Leviticus 14:32-37

³²This is the law for him in whom is the plague of leprosy, and who can’t afford the offerings for his purification.

³³And the Lord spoke to Moses and Aaron, saying,

³⁴Whenever you° shall enter into the land of the Chananites, which I give you for a possession, and I shall put the plague of leprosy in the houses of the land of your possession;

³⁵then the owner of the house shall come and report to the priest, saying, I have seen as it were a plague in the house.

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 afterwards 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.
