1 Samuel 17:27-28

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.”
