Charles H. Spurgeon on Psalms 15:5

The rich make the poor to fill them; for usurers feed upon the poor, even as great fishes devour the small. Therefore, he which said, Let there not be a beggar in Israel (Deuteronomy 15:4), said too, Let there not be an usurer in Israel. For if there be usurers in Israel there will be beggars in Israel; for usurers make beggars, even as lawyers make quarrellers. . . . . It is a miserable occupation to live by sin, and a great comfort to a man when he looketh upon his gold and silver, and his heart telleth him, All this is well gotten; and when he lieth upon his death-bed, and must leave all to his children, he can say unto them, I leave you mine own; but the usurer cannot say, I leave you mine own, but I leave you other men's; therefore the usurer can never die in peace, because if he die before he maketh restitution, he dieth in his sin. Henry Smith.
