1 Samuel 17:28-30

Now Eliab his eldest brother heard when he spoke to the men. And Eliab’s anger was kindled against David, and he said, “Why have you come down? And with whom have you left those few sheep in the wilderness? I know your presumption and the evil of your heart, for you have come down to see the battle.” And David said, “What have I done now? Was it not but a word?” And he turned away from him toward another, and spoke in the same way, and the people answered him again as before.
