Joseph said to his brothers “I am Joseph, is my father still alive?” but his brothers were unable to answer him, because they were shocked by his face.” There is a tradition that in his physical appearance, Joseph resembled his father Jacob. Seeing that his brothers did not recognize him, Joseph wondered if he had drifted so far from his old life that he’d lost even the most obvious resemblance between himself and their father. But it was not so and as soon as he revealed himself to his brothers, they saw the resemblance and “were shocked by his face.” Sometimes the obvious is staring us in the face but because of our own preconceived ideas we fail to see it clearly,as the Midrash teaches “all are blind, until God opens their eyes.”
