Genesis 36:6-8

Esau gathered up his wives, sons and daughters, and everybody in his household, along with all his livestock—all the animals and possessions he had gotten in Canaan—and moved a considerable distance away from his brother Jacob. The brothers had too many possessions to live together in the same place; the land couldn’t support their combined herds of livestock. So Esau ended up settling in the hill country of Seir (Esau and Edom are the same).
