Alright, so in Leviticus 13, we've got God telling Moses what to do if someone gets leprosy.

Basically, if someone has white spots or blotches on their skin, they gotta go to the priest. If the priest decides it's leprosy, the affected person has to go live outside the camp for a while.

Also, if the priest isn't sure about something, then the person with the leprosy has to hang out outside the camp for seven days. So, uh, if you've got a spotty complexion, I guess don't plan any trips for the foreseeable future.
