The people of the Generation of Dispersion - the Tower of Babel - have no share in the World to Come since God "dispersed them" in this world and "scattered" for the World to Come.
The people of Sodom have no share in the World to Come since they were "wicked" (this world) and "sinful" (World to Come).
The people of the Generation of the Wilderness have no share in the World to Come since they shall be "consumed" and "there they shall die" - these are the words of Rabbi Akiva. Rabbi Eliezer disagrees and applies them: "Gather to Me My devout ones, those who sealed a covenant with Me by sacrifice."
