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 leprosy had got into the house, he must try to cure it, by taking gout that part of the building that was infected, Lev 14:40, Lev 14:41. This was like cutting off a gangrened limb, for the preservation of the rest of the body. Corruption should be purged out in time, before it spread; for a little leaven leaveneth the whole lump. If thy right hand offend thee, cut it off. 4. If yet it remained in the house, the whole house must be pulled down, and all the materials carried to the dunghill, Lev 14:44, Lev 14:45. The owner had better be without a dwelling than live in one that was infected. Note, The leprosy of sin, if it be obstinate under the methods of cure, will at last be the ruin of families and churches. If Babylon will not be healed, she shall be forsaken and abandoned, and (according to the law respecting the leprous house), they shall not take of her a stone for a corner, nor a stone for foundations, Jer 51:9, Jer 51:26. The remainders of sin and corruption in our mortal bodies are like this leprosy in the house; after all our pains in scraping and plastering, we shall never be quite clear of it, till the earthly house of this tabernacle be dissolved and taken down; when we are dead we shall be free from sin, and not till then, Rom 6:7. 5. If the taking out the infected stones cured the house, and the leprosy did not spread any further, then the house must be cleansed; not only aired, that it might be healthful, but purified from the ceremonial pollution, that it might be fit to be the habitation of an Israelite. The ceremony of its cleansing was much the same with that of cleansing a leprous person, Lev 14:49, etc. This intimated that the house was smitten for the man's sake (as bishop Patrick expresses it), and he was to look upon himself as preserved by divine mercy. The houses of Israelites are said to be dedicated (Deu 20:5), for they were a holy nation, and therefore they ought to keep their houses pure from all ceremonial pollutions, that they might be fit for the service of that God to whom they were devoted. And the same care should we take to reform whatever is amiss in our families, that we and our houses may serve the Lord; see Gen 35:2. Some have thought the leprosy in the house was typical of the idolatry of the Jewish church, which did strangely cleave to it; for, though some of the reforming kings took away the infected stones, yet still it broke out again, till by the captivity of Babylon God took down the house, and carried it to an unclean land; and this proved an effectual cure of their inclination to idols and idolatrous worships.

He shall break down the house - "On the suspicion of a house being infected, the priest examined it, and ordered it to be shut up seven days; if he found the plague, or signs of the plague, (hollow streaks, greenish or reddish), were not spread, he commanded it to be shut up seven days more. On the thirteenth day he revisited it; and if he found the infected place dim, or gone away, he took out that part of the wall, carried it out to an unclean place, mended the wall, and caused the whole house to be new plastered. It was then shut up a third seven days, and he came on the nineteenth, and if he found that the plague was broken out anew, he ordered the house to be pulled down." See Ainsworth. From all this may we not learn a lesson of instruction? If the means made use of by God and his ministers for the conversion of a sinner be, through his willful obstinacy, rendered of no avail; if by his evil practices he trample under foot the blood of the covenant wherewith he might have been sanctified, and do despite to the Spirit of God; then God will pull down his house - dislodge his soul from its earthly tabernacle, consign the house, the body, to corruption, and the spirit to the perdition of ungodly men. Reader, see well how it stands with thy soul. God is not mocked: what a man soweth, that shall he reap.

And he shall take to cleanse the house,.... The priest, or by his fellow priest, as Aben Ezra, though some interpret it of the master of the house; in Lev 14:49, an account is given of the manner of cleansing a leprous house, which is the same with that of cleansing a leprous man, see notes on Lev 14:4-7,

Two birds. The birds here indeed are not described as "alive and clean", Lev 14:4; but both are plainly implied and the house is said to be cleansed with the blood of the slain bird, as well as with the living bird; and it was the upper door post of the house which was sprinkled seven times with it, but there were no sacrifices offered; in this case, as in the cleansing of the leper, the atonement for it was made by the other rites, which were sufficient to render it habitable again, and free for use, either of the owner or any other person:

and cedar wood, and scarlet, and hyssop. See Gill on Lev 14:4.

leprosy in a house--This law was prospective, not to come into operation till the settlement of the Israelites in Canaan. The words, "I put the leprosy," has led many to think that this plague was a judicial infliction from heaven for the sins of the owner; while others do not regard it in this light, it being common in Scripture to represent God as doing that which He only permits in His providence to be done. Assuming it to have been a natural disease, a new difficulty arises as to whether we are to consider that the house had become infected by the contagion of leprous occupiers; or that the leprosy was in the house itself. It is evident that the latter was the true state of the case, from the furniture being removed out of it on the first suspicion of disease on the walls. Some have supposed that the name of leprosy was analogically applied to it by the Hebrews, as we speak of cancer in trees when they exhibit corrosive effects similar to what the disease so named produces on the human body; while others have pronounced it a mural efflorescence or species of mildew on the wall apt to be produced in very damp situations, and which was followed by effects so injurious to health as well as to the stability of a house, particularly in warm countries, as to demand the attention of a legislator. Moses enjoined the priests to follow the same course and during the same period of time for ascertaining the true character of this disease as in human leprosy. If found leprous, the infected parts were to be removed. If afterwards there appeared a risk of the contagion spreading, the house was to be destroyed altogether and the materials removed to a distance. The stones were probably rough, unhewn stones, built up without cement in the manner now frequently used in fences and plastered over, or else laid in mortar. The oldest examples of architecture are of this character. The very same thing has to be done still with houses infected with mural salt. The stones covered with the nitrous incrustation must be removed, and if the infected wall is suffered to remain, it must be plastered all over anew.
