Genesis 25
29 Ref Jacob boiled stew. Esau came in from the field, and he was famished.
30 Ref Esau said to Jacob, "Please feed me with that same red stew, for I am famished." Therefore his name was called Edom.
31 Jacob said, "First, sell me your birthright."
32 Ref Esau said, "Behold, I am about to die. What good is the birthright to me?"
33 Ref Jacob said, "Swear to me first." He swore to him. He sold his birthright to Jacob.
34 Ref Jacob gave Esau bread and stew of lentils. He ate and drank, rose up, and went his way. So Esau despised his birthright.
