Exodus 33:2-3

And I will send an angel before you, driving out the Canaanite and the Amorite and the Hittite and the Perizzite and the Hivite and the Jebusite: Go up to that land flowing with milk and honey; but I will not go up among you, for you are a stiff-necked people, for fear that I send destruction on you while you are on the way.
