29 If you have a sore on your head or chin,
30 it must be examined by a priest. If the infection seems more than skin deep, and the hair in it has thinned out and lost its colour, he will say, “This is leprosy—you are unclean.”
31 On the other hand, if he discovers that the itchy spot is only skin deep, but that the hair still isn't healthy, he will order you to stay away from everyone else for seven days.
32 By that time, if the itch hasn't spread, if the hairs seem healthy, and if the itch is only skin deep,
33 you must shave off the hairs around the infection, but not those on it. Then the priest will tell you to stay away from everyone else for another seven days.
34 By that time, if the itch hasn't spread and seems no more than skin deep, he will say, “You are clean; now you must wash your clothes.”
35-36 Later, if the itch starts spreading, even though the hair is still healthy, the priest will say, “You are unclean.”
