Interest.

And another came, saying, Lord, behold, here is thy pound, which I have kept laid up in a napkin: for I feared thee, because thou art an austere man: thou takest up that thou layedst not down, and reapest that thou didst not sow. And he saith unto him, Out of thine own mouth will I judge thee, thou wicked servant. Thou knewest that I was an austere man, taking up that I laid not down, and reaping that I did not sow: wherefore then gavest not thou my money into the bank, that at my coming I might have required mine own with USURY? ( Luke 19:20-23 )
