Leviticus 14:46-48

New Revised Standard Version, Anglicised Catholic Edition

⁴⁶ All who enter the house while it is shut up shall be unclean until the evening; ⁴⁷ and all who sleep in the house shall wash their clothes; and all who eat in the house shall wash their clothes.

⁴⁸ If the priest comes and makes an inspection, and the disease has not spread in the house after the house was plastered, the priest shall pronounce the house clean; the disease is healed.
