Genesis 25:21-27

   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 inquire 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.
