1 Samuel 17:20-22

New King James Version

²⁰ So David rose early in the morning, left the sheep with a keeper, and took the things and went as Jesse had commanded him. And he came to the camp as the army was going out to the fight and shouting for the battle. ²¹ For Israel and the Philistines had drawn up in battle array, army against army. ²² And David left his supplies in the hand of the supply keeper, ran to the army, and came and greeted his brothers.
