The generation of the flood has no portion in the world to come, nor will they stand at the [last] judgment, as it says, “[And the Lord said,] my spirit will not always enter into judgment with man” (Genesis 6:3), [meaning] there will be neither judgment nor [my] spirit for them. The generation of the dispersion have no portion in the world to come, as it says, “So the Lord scattered them from there upon the face of all the earth” (Genesis 11:8): “So the lord scattered them”, refers to this world, “And from there the Lord scattered them” (Genesis 11:9), refers to the world to come. The men of Sodom have no portion in the world to come, as it says, “And the men of Sodom were wicked and great sinners before the Lord” (Genesis 13:1: “wicked” in this world, and “sinners” in the world to come; Yet will they stand at judgment. R. Nehemiah says: “Neither [the generation of the flood nor the men of Sodom] will stand at judgment, as it says, “Therefore the wicked shall not stand in judgment, nor sinners in the congregation of the righteous” (Psalms 1:5) “Therefore the wicked shall not stand in judgment”, refers to the generation of the flood; “nor sinners in the congregation of the righteous”, refers to the men of Sodom. They [the Sages] said to him: “They will not stand in the congregation of the righteous, but they will stand in the congregation of the wicked.” The spies have no portion in the world to come, as it says, “And those men that spread such calumnies about the land, died by the plague before the lord” (Numbers 14:37): “[they] died” in this world, “by the plague” in the world to come. The generation of the wilderness have no share in the world to come and will not stand at the [last] judgment, as it says, “In this wilderness they shall be consumed, and there they shall die” (Numbers 14:3, according to the words of Rabbi Akiba.

The congregation of Korah is not destined to ascend [from the earth], as it says, “And the earth closed upon them” in this world, “and they perished from among the congregation” (Numbers 16:33) in the world to come, according to the words of Rabbi Akiba. Rabbi Eliezer says: “Concerning them it is said, ‘The Lord kills and makes alive: He brings down to Sheol, and brings up” (I Samuel 2:6). The ten tribes will not return [to the Land of Israel], for it is said, “And He cast them into another land, as is this day” (Deuteronomy 29:2: just as the day goes and does not return, so they too went and will not return: according to the words of Rabbi Akiba. Rabbi Eliezer says: “‘As is this day’ just as the day darkens and then becomes light again, so the ten tribes even as it went dark for them, so will it in the future become light for them.
