“When you enter the land of Canaan, which I am giving you as your possession, and I put a spreading mold in a house in that land,
the owner of the house must go and tell the priest, ‘I have seen something that looks like a defiling mold in my house.’
The priest is to order the house to be emptied before he goes in to examine the mold, so that nothing in the house will be pronounced unclean. After this the priest is to go in and inspect the house.
He is to examine the mold on the walls, and if it has greenish or reddish depressions that appear to be deeper than the surface of the wall,
the priest shall go out the doorway of the house and close it up for seven days.
On the seventh day the priest shall return to inspect the house. If the mold has spread on the walls,
he is to order that the contaminated stones be torn out and thrown into an unclean place outside the town.
He must have all the inside walls of the house scraped and the material that is scraped off dumped into an unclean place outside the town.
Then they are to take other stones to replace these and take new clay and plaster the house.
“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.
