Leviticus 13:5-7

Holman Christian Standard Bible

⁵ The priest will then reexamine him on the seventh day. If he sees that the infection remains unchanged and has not spread on the skin, the priest must quarantine him for another seven days. 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;^(A) 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,^(B) he must present himself again to the priest.
