Genesis 25:27-34 - Esau Sells His Birthright
27 And the boys grew: and Esau was a cunning hunter, a man of the field; and Jacob was a plain man, dwelling in tents. 28 And Isaac loved Esau, because he did eat of his venison: but Rebekah loved Jacob.
29 And Jacob sod pottage: and Esau came from the field, and he was faint: 30 And Esau said to Jacob, Feed me, I pray thee, with that same red pottage; for I am faint: therefore was his name called Edom.
31 And Jacob said, Sell me this day thy birthright.
32 And Esau said, Behold, I am at the point to die: and what profit shall this birthright do to me?
33 And Jacob said, Swear to me this day; and he sware unto him: and he sold his birthright unto Jacob. 34 Then Jacob gave Esau bread and pottage of lentiles; and he did eat and drink, and rose up, and went his way: thus Esau despised his birthright.
