1 Samuel 17:17-23

Then Jesse said to David his son, “Take now for your brothers an ephah of this roasted grain and these ten loaves and run to the camp to your brothers. Bring also these ten cuts of cheese to the commander of their thousand, and look into the welfare of your brothers, and bring back news of them. For Saul and they and all the men of Israel are in the valley of Elah, fighting with the Philistines.” So David arose early in the morning and left the flock with a keeper and took the supplies and went as Jesse had commanded him. And he came to the circle of the camp while the army was going out in battle array shouting the war cry. Israel and the Philistines drew up in battle array, army against army. Then David left his baggage in the care of the baggage keeper, and ran to the battle line and entered in order to greet his brothers. As he was talking with them, behold, the champion, the Philistine from Gath named Goliath, was coming up from the army of the Philistines, and he spoke these same words; and David heard them.
