Genesis 25
29 Ref And one day Jacob was cooking some soup when Esau came in from the fields in great need of food;
30 Ref And Esau said to Jacob, Give me a full meal of that red soup, for I am overcome with need for food: for this reason he was named Edom.
31 And Jacob said, First of all give me your birthright.
32 Ref And Esau said, Truly, I am at the point of death: what profit is the birthright to me?
33 Ref And Jacob said, First of all give me your oath; and he gave him his oath, handing over his birthright to Jacob.
34 Ref Then Jacob gave him bread and soup; and he took food and drink and went away, caring little for his birthright.
