the greek Evangelion mentions 3 "places":
-Hades aδης (Ades) the "undeworld" it's a neutral place( it is not "hell"), is the place where ALL the death go no matter if it is a good person or bad, Christ "descended" into Hades, Hades has a good side ("paradise" or the "bosom of Abraham" ) and a bad side (Tartarus) both sides are separated.
-Tartarus Τάρταρος a place of torment (but it's not "hell") , this place is not eternal, its an intermediary stage of torment until "the second death"
-Gahenna γέεννα (Geenna) THIS is Hell the permanent place of suffering, "the lake of fire", after "the second death" this is the place where the wicked and non-believers will be ad-eternum
the King James makes the error to call all this places just "Hell"
