Matthew Henry on Genesis 42:7-20
We may well wonder that Joseph, during the twenty years that he had now been in Egypt, especially during the last seven years that he had been in power there, never sent to his father to acquaint him with his circumstances; nay, it is strange that he who so often went throughout all the land of Egypt (Gen 41:45, Gen 41:46) never made an excursion to Canaan, to visit his aged father, when he was in the borders of Egypt, that lay next to Canaan.
