Leviticus 13:5–44
On the seventh day the priest is to reexamine him, and if he sees that the infection is unchanged and has not spread on the skin, the priest must isolate him for another seven days. / The priest will examine him again on the seventh day, and if the sore has faded and has not spread on the skin, the priest shall pronounce him clean; it is a rash. The person must wash his clothes and be clean. / But if the rash spreads further on his skin after he has shown himself to the priest for his cleansing, he must present himself again to the priest.
