Genesis 25:29-32

Once when Jacob was cooking some stew, Esau came in from the open country, famished. He said to Jacob, “Quick, let me have some of that red stew! I’m famished!” (That is why he was also called Edom.) Jacob replied, “First sell me your birthright.” “Look, I am about to die,” Esau said. “What good is the birthright to me?”
