1 Samuel 17:20-23

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. The Israelites and Philistines were lining up their men to face each other in battle. David left the food with the man who kept the supplies and ran to the battle line to talk to his brothers. While he was talking with them, Goliath, the Philistine champion from Gath, came out. He shouted things against Israel as usual, and David heard him.
