1 Samuel 17:23-30

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.
