(43, 45) And if the plague come again.--If after these alterations and precautions the symptoms reappear, the house must be pulled down, just as the garment was destroyed under similar circumstances (see Leviticus 13:51), and the materials deposited in the unclean receptacle outside the city, since its re-appearance shows that it is an incurable leprosy. From the fact that the materials of the house here spoken of are stones, earth, and wood, the ancient canons enacted that no dwelling is exposed to the laws of leprosy unless it has four walls, and is built of stone, earth, and wood. Houses of brick and marble, therefore, do not come within these laws.
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.
after that he hath taken away the stones; which were infected, or ordered them to be taken away:
and after he hath scraped the house; so that there seemed to be no remains of the plague:
and after it is plastered; to prevent if possible any return of it, but in vain.
