Cita sobre Génesis 23:1

In Rashi - The years of the life of Sarah: All of them were equally good: It can be said that it is the way of a simple person that by way of growing older and increasing his knowledge, his ways become settled. So it comes out that the more he ages, the more he discards bad traits and actions that he would do [in the past]. And if so, only his last moment is called the days of his life, such that he has attained a proper completeness, if he merits it. But with the righteous Sarah, all of her days were proper and without corruption. Even if she certainly elevated herself in her old age, it was not by way of pushing off the earlier actions from the days of her youth. Rather she elevated herself, according to how she was created. For all of a person's days are measured to fix something particular every day, and to raise oneself from one level to another. But she had no flaw or corruption to reform and act more properly. And that is [the meaning of] that which he wrote, "All of them were equally good." And understand [this].

"And the life of Sarah was... years... these were the years of the life of Sarah" (Bereishit 23:1). Rashi explains that the repetition of "years" in each clause indicates that at twenty she was without sin, as she was at one hundred. This phrase, "the years of the life of Sarah," highlights that all her years were equally good. We must understand what this teaches us, for it seems that no other righteous woman in the Torah is described with such greatness. Furthermore, it is puzzling that even though the Torah later uses similar wording regarding Avraham Avinu and Rashi also comments that he was without sin, it does not repeat the phrase "the years of Avraham" to emphasize that all his years were equally good.
