THE LEPROSY OF A HOUSE, AND ITS CLEANSING (Leviticus 14:33-53). The subject of leprosy in houses must be regarded from the same point of view as that of leprosy in clothes. The regulations respecting it are not sanitary laws, as Lange represents them, but rest, as Keil argues, upon an ideal or symbolical basis. The same thought is attached to all species of uncleanness. Something?봧t matters not what?봯roduces a foul and repulsive appearance in the walls of a house. That is in itself sufficient to make that house unclean; for whatever is foul and repulsive is representative of moral and spiritual defilement, and therefore is itself symbolically defiling and defiled. It has been suggested that the special cause of the affection of the houses in Canaan was saltpetre exuding from the materials employed in their building, or iron pyrites in the stone used. This may have been so, or more probably it was the growth of some fungus. Whatever it was, the appearance created by it was so similar to that of leprosy in the human body, as to derive its name from the latter by analogy.
