Leviticus 14:34-38

34“When you come into the land of Canaan, which I am giving you as a possession, and I put a mark of leprosy on a house in your land,

35then the one who owns the house shall come and tell the priest, ‘I have seen something that looks like a mark of leprosy in my house.’

36The priest shall order that they empty the house before he goes in to examine the mark, so that everything in the house will not have to be declared unclean; afterward he shall go in to see the house.

37He shall examine the mark, and if the mark on the walls of the house has greenish or reddish depressions and appears deeper than the surface,

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