Leviticus 14:43-57

“If the defiling mold reappears in the house after the stones have been torn out and the house scraped and plastered, the priest is to go and examine it and, if the mold has spread in the house, it is a persistent defiling mold; the house is unclean. It must be torn down—its stones, timbers and all the plaster—and taken out of the town to an unclean place. “Anyone who goes into the house while it is closed up will be unclean till evening. Anyone who sleeps or eats in the house must wash their clothes. “But if the priest comes to examine it and the mold has not spread after the house has been plastered, he shall pronounce the house clean, because the defiling mold is gone. To purify the house he is to take two birds and some cedar wood, scarlet yarn and hyssop. He shall kill one of the birds over fresh water in a clay pot. Then he is to take the cedar wood, the hyssop, the scarlet yarn and the live bird, dip them into the blood of the dead bird and the fresh water, and sprinkle the house seven times. He shall purify the house with the bird’s blood, the fresh water, the live bird, the cedar wood, the hyssop and the scarlet yarn. Then he is to release the live bird in the open fields outside the town. In this way he will make atonement for the house, and it will be clean.” These are the regulations for any defiling skin disease, for a sore, for defiling molds in fabric or in a house, and for a swelling, a rash or a shiny spot, to determine when something is clean or unclean. These are the regulations for defiling skin diseases and defiling molds.
