1 Samuel 17:17-19

17One day Jesse had told his son David, “Take this half-bushel of roasted grain along with these ten loaves of bread for your brothers and hurry to their camp.

18Also take these ten portions of cheese to the field commander. Check on the well-being of your brothers and bring a confirmation from them.

19They are with Saul and all the men of Israel in the Valley of Elah fighting with the Philistines.”
