Genesis 25:24-26 HCSB
When her time came to give birth, there were indeed twins in her womb. The first one came out red-looking, covered with hair like a fur coat, and they named him Esau. After this, his brother came out grasping Esau’s heel with his hand. So he was named Jacob. Isaac was 60 years old when they were born.
