34 "When you have come into the land of Canaan, which I give you as a possession, and I put the leprous plague in a house in the land of your possession, 35 and he who owns the house comes and tells the priest, saying, 'It seems to me that there is some plague in the house,' 36 then the priest shall command that they empty the house, before the priest goes into it to examine the plague, that all that is in the house may not be made unclean; and afterward the priest shall go in to examine the house. 37 And he shall examine the plague; and indeed if the plague is on the walls of the house with ingrained streaks, greenish or reddish, which appear to be deep in 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 And the priest shall come again on the seventh day and look; and indeed if the plague has spread on the walls of the house, 40 then the priest shall command that they take away the stones in which is the plague, and they shall cast them into an unclean place outside the city. 41 And he shall cause the house to be scraped inside, all around, and the dust that they scrape off they shall pour out in 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 mortar and plaster the house. 43 "Now if the plague comes back and breaks out in the house, after he has taken away the stones, after he has scraped the house, and after it is plastered, 44 then the priest shall come and look; and indeed if the plague has spread in the house, it is an active leprosy in the house. It is unclean. 45 And he shall break down the house, its stones, its timber, and all the plaster of the house, and he shall carry them outside 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.
