Deuteronomy 9:2-3

9:2 They include the Anakites, a numerous and tall people whom you know about and of whom it is said, “Who is able to resist the Anakites?” 9:3 Understand today that the Lord your God who goes before you is a devouring fire; he will defeat and subdue them before you. You will dispossess and destroy them quickly just as he has told you.
