Leviticus 14:30-38

³⁰Then they must sacrifice one of the turtledoves or young pigeons, whichever they can afford,

³¹one as a sin offering and the other as a burnt offering, along with the grain offering. This is how the priest will make the person right and clean before the Lord.

³²These are the regulations for those who have a skin disease and can't afford the usual offerings to make people clean.”

³³Then the Lord told Moses and Aaron,

³⁴“When you get to Canaan, the land I'm giving you to own, if I put some mold into a house there and contaminate it,

³⁵the owner of the house must come and tell the priest, ‘It seems my house has something like mold.’

³⁶The priest must order the house to be emptied before he goes in to inspect the mold, so that nothing in the house will be declared unclean. Once that's done, the priest is to go in and inspect the house.

³⁷He will examine the house and see whether the mold on the walls is made up of green or red indentations that go under the surface,

³⁸the priest shall go out of door and seal the house for seven days.
