1 Samuel 17:28-30 New Revised Standard Version (NRSV)
28 His eldest brother Eliab heard him talking to the men; and Eliab’s anger was kindled against David. He said, “Why have you come down? 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 just to see the battle.” 29 David said, “What have I done now? It was only a question.” 30 He turned away from him toward another and spoke in the same way; and the people answered him again as before.
