Leviticus 13:19-21

Contemporary English Version

^18-19 If you have a sore that either swells or turns reddish-white after it has healed, then you must show it to a priest. ²⁰ If he discovers that the hair in the infected area has turned white and that the infection seems more than skin deep, he will say, “This is leprosy—you are unclean.” ²¹ But if the white area is only on the surface of the skin and hasn't become any worse, and if the hair in it hasn't turned white, he will tell you to stay away from everyone else for seven days.
