Genesis 25:23-26

23Adonai said to her: “Two nations are in your womb, and two peoples from your body will be separated. One people will be stronger than the other people, but the older will serve the younger.”

24When her time came to give birth, indeed there were twins in her womb.

25Now the first came out reddish, all of him was like a fur coat, and they named him Esau.

26Afterward his brother came out with his hand holding onto Esau’s heel—so he was named Jacob. Isaac was 60 years old when he fathered them.
