1 Samuel 17:20-25

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. The Israelites, to a man, fell back the moment they saw the giant—totally frightened. The talk among the troops was, “Have you ever seen anything like this, this man openly and defiantly challenging Israel? The man who kills the giant will have it made. The king will give him a huge reward, offer his daughter as a bride, and give his entire family a free ride.”
