Leviticus 14:34-38

34“When you enter the land of Canaan which I am about to give to you for a possession, and I put a diseased infection in a house in the land you are to possess,

35then whoever owns the house must come and declare to the priest, ‘Something like an infection is visible to me in the house.’

36Then the priest will command that the house be cleared before the priest enters to examine the infection so that everything in the house does not become unclean, and afterward the priest will enter to examine the house.

37He is to examine the infection, and if the infection in the walls of the house consists of yellowish green or reddish eruptions, and it appears to be deeper than the surface of the wall,

38then the priest is to go out of the house to the doorway of the house and quarantine the house for seven days.
