Genesis 25:23-26

23And Jehovah said to her, Two nations are in thy womb, And two peoples shall be separated from thy bowels; And one people shall be stronger than the other people, And the elder shall serve the younger.

24And when her days to be delivered were fulfilled, behold, there were twins in her womb.

25And the first came out red — all over like a hairy garment; and they called his name Esau.

26And after that came his brother out; and his hand took hold of Esau's heel; and his name was called Jacob. And Isaac was sixty years old when they were born.
