I have given mount Seir unto Esau — It is worthy of notice that the development of Ishmael preceded that of Isaac, and the inheritance of Esau was won earlier than that of Jacob. (Comp. Genesis 25:16 with Genesis 35:23-26, and Genesis 36:31 with Genesis 37:1.) Isaac and Israel were still strangers and sojourners, while the Ishmaelites were princes, with towns and castles, and the Edomites dukes and kings.
