Leviticus 13:4-6

New American Standard Bible

⁴ But if the bright spot is white on the skin of his ^[a]body, and ^[b]it does not appear to be deeper than the skin, and the hair on it has not turned white, then the priest shall ^[c]isolate the person who has the infection for seven days. ⁵ Then the priest shall look at him on the seventh day, and if in his eyes the infection has ^[d]not changed and the infection has not spread on the skin, then the priest shall ^[e]isolate him for seven more days. ⁶ The priest shall then look at him again on the seventh day, and if the infected area has faded and the infection has not spread on the skin, then the priest shall pronounce him clean; it is only a rash. And he shall ^(A)wash his clothes and be clean.
