Leviticus 14:30-38

³⁰And he shall offer one of the turtle-doves or of the young pigeons, as he can afford it,

³¹the one for a sin-offering, the other for a whole-burnt-offering with the meat-offering, and the priest shall make an atonement before the Lord for him that is under purification.

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

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

³⁴Whensoever ye 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.

³⁸And the priest shall come out of the house to the door of the house, and the priest shall separate the house seven days.
