And his father Isaac said to him, “Who are you?” So he said, “I am your son, your firstborn, Esau.”
So he went to his father and said, “My father.” And he said, “Here I am. Who are you, my son?”
Then Jacob said, “Swear to me as of this day.” So he swore to him, and sold his birthright to Jacob.
And Jacob gave Esau bread and stew of lentils; then he ate and drank, arose, and went his way. Thus Esau despised his birthright.
