Leviticus 14:33-57 - Instructions For Cleansing Houses
33 Jehovah spoke to Moses and Aaron: 34 When you come to Canaan that I am going to give to you, mildew may appear in a house. 35 The owner of that house must come and tell the priest that there is something that looks like mildew in his house. 36 Before the priest examines the house, he will order everything taken out of it so that nothing in the house will become unclean. Then the priest will go inside to examine the house. 37 He will examine the mildew area on the walls. If it is green and red in sunken areas that are deeper than the rest of the wall, 38 the priest will go out to the door of the house and close up the house for seven days. 39 The priest will go back and examine it again on the seventh day. If the mildew in the walls of the house has spread, 40 he must order the stones that have the mildew to be torn out and thrown outside the city in an unclean place. 41 He must have the entire inside of the house scraped. The plaster dust scraped off the walls must be dumped in an unclean place outside the city. 42 The stones must be replaced, and the house must be plastered again.
43 If the mildew breaks out again in the house after the stones have been removed and the house has been scraped and plastered, 44 the priest will go and look. If it has spread, the house is unclean. 45 It must be torn down, and its stones, its wood, and all its plaster must be carried out of the city to an unclean place. 46 Whoever goes into the house during the time that he has quarantined it, becomes unclean until evening. 47 Whoever lies down in the house must wash his clothes, and whoever eats in the house must wash his clothes.
48 If the mildew has not reappeared after the house has been replastered, the priest will pronounce the house ritually clean. This is because the mildew has been completely removed. 49 He shall take two birds, some cedar wood, a red cord, and a sprig of hyssop to purify the house. 50 He should kill one of the birds over a clay bowl containing fresh spring water. 51 Then he will take the cedar wood, the hyssop, the red cord, and the live bird and dip them in the blood of the bird that was killed and in the fresh water. He will sprinkle the house seven times. 52 This is the way he will purify the house with the bird's blood, the fresh water, the live bird, the cedar wood, the hyssop, and the red cord. 53 Then the priest will let the living bird fly from the city into the open country. He will pay compensation for wrongdoing and make peace with Jehovah for the house. It will be clean.
54 These are the instructions for any kind of mildew or fungus 55 that infects clothing or houses 56 and for skin diseases where there is a sore, a rash, or an irritated area. 57 These instructions for skin diseases and mildew help you distinguish between what is clean and unclean.
