1 Samuel 17:16

¹⁴  And David was the youngest: and the three eldest followed Saul.

¹⁵  But David went and returned from Saul to feed his father's sheep at Bethlehem.

¹⁶  And the Philistine drew near morning and evening, and presented himself forty days.

¹⁷  And Jesse said unto David his son, Take now for thy brethren an ephah of this parched corn, and these ten loaves, and run to the camp of thy brethren;

¹⁸  And carry these ten cheeses unto the captain of their thousand, and look how thy brethren fare, and take their pledge.
