Leviticus 14:34-38

34“1When 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,

35then the one who owns the house shall come and tell the priest, saying, ‘Something like 2a spot of leprosy has become visible to me in the house.’

36The 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.

37So he shall look at the spot, and if the spot on the walls of the house has greenish or reddish depressions and appears deeper than the 3surface,

38the priest shall come out of the house, to the 4doorway, and 5quarantine the house for seven days.
