Hidden Historical secrets, white lies and hidden truths

Esau pleaded, "But do you have only one blessing? Oh my father, bless me, too!" Then Esau broke down and wept.
Finally, his father, Isaac, said to him, "You will live away from the richness of the earth, and away from the dew of the heaven above. You will live by your sword, and you will serve your brother. But when you decide to break free,
you will shake his yoke from your neck.“ From that time on, Esau hated Jacob because their father had given Jacob the blessing. And Esau began to scheme: "I will soon be mourning my father's death. Then I will kill my brother, Jacob.“
Gen 27:38-41
