1 Samuel 17:16-19

17:16 Meanwhile for forty days the Philistine approached every morning and evening and took his position. 17:17 Jesse said to his son David, “Take your brothers this ephah of roasted grain and these ten loaves of bread; go quickly to the camp to your brothers. 17:18 Also take these ten portions of cheese to their commanding officer. Find out how your brothers are doing and bring back their pledge that they received the goods. 17:19 They are with Saul and the whole Israelite army in the valley of Elah, fighting with the Philistines.”
