1 Samuel 17:16-24

And the Philistine drew near morning and evening, and presented himself forty days. And Jesse said unto David his son, Take now for thy brethren an ephah of this parched grain, and these ten loaves, and carry them quickly to the camp to thy brethren; and bring these ten cheeses unto the captain of their thousand, and look how thy brethren fare, and take their pledge. Now Saul, and they, and all the men of Israel, were in the vale of Elah, fighting with the Philistines. 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 place of the wagons, as the host which was going forth to the fight shouted for the battle. And Israel and the Philistines put the battle in array, army against army. And David left his baggage in the hand of the keeper of the baggage, and ran to the army, and came and saluted his brethren. And as he talked with them, behold, there came up the champion, the Philistine of Gath, Goliath by name, out of the ranks of the Philistines, and spake according to the same words: and David heard them. And all the men of Israel, when they saw the man, fled from him, and were sore afraid.
