Augustine of Hippo : ON THE LAND OF EDOM, OTHERWISE IDUMAEA. — The words of the Scripture: These are the rulers of the Horrhite, the son of Seir, in the land of Edom , they refer to the time in which the author lived. For when Seir, who begat them, dwelt there, before Esau came to that land, it was evidently not yet called the land of Edom. It is clear that it was none other than Esau who gave the name to that land, since the same person was named Esau and Edom. And from him the origin of the Idumeans, that is, the nation of Edom.
