1 Samuel 17:20-21

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. {trench: or, place of the carriage} {fight: or, battle array, or, place of fight} For Israel and the Philistines had put the battle in array, army against army.
