Leviticus 14:44-57

14:44 the priest is to come and examine it, and if the infection has spread in the house, it is a malignant disease in the house. It is unclean. 14:45 He must tear down the house, its stones, its wood, and all the plaster of the house, and bring all of it outside the city to an unclean place. 14:46 Anyone who enters the house all the days the priest has quarantined it will be unclean until evening. 14:47 Anyone who lies down in the house must wash his clothes. Anyone who eats in the house must wash his clothes.

14:48 “If, however, the priest enters and examines it, and the infection has not spread in the house after the house has been replastered, then the priest is to pronounce the house clean because the infection has been healed. 14:49 Then he is to take two birds, a piece of cedar wood, a scrap of crimson fabric, and some twigs of hyssop to decontaminate the house, 14:50 and he is to slaughter one bird into a clay vessel over fresh water. 14:51 He must then take the piece of cedar wood, the twigs of hyssop, the scrap of crimson fabric, and the live bird, and dip them in the blood of the slaughtered bird and in the fresh water, and sprinkle the house seven times. 14:52 So he is to decontaminate the house with the blood of the bird, the fresh water, the live bird, the piece of cedar wood, the twigs of hyssop, and the scrap of crimson fabric, 14:53 and he is to send the live bird away outside the city into the open countryside. So he is to make atonement for the house and it will be clean.
