The priest must order them to clear the house before he enters to examine the contamination, so that nothing in the house becomes unclean. Afterward the priest will come to examine the house.

the owner of the house is to come and tell the priest: Something like mildew contamination has appeared in my house.

the priest is to go outside the house to its doorway and quarantine the house for seven days.

“If the contamination reappears in the house after the stones have been pulled out, and after the house has been scraped and replastered,

the priest must come and examine it. If the contamination has spread in the house, it is harmful mildew; the house is unclean.

“But when the priest comes and examines it, if the contamination has not spread in the house after it was replastered, he is to pronounce the house clean because the contamination has disappeared.
