Genesis 25:24-26
24 When the time came for her to give birth, there were twin boys in her womb.
25 The first to come out was red, and his whole body was like a hairy garment; so they named him Esau.
26 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.
