Any of you with a skin disease must be brought to a priest.
If he discovers that the sore spot is white with pus and that the hair around it has also turned white,
If sores or boils or a skin rash should break out and start spreading on your body, you must be brought to Aaron or to one of the other priests.
If it is discovered that the disease has started spreading, he will say, "This is leprosy--you are unclean."
