Leviticus 13:5-6
13:5 The priest must then examine it on the seventh day, and if, as far as he can see, the infection has stayed the same and has not spread on the skin, then the priest is to quarantine the person for another seven days.
13:6 The priest must then examine it again on the seventh day, and if the infection has faded and has not spread on the skin, then the priest is to pronounce the person clean. It is a scab, so he must wash his clothes and be clean.
Leviticus 13:20
13:20 The priest will then examine it, and if it appears to be deeper than the skin and its hair has turned white, then the priest is to pronounce the person unclean. It is a diseased infection that has broken out in the boil.
Leviticus 13:25
13:25 the priest must examine it, and if the hair has turned white in the bright spot and it appears to be deeper than the skin, it is a disease that has broken out in the burn. The priest is to pronounce the person unclean. It is a diseased infection.
Leviticus 13:28
13:28 But if the bright spot stays in its place, has not spread on the skin, and it has faded, then it is the swelling of the burn, so the priest is to pronounce him clean, because it is the scar of the burn.
Leviticus 13:30-31
13:30 the priest is to examine the infection, and if it appears to be deeper than the skin and the hair in it is reddish yellow and thin, then the priest is to pronounce the person unclean. It is scall, a disease of the head or the beard.
13:31 But if the priest examines the scall infection and it does not appear to be deeper than the skin, and there is no black hair in it, then the priest is to quarantine the person with the scall infection for seven days.
