In the midst of this genealogy of the Edomites here is inserted the genealogy of the Horites, those Canaanites, or Hittites (compare Genesis 26:34), that were the natives of Mount Seir. Mention is made of them, Genesis 14:6, and of their interest in Mount Seir, before the Edomites took possession of it, Deuteronomy 2:12.
This comes in here, not only to give light to the story, but to be a standing reflection upon the Edomites for intermarrying with them, by which, it is probable, they learned their way, and corrupted themselves.
Esau having sold his birthright, and lost his blessing, and entered into alliance with the Hittites, his posterity and the sons of Seir are here reckoned together. Note, Those that treacherously desert God's church are justly numbered with those that were never in it; apostate Edomites stand on the same ground with accursed Horites.
Particular notice is taken of one Anah who fed the asses of Zibeon his father (Genesis 36:24), and yet is called duke Anah, Genesis 36:29. Note, Those that expect to rise high should begin low. An honourable descent should not keep men from an honest employment, nor a mean employment hinder any man's preferment.
This Anah was not only industrious in his business, but ingenious too, and successful; for he found mules, or (as some read it) waters, hot-baths, in the wilderness. Those that are diligent in their business sometimes find more advantages than they expected.
