Genesis 25:32-34

Young's Literal Translation

³² And Esau saith, `Lo, I am going to die, and what is this to me -- birthright?'

³³ and Jacob saith, `Swear to me to-day:' and he sweareth to him, and selleth his birthright to Jacob;

³⁴ and Jacob hath given to Esau bread and pottage of lentiles, and he eateth, and drinketh, and riseth, and goeth; and Esau despiseth the birthright.
