Genesis 25:24-28

When the time came for her to give birth, there were twin boys in her womb. The first to come out was red, and his whole body was like a hairy garment; so they named him Esau. After this, his brother came out, with his hand grasping Esau’s heel; so he was named Jacob. Isaac was sixty years old when Rebekah gave birth to them. The boys grew up, and Esau became a skilful hunter, a man of the open country, while Jacob was content to stay at home among the tents. Isaac, who had a taste for wild game, loved Esau, but Rebekah loved Jacob.
