Midras Mazmur 49:15: Ein Yaakov (Glick Edition), Seder Olam Rabbah, Bereshit Rabbah & Pesikta Rabbati

We are taught in a Baraitha: The school of Shammai says: "Three classes of people appear on the day of Judgment: the perfectly righteous, the grossly wicked, and the intermediate class. The sentence of eternal life is promptly written and sealed for the perfectly righteous; the sentence of Gehenna is promptly written and sealed for the grossly wicked; as it is said (Dan. 12, 2) And many of them that sleep in the dust shall awake, some to everlasting life, and some to shame and everlasting contempt. The intermediate class descend to Gehenna (Fol. 17), but they weep and come up again, as it is said (Zech. 13, 9) And I will bring the third part through the fire, and I will refine them as silver is refined, and will try them as gold is tried; and he shall call on My name, and I will answer him. Concerning this last class of men Hannah said (I Sam. 2, 6) The Lord causeth to die and maketh alive. He bringeth down to the grave and bringeth up again." But the school of Hillel says: "And He who abounds in kindness inclines [the scale of justice] towards the side of kindness. Concerning this third class of men David said (Ps. 116, 1) It is lovely to me that the Lord heareth my voice; in fact, David applies to them the entire chapter, including Thou hast delivered my soul from death (Ib. 8)." Jews who sin with their bodies as well as non-Jews who sin with their bodies, descend to Gehenna, and their punishment is to be in Gehenna for a period of twelve months; after that time their bodies are destroyed and their souls burnt, and the winds scatter and turn their ashes under the soles of the feet of the righteous, as we read (Mal. 3223) And ye shall tread down the wicked, for they shall be as ashes under the soles of your feet; but as for heretics, informers, Epicureans (disbelievers) who deny the Torah or resurrection, or who separate themselves from the congregation, or those (rulers) who tyrannize the land of the living, or who sin and cause others to sin, as did Jeroboam, the son of Nebat, and his associates, — they all descend to Gehenna, and are judged there from generation to generation; as it is said (Is. 66, 24) And they shall go forth and look upon the carcasses of the men who have transgressed against Me; for their worm shall not die, neither shall their fire be quenched. Even when Gehenna will be destroyed, they will not be consumed, as it is said (Ps. 49, 15) And their forms wasteth away in the nether world. But, why to that extent? Because they laid their hands on the Temple; as it is said: "From their own dwelling. Mi-zbul; and the word z'bul refers to the Temple, as it is said (I Kings 8, 3) I have indeed built a dwelling place (z'bitl) for Thee. It is said above: Concerning them said Hannah, The Lord causeth to die and maketh alive." R. Isaac b. Abin said: "Their faces are black like the sides of a caldron;" while Raba remarked: "Those who are now the handsomest of the people of Mechuzza will yet be called the children of Gehenna."

... The judgment of the wicked in Gehinnom lasts twelve months, as it says “And it shall be from new moon to new moon…” (Yeshayahu 66:23) R’ Yochanan ben Nuri says: from Pesach until Atzeret (Shavuot), as it says “…and from Sabbath to Sabbath…” (ibid.) After twelve months the souls of the sinners of Israel who transgressed the Torah and the commandments are consumed and their bodies are consumed and they are turned to dust. Gehinnom spits them out and the wind scatters them underneath the feet of the righteous, as it says “And you shall crush the wicked, for they will be as ash under the soles of your feet…” (Malachi 3:21) But those who separated from the ways of the community, like the Sadducees, and the betrayers and the hypocrites and the heretics, and those who ‘spread their terror in the land of the living,’ and those who denied the resurrection, and those who say Torah is not from heaven, and those who scoff at the words of the Sages – Gehinnom is locked before them and they are judged there forever, as it says “And they shall go out and see the corpses of the people who rebelled against Me…” (Yeshayahu 66:24) Not only this, but the netherworld will cease to be but they will not cease to be, as it says “…and their form will outlast the grave as his dwelling place (zevul).” (Tehillim 49:15) From His dwelling place He will wear out their form, and their form will wear out the netherworld. What caused this to happen to them? Because they stretched out their hands against the dwelling place, as it says ‘as his dwelling place,’ and there is no dwelling place other than the Holy Temple, as it says “I have surely built You a house to dwell in…” (Melachim I 8:13)

“Noah begot three sons, Shem, Ḥam, and Yefet” (Genesis 6:10).It is written: “Planted in the House of the Lord, they blossom in the courts of our God” (Psalms 92:14). “Planted in the House of the Lord,” this is Noah, whom the Holy One blessed be He implanted in the ark; “they blossom in the courts of our God,” – “Noah begot…Shem, Ḥam, and Yefet.” “They will continue to yield fruit even in old age; they will remain full and fresh” (Psalms 92:15). “They will continue to yield fruit [even in old age],” this is Noah;³Who begot children at age five hundred. “they will remain full and fresh” – “Noah begot.”
Rabbi Yudan said: What is the reason that all the generations begot children at one hundred years or at two hundred years, but this one [Noah] begot at five hundred years? However, the Holy One blessed be He said: ‘If they will be wicked, I do not want them to be eradicated by the water;⁴He did not want to upset Noah. if they will be righteous, I would be imposing upon him [Noah] to make several arks for them. So the Holy One blessed be He suppressed his [Noah’s] fount,⁵His ability to procreate. and he begot only at five hundred years. Rabbi Neḥemya said in the name of Rabbi Eliezer son of Rabbi Yosei HaGelili: [It was so that] even Yefet, who was the eldest, would not yet be one hundred years old – when he became subject to punishment⁶In those days, as explained above. – when the Flood came.
Rabbi Ḥanina said: In the future there will be no death except for idolaters. Rabbi Yehoshua ben Levi said: Neither for Israel, nor for idolaters, as it is stated: “[He will destroy death forever, and] the Lord God will wipe tears from all faces” (Isaiah 25:8). What does Rabbi Ḥanina do with “from all faces”? It is from the faces of Israel. But is it not written: “As the youth will die when he is one hundred years old”? (Isaiah 65:20). This supports Rabbi Ḥanina. What does Rabbi Yehoshua ben Levi do with it? [It means that at that age] he will be fit for punishment.
But is it not written: “Like sheep, they are destined for the grave; death will shepherd them. The upright will rule over them”? (Psalms 49:15). This supports Rabbi Ḥanina. What does Rabbi Yehoshua ben Levi do with it? Because in this world, there was Pharaoh at his time, Sisera at his time, Sennacherib at his time,⁷They were all punished. but in the future, the Holy One blessed be He will appoint the angel of death as the permanent sentry.⁸To administer eternal punishment. They will not rise up from the dead in the future, but those who are alive at that time will not die. That is what is written: “The upright will rule over them in the morning; their form will be consumed in the grave,⁹Literally, their form will wear out the grave. an abode [zevul] for him” (Psalms 49:15) – this teaches that the grave may wear away, but their bodies will not wear away.¹⁰But will be subject to eternal torment. Why to that extent? [“An abode for him”] – because they extended their hands against the Temple, as it is written: “I have built You an abode [zevul]” (I Kings 8:13).
