When all preparations for the burial of Jacob had been completed, Joseph asked permission of Pharaoh to carry the body up into Canaan. But he did not himself go to put his petition before Pharaoh, for he could not well appear before the king in the garb of a mourner, nor was he willing to interrupt his lamentation over his father for even a brief space and stand before Pharaoh and prefer his petition. He requested the family of Pharaoh to intercede for him with the king for the additional reason that he was desirous of enlisting the favor of the king's relations, lest they advise Pharaoh not to fulfil his wish. He acted according to the maxim, "Seek to win over the accuser, that he cause thee no annoyance."
