Leviticus 14:33-46

³³Then the Lord told Moses and Aaron,

³⁴“When you get to Canaan, the land I'm giving you to own, if I put some mold into a house there and contaminate it,

³⁵the owner of the house must come and tell the priest, ‘It seems my house has something like mold.’

³⁶The priest must order the house to be emptied before he goes in to inspect the mold, so that nothing in the house will be declared unclean. Once that's done, the priest is to go in and inspect the house.

³⁷He will examine the house and see whether the mold on the walls is made up of green or red indentations that go under the surface,

³⁸the priest shall go out of door and seal the house for seven days.

³⁹On the seventh day the priest will return and inspect the house again. If the mold has spread on the walls,

⁴⁰he will order the affected stones to be removed and disposed of in an unclean area outside the town.

⁴¹Then he will order the all the plaster inside of the house to be scraped off and dumped in an unclean area outside the town.

⁴²Different stones must be used to replace the ones removed, and new plaster will be needed replaster the house.

⁴³If the mold returns and affects the house again even after the stones have been removed and the house has been scraped and replastered,

⁴⁴the priest must come and inspect it. If he sees the mold has spread in the house, it is a harmful mold; the house is unclean.

⁴⁵It must be demolished, and all its stones, timbers, and plaster must be taken and dumped in an unclean area outside the town.

⁴⁶Anyone who goes into the house during any time that it is sealed will be unclean until the evening.
