The King James Version

28. And Isaac loved Esau, because he did eat of his venison; but Rebekah loved Jacob. 29. And Jacob sod pottage; and Esau came in 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 me? 33. And Jacob said, Swear to me this day: and he sware to him: and he sold his birthright unto Jacob. 34. Then Jacob gave Esau bread and a pottage of lentils; and he did eat and drink, and rose up, and went his way; thus Esau despised his birthright.

28. Yitzhak grew to love Esav, for (he brought) hunted game for his mouth, but Rivka loved Yaakov.
29. Once Yaakov was boiling boiled-stew, when Esav came in from the field, and he was
weary.
30. Esav said to Yaakov:
Pray give me a gulp of the red-stuff, that red-stuff, for I am so weary!
Therefore they called his name: Edom/
Red-One.
31. Yaakov said:
Sell me your firstborn-right here-and-now.
32. Esav said:
Here I am on my way to dying, so what good to me is a firstborn-right?
33. Yaakov said:
Swear to me here-and-now.
He swore to him and sold his firstborn-right to Yaakov.
34. Yaakov gave Esav bread and boiled lentils;
he ate and drank and arose and went off.
Thus did Esav despise the firstborn-right.

28. And Isaac loved Esau for the game that he brought him, but Rebekah loved Jacob. 29. And Jacob prepared a stew and Esau came from the field, and he was famished. 30. And Esau said to Jacob, “Let me gulp down some of this red red stuff, for I am famished.” Therefore is his name called Edom. 31. And Jacob said, “Sell now your birthright to me.” 32. And Esau said, “Look, I am at the point of death, so why do I need a birthright?” 33. And Jacob said, “Swear to me now,” and he swore to him, and he sold his birthright to Jacob. 34. Then Jacob gave Esau bread and lentil stew, and he ate and he drank and he rose and he went off, and Esau spurned the birthright.
