The Reward of Charity
The Ropshitzer was told that his Master the Rimanover, blessed a man and that the latter was becoming richer every day. He inquired why this man deserved to receive a blessing of such magnitude. The Rimanover replied: "I merely blessed him that he might enjoy a comfortable living. But the man gives away so much to charity that his fortune must be increased abundantly by Heaven so that he may have sufficient for his personal comforts."
