38 Then the priest shall go out of the door and shut up the house seven days.
39 The priest shall come again on the seventh day and shall look; and if the disease has spread in the walls of the house,
40 He shall command that they take out the diseased stones and cast them into an unclean place outside the city.
41 He shall cause the house to be scraped within round about and the plaster or mortar that is scraped off to be emptied out in an unclean place outside the city.
42 And they shall put other stones in the place of those stones, and he shall plaster the house with fresh mortar.
43 If the disease returns, breaking out in the house after he has removed the stones and has scraped and plastered the house,
44 Then the priest shall come and look, and if the disease is spreading in the house, it is a rotting or corroding leprosy in the house; it is unclean.
