Commentaries:
Esau had built up a considerable following, amassing an army of 400 men (Genesis 32:6; 33:1). Obviously, over such a short time, these men could not all have been Esau's direct descendants or even all his servants. We can deduce their identity by assembling the clues found in Genesis 36:2, 8, 20, and 24. Evidently, Esau's wife "Aholibamah, the daughter of Anah, the daughter of Zibeon the Hivite" (verses 1, 24) was also a Horite, who were the people who "inhabited the land" of Seir (verse 20). When Esau migrated to Seir (verse 8), he essentially went to live with his Horite wife's family, aristocrats of the area (verses 29-30). Many of the 400 men, then, were probably Horites, relatives of Esau's wife.
