      Ge 44:1-34. POLICY TO STAY HIS BRETHREN.

      1. And Joseph commanded the steward--The design of putting the cup into the sack of Benjamin was obviously to bring that young man into a situation of difficulty or danger, in order thereby to discover how far the brotherly feelings of the rest would be roused to sympathize with his distress and stimulate their exertions in procuring his deliverance. But for what purpose was the money restored? It was done, in the first instance, from kindly feelings to his father; but another and further design seems to have been the prevention of any injurious impressions as to the character of Benjamin. The discovery of the cup in his possession, if there had been nothing else to judge by, might have fastened a painful suspicion of guilt on the youngest brother; but the sight of the money in each man's sack would lead all to the same conclusion, that Benjamin was just as innocent as themselves, although the additional circumstance of the cup being found in his sack would bring him into greater trouble and danger.
