Leviticus 14:33

The law concerning the leprosy of houses was made known to Moses and Aaron, as intended for the time when Israel should have taken possession of Canaan and dwell in houses. As it was Jehovah who gave His people the land for a possession, so "putting the plague of leprosy in a house of the land of their possession" is also ascribed to Him (Lev 14:34), inasmuch as He held it over them, to remind the inhabitants of the house that they owed not only their bodies but also their dwelling-places to the Lord, and that they were to sanctify these to Him. By this expression, "I put," the view which Knobel still regards as probable, viz., that the house-leprosy was only the transmission of human leprosy to the walls of the houses, is completely overthrown; not to mention the fact, that throughout the whole description there is not the slightest hint of any such transmission, but the inhabitants, on the contrary, are spoken of as clean, i.e., free from leprosy, and only those who went into the house, or slept in the house after it had been shut up as suspicious, are pronounced unclean (Lev 14:46, Lev 14:47), though even they are not said to have been affected with leprosy. The only thing that can be gathered from the signs mentioned in Lev 14:37 is, that the house-leprosy was an evil which calls to mind "the vegetable formations and braid-like structures that are found on mouldering walls and decaying walls, and which eat into them so as to produce a slight depression in the surface." (Note: Cf. Sommer (p. 220), who says, "The crust of many of these lichens is so marvellously thin, that they simply appear as coloured spots, for the most part circular, which gradually spread in a concentric form, and can be rubbed off like dust. Some species have a striking resemblance to eruptions…

This is the law concerning the leprosy in a house. Now that they were in the wilderness they dwelt in tents, and had no houses, and therefore the law is made only an appendix to the former laws concerning the leprosy, because it related, not to their present state, but to their future settlement. The leprosy in a house is as unaccountable as the leprosy in a garment; but, if we see not what natural causes of it can be assigned, we may resolve it into the power of the God of nature, who here says, I put the leprosy in a house (Lev 14:34), as his curse is said to enter into a house, and consume it with the timber and stones thereof, Zac 5:4. Now, 1. It is supposed that even in Canaan itself, the land of promise, their houses might be infected with a leprosy. Though it was a holy land, this would not secure them from this plague, while the inhabitants were many of them so unholy. Thus a place and a name in the visible church will not secure wicked people from God's judgments. 2. It is likewise taken for granted that the owner of the house will make the priest acquainted with it, as soon as he sees the least cause to suspect the leprosy in his house: It seemeth to me there is as it were a plague in the house, Lev 14:35. Sin, where that reigns in a house, is a plague there, as it is in a heart. And masters of families should be aware and afraid of the first appearance of gross sin in their families, and put away the iniquity, whatever it is, far from their tabernacles, Job 22:23. They should be jealous with a godly jealousy concerning those under their charge, lest they be drawn into sin, and take early advice, if it but seem that there is a plague in the house, lest the contagion spread, and many be by it defiled and destroyed. 3. If the priest, upon search, found that the…

14:33-53 The contamination of buildings by rot or mildew made them unhealthy or even unsafe. These buildings were considered diseased and therefore not whole or clean (see study note on 11:1–15:33). The inspection and treatment process was similar to the one for mildew in clothing (13:47-59).
