1 Samuel 17:20-22

King James Version

²⁰ And David rose up early in the morning, and left the sheep with a keeper, and took, and went, as Jesse had commanded him; and he came to the trench, as the host was going forth to the fight, and shouted for the battle.

²¹ For Israel and the Philistines had put the battle in array, army against army.

²² And David left his carriage in the hand of the keeper of the carriage, and ran into the army, and came and saluted his brethren.
