A very proper difference is here made between houses in a
   city and houses in the country.  The former might be redeemed
   any time in the course of a year; but after that time could
   not be redeemed, or go out with the Jubilee:  the latter
   might be redeemed at any time; and if not redeemed must go
   out with the jubilee.  The reason in both cases is
   sufficiently evident; the house in the city might be built
   merely for the purposes of trade or traffic--the house in the
   country was builded on, or attached to, the inheritance which
   God had divided to the respective families.  It was therefore
   necessary that the same law should apply to the house as to
   the inheritance; which necessity did not exist with regard to
   the house in the city.  And, as the house in the city might
   be purchased for the purpose of trade, it would be very
   inconvenient for the purchaser, when his business was
   established, to be obliged to remove.
