Genesis 25:27-34

When the young men grew up, Esau became an outdoorsman who knew how to hunt, and Jacob became a quiet man who stayed at home. Isaac loved Esau because he enjoyed eating game, but Rebekah loved Jacob. Once when Jacob was boiling stew, Esau came in from the field hungry and said to Jacob, “I’m starving! Let me devour some of this red stuff.” That’s why his name is Edom. Jacob said, “Sell me your birthright today.” Esau said, “Since I’m going to die anyway, what good is my birthright to me?” Jacob said, “Give me your word today.” And he did. He sold his birthright to Jacob. So Jacob gave Esau bread and lentil stew. He ate, drank, got up, and left, showing just how little he thought of his birthright.
