 2 Peter 2.4 says, For God spared not the angels that sinned, but cast them down to hell and delivered them into chains of darkness to be reserved unto judgment. God originally created hell as a place of punishment for the devil and his angels who rebelled against him in heaven. When Lucifer rose up against God and led a third part of the angels in a rebellion against their own maker, God cast them out of heaven, and one day God will cast them into a place of eternal punishment called hell.
