Second Tractate Bava Metzi'a(The Middle Gate)
Chapter 4 - All descend to Hell? [Surely not! What he meant was,] All descend to Hell and then return except for three, who descend but do not ascend, and these are they: one who sleeps with another man's wife, one who puts another to shame in public and one who uses an offensive nickname for someone.
(Footnote - Rabbi Hanina seems to understand Hell as a place of purgation.(emphasis mine))

Twelfth Tractate Hagiga (The Festival Sacrifice)
Chapter 2 - When The Other died [the angelic 'judges' in the world beyond the grave] said, He cannot be sentenced [to punishment], nor can he be admitted to the World to Come. He cannot be sentenced [to punishment] since he has engaged in [the study of] Torah; he cannot be admitted to the World to Come since he has sinned.
Rabbi Meir said, Better they should sentence him [to punishment], so that [when his sin is purged] he can be admitted to the World to Come. When I die I shall make [sure that] smoke arises from his grave.
(Footnote - Elisha will be punished for his sin by being burnt, and when his sin is purged he will be able to enter the World to Come.) (emphasis mine)
