1 Samuel 17:17-20

Jesse said to his son David, “Take this half bushel of cooked grain and ten loaves of bread to your brothers in the camp. Also take ten pieces of cheese to the commander and to your brothers. See how your brothers are and bring back some proof to show me that they are all right. Your brothers are with Saul and the army in the Valley of Elah, fighting against the Philistines.” Early in the morning David left the sheep with another shepherd. He took the food and left as Jesse had told him. When David arrived at the camp, the army was going out to their battle positions, shouting their war cry.
