Genesis 25:34 WEB

³²  Esau said, 'Behold, I am about to die. What good is the birthright to me?'

³³  Jacob said, 'Swear to me first.' He swore to him. He sold his birthright to Jacob.

³⁴  Jacob gave Esau bread and stew of lentils. He ate and drank, rose up, and went his way. So Esau despised his birthright.
