PG-13
The MPAA (Mishnah Policing Association of America) has given Leviticus a PG-13 rating, which means that parts of it are Pretty Gross in ways that kids may find hilarious once they hit puberty. Leviticus includes scenes of pus-leaking penises, menstrual flow that doesn't stop, and weird laws and descriptions of sex that you're not supposed to be doing (but c'mon, no one would bother to try to stop it if people weren't doing it every chance they got).
