When someone has on the skin a mark, lesion, or blotch which appears to develop into a scaly infection, the person shall be brought to Aaron, the priest, or to one of the priests among his sons.
If the priest, upon examination of the skin’s infection, finds that the hair on the infection has turned white and the infection itself appears to be deeper than the skin, it is indeed a scaly infection; the priest, on seeing this, shall declare the person unclean.
But if, after the person was examined by the priest and declared clean, the scab spreads at all on the skin, the person shall once more be examined by the priest.
Order the Israelites to expel from camp everyone with a scaly infection, and everyone suffering from a discharge, and everyone who has become unclean by contact with a corpse.
