34 When ye are come into the land of Canaan, which I give to you for a possession, and I put the plague of leprosy in a house of the land of your possession; 35 then he that owneth the house shall come and tell the priest, saying, There seemeth to me to be as it were a plague in the house. 36 And the priest shall command that they empty the house, before the priest goeth in to see the plague, that all that is in the house be not made unclean: and afterward the priest shall go in to see the house: 37 and he shall look on the plague; and, behold, if the plague be in the walls of the house with hollow streaks, greenish or reddish, and the appearance thereof be lower 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 And the priest shall come again the seventh day, and shall look; and, behold, if the plague be spread in the walls of the house; 40 then the priest shall command that they take out the stones in which the plague is, and cast them into an unclean place without the city: 41 and he shall cause the house to be scraped within round about, and they shall pour out the mortar, that they scrape off, without the city into an unclean place: 42 and 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 And if the plague come again, and break out in the house, after that he hath taken out the stones, and after he hath scraped the house, and after it is plastered; 44 then the priest shall come in and look; and, behold, if the plague be spread in the house, it is a fretting leprosy in the house: it is unclean. 45 And he shall break down the house, the stones of it, and the timber thereof, and all the mortar of the house; and he shall carry them forth 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.
