Genesis 25
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.
