31. But Jacob said, "First sell me your birthright."
32. Esau said, "Behold, I am about to die; so of what use then is the birthright to me?"
33. And Jacob said, "First swear to me"; so he swore to him, and sold his birthright to Jacob.
34. Then Jacob gave Esau bread and lentil stew; and he ate and drank, and rose and went on his way. Thus Esau despised his birthright.
