Thus it shows that the butler had been so deeply impressed with the pure character of Prophet Joseph that even years had failed to blot it from his heart.

*40) That is, "They might understand your true worth and realize their own error in keeping you in prison without any just cause. And in a way I may get the opportunity of fulfilling the promise I made with you during my imprisonment. "
