Leviticus 13:3-5

Contemporary English Version

³ If the priest 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^[a]—you are unclean.”

⁴ But if the infected area is white and only skin deep, and if the hair in it hasn't turned white, the priest will order you to stay away from everyone else for seven days. ⁵ If the disease hasn't spread by that time, he will order you to stay away from everyone else for another seven days.
