We Cannot Atone

I've often wondered what Potiphar and his wife may have thought once Joseph became second in command (if they were still alive by that point). I'm quite sure they must have been shaking in their shoes fearing some sort of retribution by Joseph for how badly they had treated him. Yet, the situation is really never mentioned again nor does it appear that Joseph nurtured any sort of resentment in his heart toward them. The fact that years later, he could so fully forgive his own brothers for the part they played in selling him into slavery tells us that Joseph was a man of mercy and truth. This is exactly why Joseph is a type of Christ in Scripture.
