Leviticus 13:6-8

Holman Christian Standard Bible

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. 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.
