Why didn’t Avraham bless Yitzchak?
Why was Yitzchak unaware of whom he was actually blessing?
Neither Yaakov nor Moshe required savory dishes before offering their respective blessings.Why did Yitzchak require a savory dish before blessing his son?
Yitzchak, who dined on Esavs game, loved him while Rivkah loved Yaakov.
— Bereishis 25:28
And it was as Yitzchak aged and his eyes grew too weak to see that he summoned his older son Esav and said “My son” and he [Esav] responded “I am here.” … “go out in the field and trap me some game and make me a flavorful dish the way I love it and bring it to me to eat, so that my soul will bless you before I die.”
— Bereishis 27:1,3-4
And Elokim said “the earth should issue forth flora; seedbearing grasses and trees that are fruits that produce seed infused fruits along species lines upon the earth.” and it (almost) happened. The earth issued forth flora, plants bearing their seedbearing own species and trees [that are wooden] producing seed infused fruits …
— Bereishis 1:11-12
and trees that are fruits [The Divine Creative Will was] that the taste of the tree should be identical to the taste of the fruit. However, it [the earth was insubordinate and] did not do so but “the earth issued … trees [that are wooden] producing seed infused fruits,” but the trees themselves were not fruit. Therefore, when man was cursed because of his Original Sin, it [the earth] too was punished for its sin (and was cursed.)
— Rashi Ibid from Bereishis Rabbah 5:9
HaShem Elokim said to Adam “Because you hearkened to your wife’s voice and ate of the Tree regarding which I specifically commanded you ‘Do not eat from it’ the earth will be cursed on account of you. All the days of your life you will eat of it [the earth’s produce] with sorrow. It will sprout thorns and thistles for you … “
— Bereishis 3:17,18
HaShem Elokim commanded the man saying: “Eat from all the trees of the garden. And from the Tree of Knowledge /Union of Good and Evil do not eat from it. For on the day that you it from it you will definitely die.”
— Bereishis 2:16,17
The woman saw that the Tree was good to eat, desirable to the eyes and attractive as a means to gain intelligence. She took from its fruits and ate and also gave some to her husband with her — and he ate.
— Bereishis 3:6
… but you shall not sever it; for man is a tree of the field
— Devarim 20:19
The Biskovitzer poses several pointed questions about the brachos-blessings; that Yitzchak bestowed on Yaakov, while under the impression that he was Esav:
Why, in fact, did Yitzchak deliver his brachos erroneously and unconsciously? Why was Yaakov’s worthiness for benediction concealed from Yitzchak, the conduit of blessing? Even with his physical vision impairment and the willful blindness caused by his love for his eldest son, as a prophet, Yitzchak could easily have been informed by HaShem that Yaakov is the son deserving of blessing.
We find two other great figures in TeNaK”h who bestowed brachos; Yaakov — first on his grandchildren Ephraim and Menashe — and then later, on his deathbed, on his sons. Immediately preceding his death Moshe blessed the Tribes of Israel as well. Yet neither Yaakov nor Moshe requested mataamim-a flavorful dish; in order to elicit their brachos; so why did Yitzchok?
In order to appreciate the Biskovitzer’s approach to resolving these questions we must first examine how some of the great Torah thinkers understood the roots of blessing and curse.
The Original Sin of the first human beings was not merely the first in a long unbroken chain of transgression on the part of humanity; it was qualitatively different from almost all subsequent sins. The magihah-writer of the annotations; in Nefesh haChaim explains that while the original humans were endowed with bechirah chofshis-free will; there was still a paradigm-shifting difference between their bechirah chofshis and ours.
