Leviticus 14:2, 54-57

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

“This is the law for any leprous sore and scale, for the leprosy of a garment and of a house, for a swelling and a scab and a bright spot, to teach when it is unclean and when it is clean. This is the law of leprosy.”
