ייִדישער מחשבֿה אויף שמואל א 9:8

And the nature of this "blessing" itself demands explanation. For there are only two possibilities here. The first is that Isaac's blessing took the form of plain prophecy, the revelation of what would transpire with these children in the future (not that Isaac's soul was inclined to one of the sons, whose good he desired and for whom he prayed). According to the first possibility the purpose of the savory foods (which Isaac asked Esau to prepare) was not that the soul of Isaac unify itself in love of the son who prepared these foods with the intent of praying for his prosperity, but that his soul be readied for the communion which would enable it to reveal his future. This has its parallel in the answer given to Saul by his servant, viz. (I Samuel 9:8): "I have in my hand the fourth part of a shekel of silver. I will give that to the man of G-d and he will tell us our way," and, as Yerovam said to his wife (I Kings 14:3): "And take with you ten loaves, and cracknels, and a bottle of honey, and go to him. He will tell you what will become of the child."
