34 "When you arrive in Canaan, the land I am giving you as your own possession, I may contaminate some of the houses in your land with mildew. 35 The owner of such a house must then go to the priest and say, 'It appears that my house has some kind of mildew.' 36 Before the priest goes in to inspect the house, he must have the house emptied so nothing inside will be pronounced ceremonially unclean. 37 Then the priest will go in and examine the mildew on the walls. If he finds greenish or reddish streaks and the contamination appears to go deeper than the wall's surface, 38 the priest will step outside the door and put the house in quarantine for seven days. 39 On the seventh day the priest must return for another inspection. If he finds that the mildew on the walls of the house has spread, 40 the priest must order that the stones from those areas be removed. The contaminated material will then be taken outside the town to an area designated as ceremonially unclean. 41 Next the inside walls of the entire house must be scraped thoroughly and the scrapings dumped in the unclean place outside the town. 42 Other stones will be brought in to replace the ones that were removed, and the walls will be replastered. 43 "But if the mildew reappears after all the stones have been replaced and the house has been scraped and replastered, 44 the priest must return and inspect the house again. If he finds that the mildew has spread, the walls are clearly contaminated with a serious mildew, and the house is defiled. 45 It must be torn down, and all its stones, timbers, and plaster must be carried out of town to the place designated as ceremonially unclean.

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.
