B'resheet 27:33 Then Yitz'chak trembled violently, and said, "Who was he then that hunted game and brought it to me, so that I ate of all of it before you came, and blessed him? Yes, and he shall be blessed."
The truth comes out.
B'resheet 27:34-35 When Esav heard the words of his father, he cried out with an exceedingly great and bitter cry, and said to his father, "Bless me, even me also, O my father!" And he said, "Your brother came deceitfully, and has taken away your blessing."
Blessings, it seems, are not revocable.
B'resheet 27:36 Then he said, "Is he not rightly named Ya'akov, for he has supplanted me these two times? He took away my birthright, and behold, now he has taken away my blessing." And he said, "Have you not reserved a blessing for me?"
Even though Ya'akov asked for his birthright, Esav freely choose to give away his birthright. He did not find it important as a bowl of food at the time. He obviously still blamed his brother for his own problems from his actions. Do we miss a greater blessing that could come our way because of our desire for other things in this physical world? I hope not.
B'resheet 27:37-38 But Yitz'chak answered and said to Esav, "Behold, I have made him your master, and all his relatives I have given to him as servants; and with grain and new wine I have sustained him. Now as for you then, what can I do, my son?" And Esav said to his father, "Do you have only one blessing, my father? Bless me, even me also, O my father." So Esav lifted his voice and wept.
One day Israel too will cry like Esav because many have missed the greater blessing of Yeshua HaMashiach and the greater responsibility of telling others about Him. "As a nation", they shirked their responsibility just like Esav did and missed out.
Zech 12:10-14 "And I will pour out on the house of David and on the inhabitants of Jerusalem, the Spirit of mercy/grace and of supplication, so that they will look on Me whom they have pierced; and they will mourn for Him, as one mourns for an only son, and they will weep bitterly over Him, like the bitter weeping over a first-born. "In that day there will be great mourning in Jerusalem, like the mourning of Hadadrimmon in the plain of Megiddo. "And the land will mourn, every family by itself; the family of the house of David by itself, and their wives by themselves; the family of the house of Nathan by itself, and their wives by themselves; the family of the house of Levi by itself, and their wives by themselves; the family of the Shimeites by itself, and their wives by themselves; all the families that remain, every family by itself, and their wives by themselves. NAS
A spirit of repentance (teshuvah) - this is also corresponds to the letter "Hay". If we admit our wrongs and return to the way the L-rd wants us to go He is ready to forgive and still bless us for the L-rd is kind. (chessed)
B'resheet 27:39-40 Then Yitz'chak his father answered and said to him, "Behold, away from the fertility of the earth shall be your dwelling, And away from the dew of heaven from above. "And by your sword you shall live, And your brother you shall serve; But it shall come about when you become restless, That you shall break his yoke from your neck."
The spirit of G-d was speaking through Yitz'chak.
B'resheet 27:41 So Esav bore a grudge against Ya'akov because of the blessing with which his father had blessed him; and Esav said to himself, "The days of mourning for my father are near; then I will kill my brother Ya'akov."
Instead of accepting it as the will of HaShem, Esav put it in his heart because of the blessing to kill his own brother.
B'resheet 27:42-43 Now when the words of her elder son Esav were reported to Rivkah, she sent and called her younger son Ya'akov, and said to him, "Behold your brother Esav is consoling himself concerning you, by planning to kill you. Now therefore, my son, obey my voice, and arise, flee to Haran, to my brother Laban!
77 years old and still obeying his mother.
B'resheet 27:44-45 "And stay with him a few days, until your brother's anger against you subsides, and he forgets what you did to him. Then I shall send and get you from there. Why should I be bereaved of you both in one day? "
Here we see the gentleness of Rivkah. She was sad for Esav too even though it was part of her doing that caused his grieve. The Ruach HaKodesh still grieves for Israel.
B'resheet 27:46 And Rivkah said to Yitz'chak, "I am tired of living because of the daughters of Heth; if Ya'akov takes a wife from the daughters of Heth, like these, from the daughters of the land, what good will my life be to me?" NAS
A better question is what good are our lives without our Messiah, without the true Messiah, without Yeshua HaMashiach?
