Genesis 25:24-28

When her days to be delivered were fulfilled, behold, there were twins in her womb. The first came out reddish all over like a hairy garment; and they named him Esau (hairy). Afterward his brother came out, and his hand grasped Esau’s heel, so he was named Jacob (one who grabs by the heel, supplanter). Isaac was sixty years old when Rebekah gave birth to them. When the boys grew up, Esau was an able and skilled hunter, a man of the outdoors, but Jacob was a quiet and peaceful man, living in tents. Now Isaac loved [and favored] Esau, because he enjoyed eating his game, but Rebekah loved [and favored] Jacob.
