When our Lord says, Give to the poor, it becomes a man no longer to be careless, but diligently to dispose of all things, first of all by himself if in any measure he is able, if not, by those who are known to be faithful, and prudent in their management; for cursed is he who doeth the work of the Lord negligently. (Jerem. 49, 10.)
