Isaac is dying of old age, and going blind. He sends Esau to hunt for some venison to make his favourite meal for him to eat, one last time before he dies. Rebekah overhears the instruction. She summons Jacob to bring her two goats from the flocks, from which she will make as good a stew for Isaac as Esau would be able to prepare. (Verses 1-10).
Isaac demurs saying that he is not as hairy as Esau, and that his father won’t be fooled by their deceit. To achieve the deception, Rebekah uses the goat skins to make a cover for his arms. Isaac eats the food, is satsified, and blesses Jacob as his heir. When Esau returns with his offering to his father, he is too late. The blessing cannot be withdrawn. Isaac is thus named the heir of his father’s wealth (Verses 11-30).
Esau expresses his intention to kill Isaac once his father has died. Rebekah, hearing this, tells Jacob to leave. She says to go to her brother Laban, and there to hide for a few days until Esau has calmed down. She tells Isaac she has sent Jacob away so that he won’t be tempted to marry a Hittite, a daughter of Heth, as Esau had done in the previous chapter (Verses 31-46).
This story is a continuation of the sibling feud that begun with Cain and Abel, with the variation that Esau is disinherited because Isaac was able to dupe their father into blessing him as his heir.
There’s really not much more I can say about this, except that it continues with the mythology to fuel dissent in families, with the approval of the patriarchs, and, by association, the approval of the deity they worship.
We see this approval later in the New Testament when Jesus tells his followers to leave their families and follow him.
Luke 14:26 If anyone comes to me and does not hate father and mother, wife and children, brothers and sisters–yes, even their own life–such a person cannot be my disciple.Matthew 10:37 Anyone who loves their father or mother more than me is not worthy of me; anyone who loves their son or daughter more than me is not worthy of me.
Thus we see that the incitement of hatred between siblings, whether they are Cain and Abel or Esau and Jacob, is rife in the Bible. Loving families, who support each other, share their success with each other, and who live together in peace, are not encouraged by the mythology in the Bible.
