1 Samuel 17:17-19

17One day Jesse said to his son David, “Take this ephah of roasted grain1 and these ten loaves of bread for your brothers and hurry to their camp. 18Take also these ten portions of cheese to the commander of their unit. Check on the welfare of your brothers and bring back an assurance from them.2 19They are with Saul and all the men of Israel in the Valley of Elah, fighting against the Philistines.”
