Midrash su Ecclesiaste 4:5

He said: “The crooked cannot be mended, and deficiency cannot be counted” (Ecclesiastes 1:15) – in this world, one who is crooked can be mended, and one who is mended can become crooked. But in the future, one who is crooked cannot be mended, and one who is mended cannot become crooked. “And deficiency cannot be counted” – there are wicked ones who associate with one another in the world; one of them repented before his death, and one did not repent. It turns out that this one stands in the company of the righteous, and that one stands in the company of the wicked. He [the one who did not repent] sees him [the other one] and says: ‘Woe is me, perhaps there is favoritism in this matter? [Both] I and that one have stolen, both I and that one have killed; yet that one is standing in the company of the righteous, and this one [referring to himself] is standing in the company of the wicked.’ They [the angels] respond and say to him: ‘Fool of the world, you were despicable, and you were cast aside after your death for three days; did they not drag you to the grave with ropes? “Beneath you maggots are spread and worms are your cover” (Isaiah 14:11). When your friend understood this, he repented from that path. You, too, had the opportunity to repent, but did not do so.’ He says to them: ‘Allow me to go and repent,’ and they respond to him and say: ‘Fool of the world, do you not know that this world is like Shabbat, and the world from which you came is like the day before Shabbat. If a person does not prepare on the day before Shabbat, what will he eat on Shabbat? Moreover, this world is like the sea, and the world from which you came is like dry land. If a person does not prepare on dry land, what will he eat at sea? Moreover, this world is like the wilderness, and the world from which you came is like civilization. If a person does not prepare in civilization, what will he eat in the wilderness?’ What does he do? He folds his hands and eats his flesh, as it is stated: “The fool folds his hands and eats his flesh” (Ecclesiastes 4:5). He says: ‘Allow me to see my friend in his glory [in heaven].’ They say to him: ‘Fool of the world, we are commanded from the mouth of the Almighty, that the wicked will not stand alongside the righteous, and not the righteous alongside the wicked, not the impure alongside the pure, and not the pure alongside the impure. About what are we commanded? It is about this gate, as it is stated: “This is the gate of the Lord; the righteous shall enter into it”’ (Psalms 118:20).

When Solomon erected the Temple he prayed: Lord of the Universe, if a man should pray unto You in this Temple for money, and You know that the money will be harmful to him, do not give it to him, but if You should foresee that the money will be beneficial to him, fulfill his plea, as it is said: And render unto every man according to all his ways, whose heart Thou knowest—for Thou, even Thou only, knowest the hearts of the children of men (II Chron. 6:30). Because the wicked in this world are wealthy and dwell in tranquility, the Holy One, blessed be He, will reward them only a little for the good deeds they perform in this world, as it is said: And repayeth them that hate Him to their face (Deut. 7:10). But it is also written: When the wicked spring up as the grass, when all the workers of iniquity do flourish; it is that they may be destroyed for ever (Ps. 92:8). However, in the future, the Holy One, blessed be He, will open his treasure house to his righteous servants in the Garden of Eden, while the wicked, who have eaten the fruits of interest here, will consume their own flesh with their teeth and will be confounded, as it is said: The fool foldeth his hands together and eateth his own flesh (Eccles. 4:5). They will then cry out: Would that we had been workmen and carried burdens on our shoulders, as it is said: Better is a handful of quietness, than both the hands full of labor and striving after the wind (ibid., 6).

“That which is warped cannot be straightened, and that which is lacking cannot be counted” (Ecclesiastes 1:15).
“That which is warped cannot be straightened.” In this world, one who is warped can be straightened, and one who is lacking can be counted. But in the future, one who is warped cannot be straightened, and one who is lacking cannot be counted. There are those among the wicked who were friends with each other in [this] world. If one of them repented during his lifetime, before his death, and one of them did not repent before his death, the one who did so in his lifetime is privileged to stand in the company of the righteous, and the other one stands in the company of the wicked. He sees his counterpart and says: ‘Is there, perhaps, favoritism in this world? Woe to that man.¹⁰⁷He is referring to himself. The same is true of the third-person reference (“he”) in the next sentence. He and that one, we were together in the world. We were as one, we stole as one, we robbed as one, and we did all the evil deeds in the world together. Why is that one in the company of the righteous and this man is in the company of the wicked?’ They say to him: ‘You great fool, you were repulsive after your death for two or three days. They did not place you into a coffin, and they dragged you to your grave with ropes. “The maggot is spread under you and worms cover you” (Isaiah 14:11). Your counterpart saw your repulsiveness and took an oath to abandon his wicked path, and he repented like a righteous man. His repentance enabled him to take life, honor, and a portion here with the righteous. Why [are you being punished] to this extent? It is because you had the opportunity to repent, and had you repented, all would have been well for you.’
He says to them: ‘Allow me, and I will go and repent.’ They respond to him and say: ‘Oh, you great fool, don’t you know that this world is comparable to Shabbat, and the world from which you came is comparable to the day before Shabbat? If a person does not prepare on the day before Shabbat, what will he eat on Shabbat? Don’t you know that the world from which you came is comparable to dry land and this world is comparable to the sea? If a person does not prepare on dry land, what will he eat at sea? Don’t you know that this world is comparable to a wilderness, and the world from which you came is comparable to a settlement? If a person does not prepare in the settlement, what will he eat in the wilderness?’ Immediately, he grits his teeth and eats his flesh, as it is stated: “The fool folds his hands, and eats his flesh” (Ecclesiastes 4:5). He says: ‘Allow me and I will see the glory of my counterpart.’ They say: ‘You great fool, we are commanded from the mouth of the Almighty that neither will the righteous stand among the wicked, nor the wicked among the righteous, not the pure alongside the impure, nor the impure alongside the pure. What are we commanded regarding this gate? “This is the gate of the Lord, the righteous will enter it” (Psalms 118:20).’ Immediately, he rends his garments and pulls out his hair, as it is stated: “The wicked will see and be angered” (Psalms 112:10).
