Leviticus 13:19-21 New Life Version (NLV)
19 and in the place of the sore there is a white, growing spot or a light-red, bright spot, it must be shown to the religious leader. 20 If the religious leader finds that it is under the skin and that the hair on it has become white, the religious leader will say he is unclean. It is the bad skin disease. It has broken out in the sore. 21 But the religious leader may find there are no white hairs in it, and that it is not under the skin and not as dark. Then the religious leader will keep him away from other people for seven days.
