Dover Echad l'Dor (Moshe and Moshiach)

Sanhedrin 8a

Rabbi Yochanan said that Moshe said to Yehoshua "you and the elders of the generation with them". The Holy One, blessed be He, said to him "take a stick and hit the elders over the head, for there is "dover echad l'dor" [Rashi: one leader] for a generation and not two leaders to a generation."

Sicha Parshas Bechukosai 5746

Every Jew has the power to receive from the "dover echad l'dor" his parnasa and all of his needs regarding children, health, and sufficient income in a way of "bread from heaven" (manna), both in those things which are necessary for existence as well as pleasureable things.

[...] and the fact that today it isn't possible to see the "jar of manna" which is "preserved for the generations" means that we must further speed up the time when the command to "preserve it for the generations" will be fulfilled in a revealed way -- with the coming of Moshiach tzidkeinu, who will come and redeem us and bring us upright to our land, in a way of "I will cause you to go upright" in the way of "the children of Israel went out with a high hand", "like the days of your coming out of Egypt I will show you wonders", all through Moshe Rabbeinu -- "the first redeemer is the last redeemer" since Moshe is the "dover echad l'dor" who provides Yidden with all of their needs [...] so too regarding the "final redeemer" of this final golus.
