1 Samuel 17:15-30

but David went back and forth so he could help his father with the sheep in Bethlehem. For forty days, every morning and evening, the Philistine champion strutted in front of the Israelite army. One day Jesse said to David, “Take this basket of roasted grain and these ten loaves of bread, and carry them quickly to your brothers. And give these ten cuts of cheese to their captain. See how your brothers are getting along, and bring back a report on how they are doing.” David’s brothers were with Saul and the Israelite army at the valley of Elah, fighting against the Philistines. 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. Soon the Israelite and Philistine forces stood facing each other, army against army. David left his things with the keeper of supplies and hurried out to the ranks to greet his brothers. 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. As soon as the Israelite army saw him, they began to run away in fright. “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!” 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?” And these men gave David the same reply. They said, “Yes, that is the reward for killing him.” 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!” “What have I done now?” David replied. “I was only asking a question!” He walked over to some others and asked them the same thing and received the same answer.
