1 Samuel 17:28-30

Now Eliab his oldest brother heard what he said to the men; and Eliab’s anger burned against David and he said, “Why have you come down here? With whom did you leave those few sheep in the wilderness? I know your presumption (overconfidence) and the evil of your heart; for you have come down in order to see the battle.” But David said, “What have I done now? Was it not just a [harmless] question?” Then David turned away from Eliab to someone else and asked the same question; and the people gave him the same answer as the first time.
