Why Doesn't Isaac Take Back the Stolen Blessing?
Jacob—the “deceiver”—steals the blessing Isaac intends for Esau, the firstborn, by pretending to be Esau in the presence of their blind father. When Esau finds out about the deception, his response is one of the most heart-rending in scripture:
30 After Isaac finished blessing him, and Jacob had scarcely left his father’s presence, his brother Esau came in from hunting. 31 He too prepared some tasty food and brought it to his father. Then he said to him, “My father, please sit up and eat some of my game, so that you may give me your blessing.”
32 His father Isaac asked him, “Who are you?”
“I am your son,” he answered, “your firstborn, Esau.”
33 Isaac trembled violently and said, “Who was it, then, that hunted game and brought it to me? I ate it just before you came and I blessed him—and indeed he will be blessed!”
34 When Esau heard his father’s words, he burst out with a loud and bitter cry and said to his father, “Bless me—me too, my father!”
35 But he said, “Your brother came deceitfully and took your blessing.”
36 Esau said, “Isn’t he rightly named Jacob? This is the second time he has taken advantage of me: He took my birthright, and now he’s taken my blessing!” Then he asked, “Haven’t you reserved any blessing for me?”
37 Isaac answered Esau, “I have made him lord over you and have made all his relatives his servants, and I have sustained him with grain and new wine. So what can I possibly do for you, my son?”
38 Esau said to his father, “Do you have only one blessing, my father? Bless me too, my father!” Then Esau wept aloud.
[Genesis 27:30-38]
Here’s what I’ve wondered: Why can’t Isaac just bless Esau and renounce the blessing he pronounced over Jacob?
I think the answer lies in that strange detail about Isaac’s response when he realizes he has been deceived:
“Isaac trembled violently”.
Why does Isaac tremble?
When she was pregnant with the twins, Rebekah received a word from the Lord that it would be the younger son who would have preeminence over the elder. Isaac has favored the elder son, Esau, even though Esau is clearly not fit to receive and pass on the Covenant. Here, however, Isaac is confronted with the fact that, in spite of his sinful passivity with regard to his elder son, the Lord’s purposes are still realized in the blessing of the younger son, Jacob. I think Isaac trembles because he is struck in that moment of realization that God has been at work in spite of Isaac’s sin.
The reason Isaac cannot just retract the blessing he gave Jacob and give it again to Esau is because Isaac realizes that God intended for Jacob to receive the blessing. Isaac now “sees” (despite his blindness) that he blessed the correct son, even though he was tricked into doing so.
The point: God’s purposes will be achieved. All things opposing God will be defeated.
How can you work with the purposes of God today?
