Genesis 25:24-26, 30

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.

He said to Jacob, “Quick, let me have some of that red stew! I’m famished!” (That is why he was also called Edom.)
