Answer:
The Bible itself has very few references to life after death. , the bowels of the earth, is portrayed as the place of the dead, but in most instances Sheol seems to be more a metaphor for oblivion than an actual place where the dead “live” and retain consciousness.
The notion of resurrection appears in two late biblical sources, Daniel 12 and Isaiah 25-26
Daniel 12:2 — “Many of those that sleep in the dust of the earth will awake, some to eternal life, others to reproaches, to everlasting abhorrence” — implies that resurrection will be followed by a day of judgment. Those judged favorably will live forever and those judged to be wicked will be punished.
Explanation:
Indeed, the notion of heaven and hell may be the most ambiguous of all Jewish afterlife ideas. References to Gehinnom as a fiery place of judgment can be found in the apocalyptic literature of the Second Temple period. The Talmud embellished this idea, claiming that Gehinnom is 60 times hotter than earthly fire (Berakhot 57b).
The earliest reference to Gan Eden (the Garden of Eden) and Gehinnom as a pair is probably the rabbinic statement of the - sage Yochanan ben Zakkai: “There are two paths before me, one leading to Gan Eden and the other to Gehinnom (Berakhot 28b).”
