Leviticus 14:46

⁴⁴then the priest shall go in and see if the plague is spread in the house: it is a confirmed leprosy in the house, it is unclean.

⁴⁵And they shall take down the house, and its timbers and its stones, and they shall carry out all the mortar without the city into an unclean place.

— Leviticus 14:46 —

⁴⁷And he that sleeps in the house shall wash his garments, and be unclean until evening; and he that eats in the house shall wash his garments, and be unclean until evening.

⁴⁸And if the priest shall arrive and enter and see, and behold the plague be not at all spread in the house after the house has been plastered, then the priest shall declare the house clean, because the plague is healed.
