We hear about two Messiahs who fell into the gulf together with the Shechinah. Rav Hamnuna Saba tells Moses that he is the one who will repair the pit. He talks about four exiles and four Klipot, the fourth of which is called a pit. We hear that the fourth exile is a generation of evil people, and that it is empty without the Torah; this is how it will be at the end of the exile. We hear that death is poverty of knowledge, and that for Moses' sake all the Tannaim and Amoraim above will descend into the deep to help him.
