Leviticus 14:38

³⁶And the priest shall give orders to remove the furniture of the house, before the priest comes in to see the plague, and thus none of the things in the house shall become unclean; and afterward the priest shall go in to examine the house.

³⁷And he shall look on the plague, and, behold, if the plague is in the walls of the house, he will see greenish or reddish cavities, and the appearance of them will be beneath the surface of the walls.

— Leviticus 14:38 —

³⁹And the priest shall return on the seventh day and view the house; and, behold, if the plague is spread in the walls of the house,

⁴⁰then the priest shall give orders, and they shall take away the stones in which the plague is, and shall cast them out of the city into an unclean place.
