Leviticus 14:36-38

The Voice

³⁶ The priest must then order the person to remove all the contents from the house before he comes to examine the spot. This saves the person from possibly having everything in the house declared unclean. After this is done, the priest can go inside and inspect the spot. ³⁷ If he sees that the spot has greenish or reddish depressions and appears to go deep beneath the surface of the wall, ³⁸ then the priest will exit the house through the door and quarantine the house for seven days.
