Leviticus 13:6-8 ▼

6 The priest will examine him again on the seventh day. If the infection has faded and has not spread on the skin, the priest is to pronounce him clean; it is a scab. The person is to wash his clothes and will become clean.

7 But if the scab spreads further on his skin after he has presented himself to the priest for his cleansing, he must present himself again to the priest.

8 The priest will examine him, and if the scab has spread on the skin, then the priest must pronounce him unclean; he has a skin disease.”
