Hell is a temporary place of suffering for sinners after death. When evil
is finally defeated (at Frashegird), the souls of sinners will be released
from hell, and will be purified by the ordeal of molten metal. They will
then join the congregation of God and the saints.
The eternal burning Gehenna exists in Jahve-worship.
