Moses lays down the rules for anyone with damaged testicles, pus leaking infected wounds, hunchbacks, deaf people, blind people, and any other people with any kind of "defect"... they're not allowed anywhere near anything being offered to God or anywhere God likes to hang out. Because they disgust God... even though he's the one who made them that way.
They also tell you when you need to set your daughter on fire, at what point God will make you eat your fucking children, and when to throw rocks at people until they die!
