The test which revealed the thoroughness of his brothers' repentance was unintentionally applied by Joseph. When he hid his cup in Benjamin's sack, all that he intended was to furnish a pretext for detaining Benjamin, and so gratifying his own affection. But, to his astonishment, his trick effected far more than he intended; for the brothers, recognising now their brotherhood, circled round Benjamin, and, to a man, resolved to go back with him to Egypt. We cannot argue from this that Joseph had misapprehended the state of mind in which his brothers were, and in his judgment of them had been either too timorous or too severe; nor need we suppose that he was hampered by his relations to Pharaoh, and therefore unwilling to connect himself too closely with men of whom he might be safer to be rid; because it was this very peril of Benjamin's that matured their brotherly affection. They themselves could not have anticipated that they would make such a sacrifice for Benjamin. But throughout their dealings with this mysterious Egyptian, they felt themselves under a spell, and were being gradually, though perhaps unconsciously, softened, and in order to complete the change passing upon them, they but required some such incident as this of Benjamin's arrest. This incident seemed by some strange fatality to threaten them with a renewed perpetration of the very crime they had committed against Rachel's other son. It threatened to force them to become again the instrument of bereaving their father of his darling child, and bringing about that very calamity which they had pledged themselves should never happen. It was an incident, therefore, which, more than any other, was likely to call out their family love.
