Genesis 25:27-34 - Esau Sells His Birthright
27 And the boys grew: and Esau was a skillful hunter, a man of the field; and Jacob was a plain man dwelling in tents. 28 And Isaac loved Esau, because he ate of his venison: but Rebekah loved Jacob.
29 And Jacob boiled 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 to me this day thy birth-right.
32 And Esau said, Behold, I am at the point to die: and what profit shall this birth-right bring to me?
33 And Jacob said, Swear to me this day; and he swore to him: and he sold his birth-right to Jacob. 34 Then Jacob gave Esau bread and pottage of lentiles; and he ate and drank, and rose and went his way: thus Esau despised his birth-right.
