20.) And Isaac was forty years old when he took Rebekah to wife, the daughter of Bethuel the Syrian of Padanaram, the sister to Laban the Syrian.
21.) And Isaac intreated the LORD for his wife, because she was barren: and the LORD was intreated of him, and Rebekah his wife conceived.
22.) And the children struggled together within her; and she said, If it be so, why am I thus? And she went to enquire of the LORD.
23.) And the LORD said unto her, Two nations are in thy womb, and two manner of people shall be separated from thy bowels; and the one people shall be stronger than the other people; and the elder shall serve the younger.
24.) And when her days to be delivered were fulfilled, behold, there were twins in her womb.
25.) And the first came out red, all over like an hairy garment; and they called his name Esau.
26.) And after that came his brother out, and his hand took hold on Esau's heel; and his name was called Jacob: and Isaac was threescore years old when she bare them.
27.) And the boys grew: and Esau was a cunning hunter, a man of the field; and Jacob was a plain man, dwelling in tents.

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.

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