יִרְאַ֤ת יְהוָ֨ה ׀ טְהוֹרָה֮ עוֹמֶ֪דֶת לָ֫עַ֥ד מִֽשְׁפְּטֵי־יְהוָ֥ה אֱמֶ֑ת צָֽדְק֥וּ יַחְדָּֽו׃
Bojaźń Boża czysta, ostoi się na wieki; ustawy Boże prawdą, sprawiedliwe społem.

In this way he consummates the hypothesis he had put forward regarding the reason for the suffering of the righteous, namely, that it is a contingent of an exchange. Job had parried and rebutted this notion strenuously. However, his arguments are only pertinent if the exchange takes place in this world; that it is here that God rewards the person with good in compensation for the bad he has suffered, and not in the Hereafter. But if He compensates the person with an everlasting spiritual reward that is bestowed on his eternal soul, granting him eternal bliss in recompense for the temporary suffering, Job's submissions fail, and the Lord's justice is vindicated along with Him (Psalms 19:10). Thus, all of Job's responses are rebutted; all gone up in smoke (Psalms 37:20).

Judgments of truth. . . In other words, Torah judgment, as it is written [about the Torah], “The judgments of Hashem are true. . .” (Tehillim 19:10).
Tze'enah Ure'enah
Toldot Yizhak also writes about the four worlds. The verse first spoke about the world we are in now. It gives a righteous person anguish, poverty, and other troubles. It gives the evildoer wealth and happiness. Concerning this, the verse says, “His deeds are perfect” [32:4]. That is to say, the Holy One is whole with his deeds, what he does with the people on this world. In the next world, when he has died, some people are led into the Garden of Eden, and some other people are led into Gehenna. Why so, “all His ways are just” [32:4]. That is to say, in the next world we can see that God only does justice. He leads the evildoer who was rich in this world into Gehenna, because of his sins that he did in this world. The righteous person who had troubles and enough Gehenna in this world, he comes immediately into the Garden of Eden. However, the evildoer had enough Garden of Eden in this world, for the few commandments that he fulfilled. Therefore, he comes to Gehenna immediately in the next world. The Holy One pays the righteous person for his few sins in this world, expecting that he should have the next world immediately. It is not possible that a person should not commit sins, as the verse says, “for there is not one good man on earth who did what is best and does not sin” [Ecclesiastes, 7:21]. That is to say, the righteous person does much good, yet he has also committed sins. Concerning this, the verse says, “the judgments of the Lord are true, righteous altogether” [Psalms, 19:10]. That is to say, when people see that things go poorly for the righteous in this world and it goes well for the evildoer, they wonder why things should go badly for the righteous. Therefore, the verse says that the judgments of the Holy One are all just. When he would join the two worlds, then he would see that the Holy One is just. Thus, the righteous person had troubles in this world, but he has everything good in the next world. He does good for the evildoer in this world, but the Holy One causes troubles for him in the next world for his sins. Regarding the world of the Messiah it says here, “a faithful God” [32:4]. God is truthful. He will bring the Messiah to the dead, so that they should all arise. Some will not arise. This is the third world. Concerning this, he says, “never false” [32:4]. That is to say, He does no injustice when He brings some to life and not others. After this life that many people will come back to life, the Holy One will judge them for their sins. Some will remain alive with body and soul. This is called the world to come. This is the fourth world. Some will die and their body and soul will be lost forever. Concerning this, he said, “true and upright is He” [32:4]. That is to say, He is righteous because He lets them live. “Just,” He is just in that He destroys the evildoers forever.10Toldot Yizhak, Deuteronomy, 32:4–5.
