This story of Joseph and his brothers through these chapters is very memorable. The story flits back and forth, from Caanan to Egypt to Caanan to Egypt and back to Caanan again.
Joseph, the brother is hidden from his brothers’ sight as he is now probably in Egyptian clothes. His voice is now unrecognizable, as he speaks in another language.
The sounds the characters exchange is thoroughly human, thoroughly ordinary.
Why did you bring this trouble on me by telling the man you had another brother?
(Vs43:6)
Jacob’s complaint is reasonable. Why say more than you need to? There is a consistent sound of bargaining as the brothers negotiate for food and through Joseph’s seemingly strange directives. In the end when Joseph reveals himself and sends them back to fetch his father he says
Don’t quarrel on the way!
(Vs45:24)
Back to their father, Jacob the grasper has had to let go of all that is precious to him. He now has to follow the sound to Egypt.
