3. Mose 14:35

When the evil showed itself in a house, the owner was to send this message to the priest, "A leprous evil has appeared in my house," and the priest, before entering to examine it, was to have the house cleared, lest everything in it should become unclean. Consequently, as what was in the house became unclean only when the priest had declared the house affected with leprosy, the reason for the defilement is not to be sought for in physical infection, but must have been of an ideal or symbolical kind.

The former chapter directed the priests how to convict a leper of ceremonial uncleanness. No prescriptions are given for his cure; but, when God had cured him, the priests are in this chapter directed how to cleanse him. The remedy here is only adapted to the ceremonial part of his disease; but the authority Christ gave to his ministers was to cure the lepers, and so to cleanse them. We have here, I. The solemn declaration of the leper's being clean, with the significant ceremony attending it (Lev 14:1-9). II. The sacrifices which he was to offer to God eight days after (v. 10-32). III. The management of a house in which appeared signs of a leprosy (v. 33-53). And the conclusion and summary of this whole matter (Lev 14:54, etc.).
