Genesis 25
31 And Jacob said, Sell me first thy birthright.
32 Ref And Esau said, Behold, I am about to die. And what profit shall the birthright do to me?
33 Ref And Jacob said, Swear to me first. And he sware unto him. And he sold his birthright unto Jacob.
34 Ref And Jacob gave Esau bread and pottage of lentils. And he did eat and drink, and rose up, and went his way. So Esau despised his birthright.
