Leviticus 14:44-46 New American Standard Bible (NASB)
44 then the priest shall come in and [a]make an inspection. If he sees that the mark has indeed spread in the house, it is a malignant mark in the house; it is unclean. 45 He shall therefore tear down the house, its stones, and its timbers, and all the plaster of the house, and he shall take them outside the city to an unclean place. 46 Moreover, whoever goes into the house during the time that he has [b]quarantined it, becomes unclean until evening.
