Leviticus 14:36-38

21st Century King James Version

³⁶ then the priest shall command that they empty the house before the priest go into it to see the plague, that all that is in the house be not made unclean; and afterward the priest shall go in to see the house.

³⁷ And he shall look on the plague, and behold, if the plague be in the walls of the house with hollow streaks, greenish or reddish, which in appearance are lower than the wall,

³⁸ then the priest shall go out of the house to the door of the house and shut up the house seven days.
