Genesis 36:21

Seir the Horite was among the early people of the land. His descendants lived in that region until Esau and his descendants moved in and drove them out (Deuteronomy 2:12).

This passage begins a second account of Esau’s descendants (36:1). It introduces a new list of his family line and traces his descendants through later generations. It also records marriages and alliances

Genesis now turns to the story of Isaac’s sons. It first finishes the account of Esau’s line (chapter 36), who was not chosen. Then it continues with the line of Jacob (chapter 37), whom God chose.

Sons of Seir, the Horite--native dukes, who were incorporated with those of the Edomite race.

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. 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 (Gen 36:24), and yet is called duke Anah, Gen 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.

And these are the generations of Esau, the father of the Edomites [130] Though Esau had two names, yet in this place the second name refers to his posterity, who are called Idumeans. For, to make it appear what God had bestowed upon him for the sake of his father Isaac, Moses expressly calls him the father of a celebrated and famous people. And certainly, it served this purpose not a little, to trace the effect and fulfillment of the prophecy in the progeny of Esau. For if the promise of God so mightily flourished towards a stranger, how much more powerfully would it put itself forth towards the children, to whom pertaineth the adoption, and consequently the inheritance of grace? Esau was an obscure man, and a sojourner in that country: whence therefore is it, that suddenly rulers should spring from him, and a great body of people should flourish, unless because the benediction which proceeded from the mouth of Isaac, was confirmed by the result? For Esau did not reign in this desert without opposition; since a people of no ignoble name previously inhabited Mount Seir. On this account Moses relates that the men who had before inhabited that land were mighty: so that it would not have been easy for a stranger to acquire such power as Esau possessed, if he had not been divinely assisted.

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 Gen 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.

And Dishon, and Ezer, and Dishan,.... These were three others of the sons of Seir, which with the other four before mentioned made seven:

these are the dukes of the Horites, the children of Seir in the land of Edom; these were in the land of Edom before it was so called and possessed by the Edomites, and whose posterity afterwards became tributary to them.

(parallel, Ch1 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). Seven sons of Seir are given as tribe-princes of the Horites, who are afterwards mentioned as Alluphim (Gen 36:29, Gen 36:30), also their sons, as well as two daughters, Timna (Gen 36:22) and Aholibamah (Gen 36:25), who obtained notoriety from the face that two of the headquarters of Edomitish tribe-princes bore their names (Gen 36:40 and Gen 36:41). Timna was probably the same as the concubine of Eliphaz (Gen 36:12); but Aholibamah was not the wife of Esau (cf. Gen 36:2). - There are a few instances in which the names in this list differ from those in the Chronicles. But they are differences which either consist of variation in form, or have arisen from mistakes in copying.
(Note: Knobel also undertakes to explain these names geographically, and to point them out in tribes and places of Arabia, assuming, quite arbitrarily and in opposition to the text, that the names refer to tribes, not to persons, although an incident is related of Zibeon's son, which proves at once that the list relates to persons and not to tribes; and expecting his readers to believe that not only are the descendants of these troglodytes, who were exterminated before the time of Moses, still to be found, but even their names may be traced in certain Bedouin tribes, though more than 3000 years have passed away! The utter groundlessness of such explanations, which rest upon nothing more than similarity of names, may be seen in the association of Shobal with Syria Sobal (Judith 3:1), the name used by the Crusaders for Arabia tertia, i.e., the southernmost district below the Dead Sea, which was conquered by them. For notwithstanding the resemblance of the name Shobal to Sobal, no one could seriously think of connecting Syria Sobal with the Horite prince Shobal, unless he was altogether ignorant of the apocryphal origin of the former name, which first of all arose from the Greek or Latin version of the Old Testament, and in fact from a misunderstanding of Psa 60:2, where, instead צובה ארם, Aram Zobah, we find in the lxx Συριά Σοβάλ, and in the Vulg. Syria et Sobal.)
Of Anah, the son of Zibeon, it is related (Gen 36:24), that as he fed the asses of his father in the desert, he "found היּמם" - not "he invented mules," as the Talmud, Luther, etc., render it, for mules are פּרדים, and מצא does not mean to invent; but he discovered aquae calidae (Vulg.), either the hot sulphur spring of Calirrhoe in the Wady Zerka Maein (vid., Gen 10:19), or those in the Wady el Ahsa to the S.E. of the Dead Sea, or those in the Wady Hamad between Kerek and the Dead Sea.
(Note: It is possible that there may be something significant in the fact that it was "as he was feeding his father's asses," and that the asses may have contributed to the discovery; just as the whirlpool of Karlsbad is said to have been discovered through a hound of Charles IV, which pursued a stag into a hot spring, and attracted the huntsmen to the spot by its howling.)
