Leviticus 14:30-38

³⁰And he shall offer one of the turtle-doves, or of the young pigeons, such as his means suffice for;

³¹even such as his means suffice for, the one for a sin-offering, and the other for a burnt-offering, with the meal-offering; and the priest shall make atonement for him that is to be cleansed before the LORD.

³²This is the law of him in whom is the plague of leprosy, whose means suffice not for that which pertaineth to his cleansing.

³³And the LORD spoke unto Moses and unto Aaron, saying:

³⁴When ye are come into the land of Canaan, which I give to you for a possession, and I put the plague of leprosy in a house of the land of your possession;

³⁵then he that owneth the house shall come and tell the priest, saying: 'There seemeth to me to be as it were a plague in the house.'

³⁶And the priest shall command that they empty the house, before the priest go in 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.

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

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