Genesis 36:6-8

Esau took his wives, his sons, his daughters, and all the people who lived with him, his herds and other animals, and all the belongings he had gotten in Canaan, and he went to a land away from his brother Jacob. Esau and Jacob’s belongings were becoming too many for them to live in the same land. The land where they had lived could not support both of them, because they had too many herds. So Esau lived in the mountains of Edom. (Esau is also named Edom.)
