Leviticus 14:32-36

This is the law for him in whom there is an infection of leprosy, whose means are limited for his cleansing.” Cleansing a Leprous House

The Lord further spoke to Moses and to Aaron, saying:

“When you enter the land of Canaan, which I am giving you as a possession, and I put a spot of leprosy on a house in the land of your possession,

then the one who owns the house shall come and tell the priest, saying, ‘Something like a spot of leprosy has become visible to me in the house.’

The priest shall then command that they empty the house before the priest goes in to look at the spot, so that everything in the house need not become unclean; and afterward the priest shall go in to look at the house.
