Joseph is not destroyed even by this experience. He goes on showing Christian character.
Bishop Hall says, ‘No prison would serve him but Pharaoh's. Joseph had lain obscure, and not been known to Pharaoh, if he had not been cast into Pharaoh's dungeon. The afflictions of God's children turn ever to their advantages. No sooner is Joseph a prisoner, than a guardian of the prisoners. Trust and honour accompany him wheresoever he is: in his father's house, in Potiphar's, in the jail, in the court still he hath both favour and rule.’
