1 Samuel 17:28-30

17:28 When David’s oldest brother Eliab heard him speaking to the men, he became angry with David and said, “Why have you come down here? To whom did you entrust those few sheep in the desert? I am familiar with your pride and deceit! You have come down here to watch the battle!”

17:29 David replied, “What have I done now? Can’t I say anything?” 17:30 Then he turned from those who were nearby to someone else and asked the same question, but they gave him the same answer as before.
