27 The boys grew up, and Esau became a skillful hunter, a man of the open country, while Jacob was a quiet man, staying among the tents. 28 Isaac, who had a taste for wild game, loved Esau, but Rebekah loved Jacob.
29 Once when Jacob was cooking some stew, Esau came in from the open country, famished. 30 He said to Jacob, “Quick, let me have some of that red stew! I’m famished!” (That is why he was also called Edom.)
31 Jacob replied, “First sell me your birthright.”
32 “Look, I am about to die,” Esau said. “What good is the birthright to me?”
33 But Jacob said, “Swear to me first.” So he swore an oath to him, selling his birthright to Jacob.
34 Then Jacob gave Esau some bread and some lentil stew. He ate and drank, and then got up and left. So Esau despised his birthright.
So, Esau not only had his blessing stolen by Jacob (right before their father Isaac died, as Jacob impersonated Esau), but he sold his first-born rights to Jacob for almost nothing. They did not get along after that:
38 Esau said to his father, “Do you have only one blessing, my father? Bless me too, my father!” Then Esau wept aloud.
39 His father Isaac answered him,
"Your dwelling will be
away from the earth’s richness,
away from the dew of heaven above.
40 You will live by the sword
and you will serve your brother.
But when you grow restless,
you will throw his yoke
from off your neck."
Jacob Flees to Laban
41 Esau held a grudge against Jacob because of the blessing his father had given him. He said to himself, “The days of mourning for my father are near; then I will kill my brother Jacob.”
42 When Rebekah was told what her older son Esau had said, she sent for her younger son Jacob and said to him, “Your brother Esau is consoling himself with the thought of killing you. 43 Now then, my son, do what I say: Flee at once to my brother Laban in Haran. 44 Stay with him for a while until your brother’s fury subsides. 45 When your brother is no longer angry with you and forgets what you did to him, I’ll send word for you to come back from there. Why should I lose both of you in one day?”
