Genesis 25:29 BBE

²⁷  And the boys came to full growth; and Esau became a man of the open country, an expert bowman; but Jacob was a quiet man, living in tents.

²⁸  Now Isaac's love was for Esau, because Esau's meat was greatly to his taste: but Rebekah had more love for Jacob.

²⁹  And one day Jacob was cooking some soup when Esau came in from the fields in great need of food;

³⁰  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.
