Context Reading
31“First sell me your birthright,” Jacob replied. 32“Look,” said Esau, “I am about to die, so what good is a birthright to me?” 33“Swear to me first,” Jacob said. So Esau swore to Jacob and sold him the birthright. 34Then Jacob gave some bread and lentil stew to Esau, who ate and drank and then got up and went away. Thus Esau despised his birthright.
