Genesis 36:21

These are the dukes of the Horites - It appears pretty evident that the Horites and the descendants of Esau were mixed together in the same land, as before observed; and Calmet has very properly remarked, that if we compare this verse with Genesis 36:30 , there were princes of Seir in the country of Seir, and in that of Edom; and in comparing the generations of Seir and Esau, we are obliged to consider these princes as contemporary.
