After Samuel privately anointed Saul as ruler over Israel, he gave him a series of signs that would confirm what had happened.
The first sign was to occur near Rachel's tomb in the territory of Benjamin at Zelzah. Saul would meet two men who would report that the lost donkeys had been found and that his father Kish was now concerned about his son.
The episode connects Zelzah with the beginning of Israel's monarchy and with Saul's transition from searching for his father's animals to discovering that he had been chosen for kingship.
