Genesis 27:3-5, 40

So now, please take your [hunting] gear, your quiver [of arrows] and your bow, and go out into the open country and hunt game for me; and make me a savory and delicious dish [of meat], the kind I love, and bring it to me to eat, so that my soul may bless you [as my firstborn son] before I die.” But Rebekah overheard what Isaac said to Esau his son; and when Esau had gone to the open country to hunt for game that he might bring back

But you shall live by your sword, And serve your brother; However it shall come to pass when you break loose [from your anger and hatred], That you will tear his yoke off your neck [and you will be free of him].”
