Leviticus 14:34-38

34"When you come into the land of Canaan, which I give you for a possession, and I put a case of leprous disease in a house in the land of your possession,

35then he who owns the house shall come and tell the priest, 'There seems to me to be some case of disease in my house.'

36Then the priest shall command that they empty the house before the priest goes to examine the disease, lest all that is in the house be declared unclean. And afterward the priest shall go in to see the house.

37And he shall examine the disease. And if the disease is in the walls of the house with greenish or reddish spots, and if it appears to be deeper than the surface,

38then the priest shall go out of the house to the door of the house and shut up the house seven days.
