34 "When you come into the land of Canaan, which I give you for a possession, and I put a leprous disease in a house in the land of your possession, 35 then he who owns the house shall come and tell the priest, 'There seems to me to be some sort of disease in my house.' 36 Then the priest shall command that they empty the house before the priest goes to examine the disease, lest all that is in the house be declared unclean; and afterward the priest shall go in to see the house. 37 And he shall examine the disease; and if the disease is in the walls of the house with greenish or reddish spots, and if it appears to be deeper than the surface, 38 then the priest shall go out of the house to the door of the house, and shut up the house seven days. 39 And the priest shall come again on the seventh day, and look; and if the disease has spread in the walls of the house, 40 then the priest shall command that they take out the stones in which is the disease and throw them into an unclean place outside the city; 41 and he shall cause the inside of the house to be scraped round about, and the plaster that they scrape off they shall pour into an unclean place outside the city; 42 then they shall take other stones and put them in the place of those stones, and he shall take other plaster and plaster the house. 43 "If the disease breaks out again in the house, after he has taken out the stones and scraped the house and plastered it, 44 then the priest shall go and look; and if the disease has spread in the house, it is a malignant leprosy in the house; it is unclean. 45 And he shall break down the house, its stones and timber and all the plaster of the house; and he shall carry them forth out of the city to an unclean place.

Commentary on Leviticus 14:33-53
(Read Leviticus 14:33-53)
The leprosy in a house is unaccountable to us, as well as the leprosy in a garment; but now sin, where that reigns in a house, is a plague there, as it is in a heart. Masters of families should be aware, and afraid of the first appearance of sin in their families, and put it away, whatever it is. If the leprosy is got into the house, the infected part must be taken out. If it remain in the house, the whole must be pulled down. The owner had better be without a dwelling, than live in one that was infected. The leprosy of sin ruins families and churches. Thus sin is so interwoven with the human body, that it must be taken down by death.
