Eliyahu’s revelation in rabbinical literature is a contrast to the two previous revelations of Eliyahu after his ascent to heaven.  Eliyahu is mentioned, in Talmudic and Midrashic literature as appearing to save individuals from various states of distress, to clear up misunderstandings and quarrels between people, and to fill the role of Israel's great advocate before their Father in Heaven. While Eliyahu remains strict, it is not the same strictness that characterizes him in the Tanakh, directed towards the Israelites.  His sternness is now expressed on their behalf, and it is always directed against the sages and leaders of Israel.
