Leviticus 13:6-8

New American Standard Bible 1995

⁶ The priest shall look at him again on the seventh day, and if the infection has faded and the mark has not spread on the skin, then the priest shall pronounce him clean; it is only a scab. And he shall ^(A)wash his clothes and be clean.

⁷ “But if the scab spreads farther on the skin after he has shown himself to the priest for his cleansing, he shall appear again to the priest. ⁸ The priest shall look, and if the scab has spread on the skin, then the priest shall pronounce him unclean; it is leprosy.
