Midrash su Geremia 30:9

R. Giddel said in the name of Rab: "In the future Israel will enjoy the abundance which the Messianic period will bring." R. Joseph said to him: "Is this not self-evident? Who else should then enjoy it, Hilek and Bilek?" By this he intended to disprove the theory of R. Hillel, who said [later] "Israel has no Messiah to expect, for they have already enjoyed him [through the glory] in the days of Hezekiah." Rab said: "The world is created only for such [great] men as David." And Samuel said: "For such men as Moses [for the purpose of giving a Torah]." And R. Jochanan said: "For such men as the Messiah." But what is his (Messiah's) real name? At the college of R. Shila, it was said: "Shila is his real name, as it is said (Gen. 49, 10) "Until Shilah will come." At the college of R. Janai, it was said: "Yinon is his real name, as it is said (Psalms 72, 17) "In the presence of the sun, Yinon is his name." And at the college of R. Chanina, it was said: "Chanina is his name, as it is said (Jer. 16, 13) So that I will not grant you Chanina (favor)." According to others, Menachem b. Hezekiah is his name, as it is said (Lam. 1, 16). Far from Me is Menachem, (comforter) that should refresh my soul." R. Juda, in the name of Rab, said: "In the future the Holy one, praised be He! will create for them (Israel) another David, as it is said (Jer 30, 9) And David, their king, whom I will raise up unto them. It does not read, I raised [in the past], but I will raise." R. Papa said to Abaye: "Is it not written (Ezek. 37, 25) David, My servant, shall be prince unto them forever? This is as it is now [the custom], a Caesar and a prince."
