The priest shall examine him again on the seventh day.
Behold, if the plague has faded and the plague hasn’t spread in the skin, then the priest shall pronounce him clean.
It is a scab.
He shall wash his clothes, and be clean.
But if the scab spreads on the skin after he has shown himself to the priest for his cleansing, he shall show himself to the priest again.
The priest shall examine him; and behold, if the scab has spread on the skin, then the priest shall pronounce him unclean.
It is leprosy.
