“The Old English hel belongs to a family of Germanic words meaning “to cover” or “to conceal.” Hel is also the name, in Old Norse, of the Scandinavian queen of the underworld. Many English translations of the Bible use hell as an English equivalent of the Hebrew terms Sheʾōl (or Sheol) and Gehinnom, or Gehenna (Hebrew: gê-hinnōm). The term Hell is also used for the Greek Hades and Tartarus, which have markedly different connotations. As this confusion of terms suggests, the idea of hell has a complex history, reflecting changing attitudes toward death and judgment, sin and salvation, and crime and punishment.”
