Genesis 25:24-28

When her time to give birth came, sure enough, there were twins in her womb. The first came out reddish, as if snugly wrapped in a hairy blanket; they named him Esau (Hairy). His brother followed, his fist clutched tight to Esau’s heel; they named him Jacob (Heel). Isaac was sixty years old when they were born. The boys grew up. Esau became an expert hunter, an outdoorsman. Jacob was a quiet man preferring life indoors among the tents. Isaac loved Esau because he loved his game, but Rebekah loved Jacob.
