Genesis 25:34 DBY

³²  And Esau said, Behold, I am going to die, and of what use can the birthright be to me?

³³  And Jacob said, Swear unto me now. And he swore unto him, and sold his birthright to Jacob.

³⁴  And Jacob gave Esau bread and the dish of lentils; and he ate and drank, and rose up and went away. Thus Esau despised the birthright.
