13And the three eldest sons of Jesse went and followed Saul to the battle: and the names of his three sons that went to the battle were Eliab the firstborn, and next unto him Abinadab, and the third Shammah. 14And David was the youngest: and the three eldest followed Saul. 15But David went and returned from Saul to feed his father's sheep at Bethlehem. 16And the Philistine drew near morning and evening, and presented himself forty days.17And 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 to thy brethren; 18And carry these ten cheeses unto the captain of their thousand, and look how thy brethren fare, and take their pledge. 19Now Saul, and they, and all the men of Israel, were in the valley of Elah, fighting with the Philistines.
