23. Yet did not the chief butler remember. This was the most severe trial of Joseph’s patience, as we have before intimated. For since he had obtained an advocate who, without trouble, was able to extricate him from prison, especially as the opportunity of doing so had been granted to him by God, he felt a certain assurance of deliverance, and earnestly waited for it every hour. But when he had remained to the end of the second year in suspense, not only did this hope vanish, but greater despair than ever rested upon his mind. Therefore, we are all taught, in his person, that nothing is more improper, than to prescribe the time in which God shall help us; since he purposely, for a long season, keeps his own people in anxious suspense, that, by this very experiment, they may truly know what it is to trust in Him. Besides, in this manner he designed openly to claim for himself the glory of Joseph’s liberation. For, if liberty had been granted to him through the entreaty of the butler, it would have been generally believed that this benefit was from man and not from God. Moreover, when Moses says, that the butler was forgetful of Joseph, let it be so understood, that he did not dare to make any mention of him, lest he should be subjected to reproach, or should be troublesome to the king himself. For it is common with courtiers perfidiously to betray the innocent, and to deliver them to be slain, rather than to offend those of whom they themselves are afraid.
