Various Christian commentators state that Jewish literature represents Elijah as one who appears from heaven to help in times of need.
The only example given is contained in the Babylonian Talmud Tractate Baba Mezi'a 114:
Rabbah b. Abbuha met Elijah standing in a non-Jewish cemetery. Said he [Rabbah] to him [Elijah]: Art thou not a priest: why then dost thou stand in a cemetery? — He replied: Has the Master not studied the laws of purity? For it has been taught: R. Simeon b. Yohai said: The graves of Gentiles do not defile, for it is written, And ye my flock, the flock of my pastures, are men; only ye are designated 'men'. — He replied: I cannot even adequately study the four [orders]; can I then study six? And why? he inquired. — I am too hard-pressed, he answered. He then led him into Paradise and said to him: Remove thy robe and collect and take away some of these leaves. So he gathered them and carried them off. As he was coming out, he heard a remark, 'Who would so consume his [portion in] the world [to come] as Rabbah b. Abbuha has done?' Thereupon he scattered and threw them away. Yet even so, since he had carried them in his robe, it had absorbed their fragrance, and so he sold it for twelve thousand denarii, which he distributed among his sons-in-law.
Are there other stories in Jewish literature that would support the claim that Elijah was viewed as someone who comes to help in times of need?
