1 Samuel 25:4-5

Though David had gone some distance southward of Carmel, yet it was worth his while to send men to Nabal's sheep shearing, as the maintenance of his numerous force must have been a continual difficulty. The large number, ten , also shows that he expected a liberal gift of food. Probably such missions were not uncommon, and the large sheep masters were glad to supply the wants of one who guarded their flocks and defended them from the incursions of the desert tribes.
