1 Samuel 17:19-21

King James Version

¹⁹ Now Saul, and they, and all the men of Israel, were in the valley of Elah, fighting with the Philistines.

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.
