Gehenna, or Gehinnom (Hebrew: גהנום, גהנם) is the Jewish version of Hell that is portrayed within the Tanakh, Talmud and other Jewish sources and scripture. It is stated in the Seder Nezikin Sanhedrin in Jewish scripture, that "Gehenna is considered a Purgatory-like place where the wicked go to suffer until they have atoned for their sins." Furthermore, it is stated that the maximum amount of time a sinner can spend in Gehenna is one year.
Gehenna is different from the Christian or Islamic versions of Hell due to the fact that one does not suffer in Gehenna for all eternity.
