Musar zu Bereschit 24:1

ואברהם זקן בא בימים . The emphasis on the word בימים, which at first glance seems superfluous, teaches us that a person must be concerned every single day of his life to do good and not to sin. When he thinks in this vein only, every single day of his life will assume meaning. His reverence for G–d will result in his being granted more years. The years of the wicked, on the other hand, become shortened; this means that even if they live chronologically speaking for many years, the sum total of their life is short, seeing it was not filled with worthwhile activities. When Abraham is described as "aging," this means that he had made every one of his days count.

Nachmanides deals with the problem at length and is worth reading (cf. 24,1). I shall also make a contribution to these puzzling and conflicting statements. Nachmanides follows his method, whereas I shall follow mine.

The verse states, “And Avraham was old, advanced in days [years]” (Bereishis 24:1). This is interpreted in Midrash Rabbah (Parashas Chayyei Sarah 59:6) by Rabbi Abba: “There are people who are ‘old’ but not ‘with days’ and there are others who are ‘with days’ but not ‘old.’ But in Avraham’s case his old age corresponded with his days and his days with his old age.”

Our forefather Avraham, on the other hand, merited both old age as well as beneficial days. Thus the plain meaning of the Midrash is that Avraham enjoyed a desirable lot even in this world. In fact, the Sages tell us in Baba Basra (16b) that there were three people to whom the Holy One Blessed is He gave a taste of the World to Come while they were yet in this world. They were: Avraham, Yitzchak and Yaakov. As it is written, “With everything” (Bereishis 24:1), “From everything” (ibid. 27:33), “Everything” (ibid. 33:11). However, I have heard a deeper explanation of the Midrash in the name of my illustrious mentor, Rabbi Yudel, ztz”l, president of the court and dean of the yeshiva of the holy community of Kauli. It is based upon a passage in the Zohar (Parashas Vayechi 221b) commenting on the verse, “And the days approached for Yisrael to die” (Bereishis 47:29). The Zohar asks: “On how many days does a person die (i.e. why is “days” in the plural)? Does the soul not exit in a single moment?” Explains the Zohar: When a person passes from this world all his days come for a reckoning before the Holy One Blessed is He. Not one is omitted. If a person behaved righteously and feared Hashem continually, if he clung to Him lovingly every day and was whole in his commitment to Torah, fear of Heaven, mitzvos and good deeds, then all his days will be crowned and garbed with splendor and majesty.
