In the midst of this genealogy of the Edomites here is inserted the genealogy of the Horites, those Canaanites, or Hittites (compare Gen 26:34), that were the natives of Mount Seir. Mention is made of them, Gen 14:6, and of their interest in Mount Seir, before the Edomites took possession of it, Deu 2:12, Deu 2:22.

And these are the sons of Dishon,.... Not of Dishon the son of Anah, but of Dishon the son of Seir, Gen 36:21; and they are the four following: Hemdan, and Eshban, and Ithran, and Cheran; the first of these is called Amram, or rather Chamram, Ch1 1:41.
Gen 36:20-29 (parallel, 1Ch 1:38-42). Descendants of Seir the Horite; - the inhabitants of the land, or pre-Edomitish population of the country. - “The Horite:” ὁ Τρωγλοδύτης, the dweller in caves, which abound in the mountains of Edom (vid., Rob. Pal. ii. p. 424). The Horites, who had previously been an independent people (Gen 14:6), were partly exterminated and partly subjugated by the descendants of Esau (Deu 2:12, Deu 2:22).
