1 Samuel 17:17-23

One day, Jesse told David his son, “Take this sack of cracked wheat and these ten loaves of bread and run them down to your brothers in the camp. And take these ten wedges of cheese to the captain of their division. Check in on your brothers to see whether they are getting along all right, and let me know how they’re doing—Saul and your brothers, and all the Israelites in their war with the Philistines in the Oak Valley.” David was up at the crack of dawn and, having arranged for someone to tend his flock, took the food and was on his way just as Jesse had directed him. He arrived at the camp just as the army was moving into battle formation, shouting the war cry. Israel and the Philistines moved into position, facing each other, battle-ready. David left his bundles of food in the care of a sentry, ran to the troops who were deployed, and greeted his brothers. While they were talking together, the Philistine champion, Goliath of Gath, stepped out from the front lines of the Philistines, and gave his usual challenge. David heard him.
