Leviticus 14:2, 54-57

“This shall be the law of the leper in the day of his cleansing. Now he shall be brought to the priest

This is the law for any mark of leprosy—even for a scale, and for the leprous garment or house, and for a swelling, and for a scab, and for a bright spot— to teach when they are unclean and when they are clean. This is the law of leprosy.
