His father Isaac said to him, “Who are you?” He answered, “I am your son, your firstborn, Esau.”
So he went in to his father and said, “My father.” And he said, “Here I am. Who are you, my son?”
Jacob said, “Swear to me now.” So he swore to him and sold his birthright to Jacob.
Then Jacob gave Esau bread and lentil stew, and he ate and drank and rose and went his way. Thus Esau despised his birthright.
