Leviticus 14:47

43 If the mildew reappears in the house after the stones have been torn out and the house has been scraped and replastered,

44 the priest must come and inspect it. If the mildew has spread in the house, it is a destructive mildew; the house is unclean.

45 It must be torn down with its stones, its timbers, and all its plaster, and taken outside the city to an unclean place.

46 Anyone who enters the house during any of the days that it is closed up will be unclean until evening.

47 And anyone who sleeps in the house or eats in it must wash his clothes.

48 If, however, the priest comes and inspects it, and the mildew has not spread after the house has been replastered, he shall pronounce the house clean, because the mildew is gone.

49 He is to take two birds, cedar wood, scarlet yarn, and hyssop to purify the house;

50 and he shall slaughter one of the birds over fresh water in a clay pot.

51 Then he shall take the cedar wood, the hyssop, the scarlet yarn, and the live bird, dip them in the blood of the slaughtered bird and the fresh water, and sprinkle the house seven times.
