Midrash su I Re 1:1

“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.

Similarly, concerning King David it is written: Now King David was old (I Kings 1:1). When he drew near to death, it is written about him: Now the days of David drew near that he should die (ibid. 2:1).

And also in the case of David, it is written of him (in I Kings 1:1): NOW KING DAVID WAS OLD. Then, when he was about to die, what is written (in I Kings 2:1)? THEN, WHEN THE DAYS FOR DAVID TO DIE DREW NEAR. "King David" is not written here but THEN, WHEN THE DAYS FOR DAVID < TO DIE > DREW NEAR.⁸I.e., David lost the royal title shortly before his death. Deut. R. 9:3. And also in the case of Jacob, when he was at the point of death, he began humiliating himself with Joseph and said (in Gen. 47:29): PLEASE, IF I HAVE FOUND FAVOR IN YOUR EYES. When? When he was approaching death (according to the beginning of the verse): THEN, WHEN THE DAYS FOR ISRAEL TO DIE DREW NEAR.

[(Gen. 24:1:) NOW ABRAHAM WAS OLD.] Come and see: From Adam even to Abraham there are twenty generation, but there is no < mention of > old age written about < any of > them except about him.¹⁷BM 87a; Sanh. 107b; Gen. R. 59:6; 65:9; below, 6:7; PRE 52. They sired children and grandchildren, but one did not recognize which was the son and which was the father. Also the children were striking the fathers without knowing it, as stated (in Ps. 78:33): SO HE ENDED THEIR DAYS IN FUTILITY AND THEIR YEARS IN TERROR, because they were all alike until Abraham came along. Then the Holy One gave him this < gray > crown which is an ornament for when one becomes old. And when did it come over him? When he practiced righteousness, since it is stated (in Prov. 16:31): GRAY HAIR IS A CROWN OF GLORY. And how do you find it? (Ibid., cont.:) IT IS FOUND BY WAY OF RIGHTEOUSNESS. To whom does this < verse > refer? To Abraham, concerning whom it is written (in Gen. 18:19): FOR I HAVE CHOSEN HIM SO THAT HE MAY CHARGE < HIS CHILDREN AND HIS HOUSEHOLD AFTER HIM TO KEEP THE WAY OF THE LORD, TO PRACTICE RIGHTEOUSNESS AND JUSTICE >…. The Holy One said to him: By your life, you are worthy of an old age. It is therefore stated (in Gen. 24:1): NOW ABRAHAM WAS OLD. Now David also received this crown, as stated (in I Kings 1:1): NOW KING DAVID WAS OLD. Why? Because he had acted according to Abraham's standard, as stated (in II Sam. 8:15): AND DAVID PRACTICED JUSTICE AND RIGHTEOUSNESS TOWARD ALL HIS PEOPLE. It is therefore stated (in Prov. 16:31): GRAY HAIR IS A CROWN OF GLORY.

Moshe immediately arose and went to Yehoshua's home. Yehoshua was frightened and said, "Moshe, my rabbi, come next to me." They left to go, and Moshe walked on Yehoshua's left. They entered the Tent of Meeting, and the pillar of cloud descended and stood in between them.

96:3 "And Israel approached the time of dying" (Gen 47:29). It is written, "No one rules over the wind to restrain the wind, and there is no ruling over the day of death" (Eccles 8:8). Rabbi Yehoshua of Sichnin said in the name of Rabbi Levi: The trumpets which Moses made in the wilderness were hidden by the Holy One, who is blessed, when Moses neared death so that no one else would sound them while they were coming to him, as it is written, "Gather to me all the elders of your tribes" (Deut 31:28), in order to fulfill what is stated, "And there is no ruling over the day of death"....And so too when Jacob neared death he began to lower himself before Joseph and said to him, "Please, if I have found favor in your eyes" (Gen 47:29). When [did he say this]? As he was approaching death, as it is stated, "And Israel drew near to the time of dying" (ibid.).
