Charles Ellicott Commentary Genesis 35:29

"And Isaac gave up the ghost, and died, and was gathered unto his people, old and full of days: and Esau and Jacob his sons buried him." — Genesis 35:29 (ASV)

Esau and Jacob buried him. —Esau, who apparently still dwelt at Hebron until his father’s death, here takes precedence as his natural right. But having learned in previous expeditions the physical advantages of the land of Seir, and the powerlessness of the Horites to resist him, he gives up Hebron to his brother and migrates with his large wealth to that country.
