Midrash su Isaia 34:4

“Vanity of vanities, said Kohelet; vanity of vanities, everything is vanity” (Ecclesiastes 1:2).
“Vanity of vanities [havel havalim]” – Rabbi Huna said in the name of Rabbi Aḥa: David made a statement and did not explain it, but his son Solomon explained it. Solomon made a statement and did not explain it, but his father David explained it. David said: “Man is like hevel” (Psalms 144:4); to what hevel [is man compared]? If it is to the hevel [heat] of an oven, it has significance. If it is to the hevel of a stove, it has significance. His son Solomon came and explained: “Vanity of vanities [havel havalim], said Kohelet.” Rabbi Shmuel bar Naḥmani taught it in the name of Rabbi Yehoshua ben Korḥa: It is comparable to a person who places seven pots on the fire one atop the other, and the heat of the upper one is insignificant.⁹This comparison is based on the fact that the term vanity [hevel] appears five times in Ecclesiastes 1:2, and twice it appears in the plural, for a total of seven mentions of the term hevel.
Solomon said: “For who knows what is good for man in his life, [all the days of his vain life,] that he spends like a shadow” (Ecclesiastes 6:12). What shadow? If it is like the shadow of a wall, it has substance. If it is like the shadow of a palm tree, it has substance. David came and explained: “His days are like a passing shadow” (Psalms 144:4). Rabbi Huna [said] in the name of Rav Aḥa: Like that bird that passes and its shadow passes with it. Shmuel said: Like the shadow of bees that have no substance at all.
Rabbi Shmuel bar Rav Yitzḥak taught it in the name of Rabbi Shimon ben Elazar: The seven vanities [havalim] that Kohelet mentioned correspond to the seven worlds that a person sees. A one-year-old is like a king who is on a canopied litter and everyone is hugging and kissing him. A two- or three-year-old is like a pig that extends its hands into the sewers. A ten-year-old jumps like a goat. A twenty-year-old whinnies like a horse, beautifies himself and seeks a wife. When he marries a wife he is like a donkey. When he begets children, he is as audacious as a dog to bring [home] bread and food. When he grows old, he is like a monkey. That is stated regarding the common people; however, regarding Torah personalities, it is written: “King David was old” – even though he was old, he was a king.
Rabbi Yehuda ben Rabbi Simon said: The seven vanities that Kohelet mentioned correspond to the seven days of Creation. On the first, “In the beginning God created the heavens and the earth” (Genesis 1:1), and it is written: “For the heavens will vanish like smoke” (Isaiah 51:6). On the second: “Let there be a firmament” (Genesis 1:6), and it is written: “The heavens will be furled like a scroll” (Isaiah 34:4). On the third: “Let the waters be gathered” (Genesis 1:9), and it is written: “The Lord will destroy the tongue of the sea of Egypt” (Isaiah 11:15). On the fourth: “Let there be lights” (Genesis 1:14), and it is written: “The moon will be disgraced” (Isaiah 24:23). On the fifth: “Let the waters swarm [with swarms of living creatures, and let fowl fly above the earth in the open firmament of heaven]” (Genesis 1:20), and it is written: “I will destroy the birds of the heavens” (Zephaniah 1:3). On the sixth: “Let us make man” (Genesis 1:26), and it is written: “I will destroy man and animal” (Zephaniah 1:3). Regarding Shabbat, what do you have to say? “One who profanes it will be put to death” (Exodus 31:14). That is stated regarding one who does so intentionally; but [one who profanes it] unwittingly, he will bring an offering and gain atonement. When Adam saw the praise of Shabbat, that one who brings an offering gains atonement, he began singing in its regard to the Holy One blessed be He, praise and psalm. That is what is written: “A psalm, a song for the day of Shabbat” (Psalms 92:1). Rabbi Levi said: This [psalm] was stated by Adam.

(Exodus 18:18) "You will languish": R. Yehoshua says: They will wear you out and cause you to collapse. R. Elazar Hamodai says: They will belabor you and vex you, as a fig tree whose leaves are wilted, viz. (Isaiah 1:30) "like an elah of wilted leaf." "also you": Moses; "also": Aaron; "also this people": the seventy elders. These are the words of R. Yehoshua. R. Elazar Hamodai says: "you" — Moses; "also" — Aaron, Nadav, and Avihu; "this people" — the seventy elders.

THE NEW HEAVENS AND EARTH
RABBAN GAMALIEL said: Just as the New Moons are renewed and sanctified in this world, so will Israel be sanctified and renewed in the future world just like the New Moons, as it is said, "Speak unto all the congregation of the children of Israel, and say unto them, Ye shall be holy: for I the Lord your God am holy" (Lev. 19:2). The sages say: The heavens and the earth are destined to pass away and to be renewed. What is written concerning them? "And all the host of the heaven shall be dissolved, and the heavens shall be rolled together as a scroll" (Isa. 34:4). Just as when a man reads in a scroll of the Torah and he rolls it, and again he opens it to read therein and he rolls it (together), likewise in the future will the Holy One, blessed be He, roll together the heavens like a scroll, as it is said, "And the heavens shall be rolled together as a scroll" (ibid.); "And the earth shall wax old like a garment" (Isa. 51:6); just as a man spreads out his garment and folds it up, and again he unfolds it || and puts it on and renews it (thereby), likewise the Holy One, blessed be He, in the future will fold up the earth and again will He spread it out and put it in its place like a garment, as it is said. "And the earth shall wax old like a garment" (ibid.).

Rabbi Eliezer said: All the host of heaven in the future will pass away and will be renewed. What is written concerning them? "And all the host of heaven shall be dissolved" (Isa. 34:4). Just as the leaves fade from off the vine and the fig tree, and the latter remain standing as a dry tree, and again they blossom afresh and bear buds and produce new leaves and fresh leaves. Likewise in the future will all the host of heaven fade away like a vine and a fig tree, and they will again be renewed before Him to make known that there is passing away (which) does not (really) pass away. No more shall there be evil, and no more shall there be plague, and (there shall) not be the former misfortunes, as it is said, "For, behold, I create new heavens" (Isa. 65:17).
