Leviticus 13:20

¹⁸And if the flesh should have become an ulcer in his skin, and should be healed,

¹⁹and there should be in the place of the ulcer a white sore, or one looking white and bright, or fiery, and it shall be seen by the priest;

— Leviticus 13:20 —

²¹But if the priest look, and behold there is no white hair on it, and it be not below the skin of the flesh, and it be dark-colored; then the priest shall separate him seven days.

²²But if it manifestly spread over the skin, then the priest shall pronounce him unclean: it is a plague of leprosy; it has broken out in the ulcer.
