Leviticus 14:47-49

New Catholic Bible

⁴⁷ He who lies down in the house shall wash his clothes, and he who eats in the house shall wash his clothes.

⁴⁸ “But if the priest comes and examines it, and the infection in the house has not spread after it has been replastered, then the priest shall declare it to be clean, for the infection has been cured. ⁴⁹ He shall obtain two birds, cedar wood, scarlet yarn, and hyssop to ritually purify the house.
