Midrasch zu Tehillim 1:5

MISHNA: The generation of the flood have no share in the world to come, and are also not judged, as it is said (Gen. 6, 3) Lo yadon ruchi b'adam forever, i.e., no judgment and no spirit. The generation of dispersion (Ib. 11) have also no share in the world to come, as it is said (Ib. 8) And the Lord scattered them abroad. The men of Sodom have also no share in the world to come, as it is said (Ib. ib. 13) For the men of Sodom were wicked, and sinners before the Lord exceedingly, i.e., wicked in this world, and sinners in the world to come. However, they have to appear before judgment. R. Nechemiah says: "Both of the above are not to appear before judgment, as it is said (Ps. 1, 5) Therefore shall the wicked not be able to stand (Fol. 108) in the judgment, and sinners in the congregation of the upright; i.e., therefore shall the wicked not be able to stand in the judgment, refers to the generation of the flood; and sinners in the congregation of the upright, refers to the men of Sodom." The sages, however, said to him: "The passage means that among the congregation of the upright, the latter cannot stand, but they can stand among the congregation of the wicked [hence they face judgment]."

The spies have no share in the world to come, as it is said (Num. 14, 37) Died by the plague before the Lord; i.e., died — in this world; plague — in the world to come. The generation of the desert has no share in the world to come, as it is said (Ib. ib. 35) In this wilderness shall they die, and therein shall they be spent; etc., i.e., in the wilderness shall they die, in this world; and therein shall they be spent, in the world to come. So says R. Akiba. R. Eliezer, however, maintains: "Concerning them, Scripture says: (Ps. 1, 5) Gather together unto Me My pious servants, who make a covenant with Me by sacrifice. The congregation of Korah will not be restored [at the time of resurrection], as it is said (Num. 16, 33) And the earth closed over them, i.e., in this world; and they disappeared from the midst of the congregation — in the world to come." So says R. Akiba. R. Eliezer, however, says: "Concerning them, Scripture says: (I Sam. 2, 6) The Lord killeth and maketh alive; he bringeth down to the grave, and he bringeth up."
