Genesis 25:25-26

25The first to come out was red, and his whole body was like a hairy garment; so they named him Esau. Esau may mean hairy.

26After this, his brother came out, with his hand grasping Esau’s heel; so he was named Jacob. Jacob means he grasps the heel, a Hebrew idiom for he deceives. Isaac was sixty years old when Rebekah gave birth to them.
