Kabbalah su Genesi 27:6

Rabbi Yosi said, come and behold, If, heaven forbid, Esau would have been blessed at that time, Jacob would not have ruled over the world. But it was decreed by the Holy One, blessed be He, and everything happened as it should. Come and behold, It is written, "but Rivkah loved Jacob" (Beresheet 25:28), as has been explained. Therefore, she sent for Jacob and said to him "Behold, I heard your father speak to Esau your brother" (Beresheet 27:6).
