Genesis 25:23-26

The LORD said to her, “Two nations are in your womb; And two peoples will be separated from your body; And one people shall be stronger than the other; And the older shall serve the younger.” When her days to be delivered were fulfilled, behold, there were twins in her womb. Now the first came forth red, all over like a hairy garment; and they named him Esau. Afterward his brother came forth with his hand holding on to Esau’s heel, so his name was called Jacob; and Isaac was sixty years old when she gave birth to them.
