Joseph’s identity, hidden from his brothers, was revealed to them in a moment of time, wherein they had a private audience with the Egyptian ruler, who knew them, yet, they did not recognize him. Up until that moment, they had seen him as a cruel ruler, who held authority over them, inasmuch as he could do as he please, by intimidating them, placing them in jail three days, and demanding that they return with their youngest brother. Otherwise, they would not be able to see the ruler, in order to obtain necessary food during the famine; yet, when they finally return, the ruler takes Benjamin as a servant.
After this Judah made an impassioned plea, to take him instead of Benjamin; upon hearing this, Joseph reveals himself to his brothers: “I am Joseph.” Joseph had previously told them, that he fears G-d. No light statement from “an Egyptian ruler;” yet, the brothers may not have accepted this statement as sincere. Now, they see his sincerity demonstrated, inasmuch that he shows them kindness, forgiveness, and mercy, the very qualities valued in Abrahamic legacy. “The fear of the Lord is the beginning of wisdom; a good understanding have all those who do his commandments; his praise endures for ever” (Psalms 111:10, Tanach Bible).
When Jacob arrived in Egypt with his family, his son, Joseph, harnessed his chariot and went out to greet him. Joseph provided for his family to live in the land of Goshen – a land removed from Egypt proper. As a consequence of their living in this location, they were isolated from the rest of Egyptian society. They had more freedom to follow the patriarchal ways of Abraham, Isaac, and Jacob, and foster the character traits that they represented, as opposed to getting caught up in the idolatrous ways, and immorality of their neighbors.
In the midst of the uncertainty, doubt, and fear, that settled in years later, after the children of Israel became enslaved in Egypt, there was the promise of hope in the redeemer. For, before Joseph passed away, he told his brother, pekod pekodti, a redeemer will reveal himself to you. “G-d will surely remember you, and bring you up out of this land unto the land which He swore to Abraham, to Isaac, and to Jacob” (Genesis 50:24).
