When Joseph's brothers return to Egypt to buy grain they bring Benjamin, a stipulation by "the man." When Joseph's silver cup is planted in Benjamin's sack and "discovered," Judah steps up to plead for the lad since he had become surety for him to his father Jacob. This is too much for Joseph, and he breaks down in tears as he reveals himself, telling his brothers that God has been behind it all in order to save them during the famine. Since both shepherds and Hebrews were loathsome to Egyptians, how else could God have them sheltered there except by having a Hebrew over the whole land?
