Batman: Holy horrors, Robin! It looks like our old foe, Leviticus, is back to plague us with his rules and regulations!

Robin: That's right, Batman! Leviticus 13 says that the priests must examine anyone who has a suspicious-looking skin disease.

Joker: Ha ha ha! Do they know what they're looking for, Batman?

Batman: Of course! They must look for anything that looks like a boil, a rash, or a bright spot on the skin.

Catwoman: But what happens if they find something?

Robin: If they find something, they must declare the person to be "unclean" and the person must be kept apart from the rest of the community.

Riddler: And what if the disease goes away?

Batman: Then the person must be examined again by the priest. If the priest declares that the person is clean, then they can re-enter the community.

Penguin: Pah! So much for Leviticus' rules!

Batman: We must remain vigilant, Robin! We must be prepared for any plot Leviticus might have up his sleeve!
