Q. Why would Isaac bless (predict) Esau to break away from Jacob? Isn’t that cursing Jacob with trouble in the future? Maybe that accounted for all the problems in Middle East today? Why was Jacob rewarded for deceiving Isaac and stealing Esau’s blessing?
A. Isaac blessed Esau because he loved him, even though God already told Rebekah “the older shall serve the younger” (Gen 25:23):
• Gen 25:28 Now Isaac loved Esau, because he had a taste for game, but Rebekah loved Jacob.
Despite Isaac’s favoritism, all he could do was to state the negative of Jacob’s blessings for Esau:
Esau: Gen 27:39a Behold, away from the fertility of the earth shall be your dwelling,
Isaac: Gen 27:28b And of the fatness of the earth,
Esau: Gen 27:39b And away from the dew of heaven from above.
Isaac: Gen 27:28a Now may God give you of the dew of heaven,
Esau： Gen 27:40a By your sword you shall live, And your brother you shall serve;
Isaac: Gen 27:29a Be master of your brothers,
Esau: Gen 27:40b But it shall come about when you become restless, That you will break his yoke from your neck.
Isaac: Gen 27:29b And may your mother’s sons bow down to you.
The best that Isaac could bless Esau with was that he will break Jacob’s yoke from his neck. I do not consider that as cursing Jacob with trouble in the future, as Isaac himself blessed Jacob with “Cursed be those who curse you,” (Gen 27:29). He knew better than to curse Jacob.
I also don’t think Isaac’s prediction or prophecy caused the problems in the Middle East today. The children, representing two nations and two peoples (Gen 27:23), struggled within Rebekah (Gen 27:22) even before they were born:
• Rom 9:11-12 for though the twins were not yet born and had not done anything good or bad, so that God’s purpose according to His choice would stand, not because of works but because of Him who calls, it was said to her, “THE OLDER WILL SERVE THE YOUNGER.”
Jacob was not rewarded for deceiving Isaac and stealing Esau’s blessing. He was blessed because of God’s choice, before they were born and had done anything good or bad. God did not explain His choice, just as He did not explain why He allowed Esau (Edom) to break Jacob’s (Israel’s) yoke from his neck. The election was purely His sovereign choice, and He allowed Rebekah’s and Jacob’s deception to offset Isaac’s prejudice to accomplish His purpose. The Bible did not say anything beyond that, and I can go only as far as the Bible revealed.
