Genesis 25:24-26, 30

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.

And Esau said to Jacob, “Please feed me with that same red stew, for I am weary.” Therefore his name was called Edom.
