Genesis 25:28-32

And Isaac loved Esau, because he did eat of his venison: but Rebekah loved Jacob.

And Jacob sod pottage: and Esau came from the field, and he was faint:

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.

And Jacob said, Sell me this day thy birthright.

And Esau said, Behold, I am at the point to die: and what profit shall this birthright do to me?
