Exodus 33:2-4

33:2 I will send an angel before you, and I will drive out the Canaanite, the Amorite, the Hittite, the Perizzite, the Hivite, and the Jebusite. 33:3 Go up to a land flowing with milk and honey. But I will not go up among you, for you are a stiff-necked people, and I might destroy you on the way.”

33:4 When the people heard this troubling word they mourned; no one put on his ornaments.
