1 Samuel 17:15-20
New International Version
16 For forty days the Philistine came forward every morning and evening and took his stand.
17 Now Jesse said to his son David, “Take this ephah[a](C) of roasted grain(D) and these ten loaves of bread for your brothers and hurry to their camp. 18 Take along these ten cheeses to the commander of their unit. See how your brothers(E) are and bring back some assurance[b] from them. 19 They are with Saul and all the men of Israel in the Valley of Elah, fighting against the Philistines.”
20 Early in the morning David left the flock in the care of a shepherd, loaded up and set out, as Jesse had directed. He reached the camp as the army was going out to its battle positions, shouting the war cry.
