Leviticus 13:32-34

32On the seventh day the priest must examine the sore again. If he finds that the scabby sore has not spread, and there is no yellow hair on it, and it appears to be only skin-deep,

33the person must shave off all hair except the hair on the affected area. Then the priest must quarantine the person for another seven days.

34On the seventh day he will examine the sore again. If it has not spread and appears to be no more than skin-deep, the priest will pronounce the person ceremonially clean. The person’s clothing must be washed, and the person will be ceremonially clean.
