Leviticus 14:2, 54-57

“This shall be the law of the leprous person for the day of his cleansing. He shall be brought to the priest

This is the law for any case of leprous disease: for an itch, for leprous disease in a garment or in a house, and for a swelling or an eruption or a spot, to show when it is unclean and when it is clean. This is the law for leprous disease.
