What is the difference between the first circle of hell (linmbo) and the othercircle?

Limbo is where unchristian and pagans go in the after life while the second circle(which i'm assuming you're talking about)  is where sinners of Lust go.

Because they have eight wheels and four people on them, and four plus eight makes twelve, and there are twelve inches in a foot, and one foot is a ruler, and queen elizabeth was a ruler, and queen elizabeth was also a ship, and the ship sailed the seas, and there were fish in the seas, and fish have fins, and the finns fought the russians, and the russians are red, and fire trucks are always “russian" around, so that's why fire trucks are red, and this is wht\huhf.
