39. “On the seventh day the priest must come back and check the house. If the mildew has spread on the walls of the house,
40. then he must order the people to tear out the stones with the mildew on them and throw them away. They must put these stones at a special unclean place outside the city.
41. Then the priest must have the entire house scraped inside. The people must throw away the plaster that was scraped off the walls. They must put that plaster at a special unclean place outside the city.
42. Then new stones must be put in the walls, and the walls must be covered with new plaster.
43. “Maybe someone took away the old stones and plaster and put in new stones and plaster. And maybe mildew again appears in that house.
44. Then the priest must come in and check the house. If the infection has spread in the house, it is a disease that spreads quickly to other places. So the house is unclean.
45. The house must be torn down. All the stones, plaster, and pieces of wood must be taken to the special unclean place outside the city.
46. Anyone who goes into that house will be unclean until evening.
47. Anyone who eats in that house or lies down in there must wash their clothes.
48. “After new stones and plaster are put in a house, the priest must check the house. If the mildew has not spread through the house, the priest will announce that the house is clean, because the mildew is gone.
49. “Then, to make the house clean, the priest must take two birds, a piece of cedar wood, a piece of red cloth, and a hyssop plant.
50. He will kill one bird in a clay bowl over running water.
51. Then he will take the cedar wood, the hyssop, the piece of red cloth, and the living bird and dip them in the blood of the bird that was killed over running water. Then he will sprinkle that blood on the house seven times.
52. In this way he will use these things to make the house clean.
53. He will go to an open field outside the city and let the living bird go free. In this way the priest will make the house pure. The house will be clean.”
54. These are the rules for any infection of leprosy,
