Many things indeed He ordained hereby; first indeed it rendered the disciples unsuspected; secondly, it held them aloof from all care, so that they might give their whole study to the word; thirdly, it taught them their own proper virtue. But perhaps some one will say that the other things indeed are reasonable, but for what reason did He command them to have no scrip on their way, nor two coats, nor staff? In truth, because He wished to rouse them to all diligence, taking them away from all the cares of this life, that they might be occupied by the one single care of teaching.
