and the priest shall examine him the seventh day; if it is spreading in the skin, then the priest shall pronounce him unclean; it is a leprous disease.
the priest shall examine the disease; and if it appears deeper than the skin, and the hair in it is yellow and thin, then the priest shall pronounce him unclean; it is an itch, a leprosy of the head or the beard.
and on the seventh day the priest shall examine the itch, and if the itch has not spread in the skin and it appears to be no deeper than the skin, then the priest shall pronounce him clean; and he shall wash his clothes, and be clean.
