Kabbalah su Genesi 27:33

And some times the name Adona"y is called by the nickname "All/kol", and the reason is that there is absolutely no lack in it, behold: all types of flow and emanation and all types of blessing and the maintaining, all enter through it. And it is called Ko"l because all is in it, and regarding every type of need that anything needs in the world there is no deity to request it from except this, and no other place from where to request, because all is included in this name and from this place every requester will express their will, each according to their need and will, as s/he calls God with integrity (See Psalms 145:18). And more, Yesod, which is the aspect just above this, is called Kol/All, for principles that will be explained later with the help of Hashem. And this aspect that is called Ko"l was given as a gift by Y"Y to Avraham, as I explained to you, that behold that is the basis of the blessing and the pool. And regarding this there is the hint in It saying: "And Y"Y blessed Avraham with All" (Genesis 24:1). And from Avraham to Yitzchak, in It saying: "and I ate from All before you came and I blessed him" (Genesis 27:33). And from Yitzchak to Ya'akov, in It saying: "since Elohim was gracious to me and since I have All" (Genesis 33:11) the explanation is that Ya'akov said to Esav: lest you think that I will have any lack due to giving to you? Know that all the keys of the upper blessing are all given into my hand, and behold it is included in All, and this is "because I have All", and therefore I do not lack anything in giving something to you.

At that time Michael came before Jacob with the Shechinah. Isaac knew that and saw that the Garden of Eden is with Jacob, so he blessed him. When Esau entered, Gehenom entered with him. Therefore, "And Isaac trembled very much" (Beresheet 27:33), because he had previously thought that Esau was not of that side. Therefore he said "Moreover, he shall be blessed."

Come and behold, When Esau entered, Gehenom came with him, and Isaac trembled with fear, as it is written, "And Isaac trembled very much" (Beresheet 27:33). Why is "very much" used to describe "trembled."? Isaac never felt such fear and terror during his life. Even when he was strapped upon the altar and saw the knife, he did not tremble as when Esau entered and brought Gehenom with him. Then he said, "Before you came, and have blessed him? Moreover, he shall be blessed." For I saw the Shechinah approving those blessings.
