and David heard him. When the Israelites saw Goliath, they were very much afraid and ran away. They said, “Look at this man! He keeps coming out to challenge Israel. The king will give much money to whoever kills him. He will also let whoever kills him marry his daughter. And his father’s family will not have to pay taxes in Israel.” David asked the men who stood near him, “What will be done to reward the man who kills this Philistine and takes away the shame from Israel? Who does this uncircumcised Philistine think he is? Does he think he can speak against the armies of the living God?” The Israelites told David what would be done for the man who would kill Goliath. When David’s oldest brother Eliab heard David talking with the soldiers, he was angry with David. He asked David, “Why did you come here? Who’s taking care of those few sheep of yours in the desert? I know you are proud and wicked at heart. You came down here just to watch the battle.” David asked, “Now what have I done wrong? Can’t I even talk?” When he turned to other people and asked the same questions, they gave him the same answer as before.
