34 “When you have come into the land of Canaan, which I give to you for a possession, and I put a spreading mildew in a house in the land of your possession, 35 then he who owns the house shall come and tell the priest, saying, ‘There seems to me to be some sort of plague in the house.’ 36 The priest shall command that they empty the house, before the priest goes in to examine the plague, that all that is in the house not be made unclean: and afterward the priest shall go in to inspect the house. 37 He shall examine the plague; and behold, if the plague is in the walls of the house with hollow streaks, greenish or reddish, and it appears to be deeper than the wall; 38 then the priest shall go out of the house to the door of the house, and shut up the house seven days. 39 The priest shall come again on the seventh day, and look. If the plague has spread in the walls of the house, 40 then the priest shall command that they take out the stones in which is the plague, and cast them into an unclean place outside of the city: 41 and he shall cause the inside of the house to be scraped all over, and they shall pour out the mortar, that they scraped off, outside of the city into an unclean place. 42 They shall take other stones, and put them in the place of those stones; and he shall take other mortar, and shall plaster the house. 43 “If the plague comes again, and breaks out in the house, after he has taken out the stones, and after he has scraped the house, and after it was plastered; 44 then the priest shall come in and look; and behold, if the plague has spread in the house, it is a destructive mildew in the house. It is unclean. 45 He shall break down the house, its stones, and its timber, and all the house’s mortar. He shall carry them out of the city into 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.
