Genesis 25:24-28

So when her days were fulfilled for her to give birth, indeed there were twins in her womb. And the first came out red. He was like a hairy garment all over; so they called his name Esau. Afterward his brother came out, and his hand took hold of Esau’s heel; so his name was called Jacob. Isaac was sixty years old when she bore them. So the boys grew. And Esau was a skillful hunter, a man of the field; but Jacob was a mild man, dwelling in tents. And Isaac loved Esau because he ate of his game, but Rebekah loved Jacob.
