1 Samuel 17:28-30

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.
