פרשת תולדות תשכ"ד - ברכת יצחק ליעקב

So God give thee of the dew of heaven, And of the fat places of the earth, And plenty of corn and wine.

And Isaac trembled very exceedingly, and said: ‘Who then is he that hath taken venison, and brought it me, and I have eaten of all before thou camest, and have blessed him? yea, and he shall be blessed.’

And Itzhak feared a great fear etc. - Rabbi Hama bar Hanina: very, more than the fear he feared on the altar. Said: Who is this done broker between me and the place, so that Yaacov will take the blessings, to Rivka they said. Rabbi Yochanan said: When one has two sons, one went out and one came in, will he fear?! But, when Esav entered to his father, hell entered with him. Rabbi Acha said: The walls of the house started to shake/boil. this what he said: "Who, where", who is it that will be baked here, me, or my son, Yaakov? Said God: Not you, nor your son, but is the one hunting game. Hunting game: Said Rabbi Elazar Bar Shimon: Hunter, how were you hunted, door-builder, how is your own door broken ?! This is what it said (Proverbs 12): "The slothful man shall not hunt his prey" The rabbis said: G-d will not be late and will not prolong for the liar and his pray. Rabbi Eliezer the son of R. Jose says: What is not scorch? Will not extend God a liar and a side ?! As R. Yehoshua ben Levi whole day was made a party to deer and languages, and an angel came and permissiveness, and poultry and troublemaker, and an angel came and Mfrihn. And why? (Proverbs L): human capital expensive and laborious, to Sheba Jacob it happen in heaven, and will take the world's main blessings diligent him. Rabbi Hanina ben Pappa Ask the Rabbi Acha, said to him: What is written, utterly precious human capital? He said, the hand of the righteous is a hard-working, not taking from Vikram's time to come in this world. And food from Rabbi Judah and Rabbi Nehemiah, Rabbi Yehuda says: all that was created during the six days of creation. Rabbi Nehemiah says: all good, he revised in the future. Said: Essentially what Hacillach? Said: I do not know, but I was tasting bread taste, flavor meat, fish flavor, taste grasshoppers, taste all the delicacies in the world. Rabbi knees: because flesh mentioned, immediately cried. Said: I am one bowl of lentil fed them dainty and took his birthright, you Shacillach meat more so! Rabbi Levi said: According to our father was Isaac not be afraid to say: I did not say well, I did not broken the reactor ?! Because he said his birthright taken, said my good health:

ויחרד [AND ISAAC] TREMBLED — Explain it as the Targum renders it ותוה, which means he was perplexed. The Midrashic explanation (Midrash Tanchuma, Toldot 11) is that he saw Gehinnom opening beneath him (Esau).

And Isaac trembled very exceedingly, and said: ‘Who then is he that hath taken venison, and brought it me, and I have eaten of all before thou camest, and have blessed him? yea, and he shall be blessed.’

גם ברוך יהיה YEA, AND HE SHALL BE BLESSED — In order that you may not say “If Jacob had not deceived his father he would never have received the blessing”, he, therefore, confirmed it, blessing him now of his own free will (Genesis Rabbah 67:2).

He shall be blessed. This was not an additional blessing but a statement of fact — Yitzchok sensed that his deceiver was already blessed or that his own blessings had taken effect whether he wanted them to or not. Thus the reason for his trembling was that he realized that his beloved son Eisov had lost the blessings forever.
