The concept of Hell does not change throughout the different books of the Bible, but the language and imagery used to describe it may vary. The Old Testament uses the term Sheol to describe the realm of the dead, while the New Testament uses Hades and Gehenna to refer to a place of punishment for the wicked. The book of Revelation provides a more detailed description of Hell as the Lake of Fire, but the basic concept of eternal separation from God remains consistent throughout the Bible.
