Exodus 33:1-3

And Jehovah spake unto Moses, Depart, go up hence, thou and the people that thou hast brought up out of the land of Egypt, unto the land of which I sware unto Abraham, to Isaac, and to Jacob, saying, Unto thy seed will I give it: and I will send an angel before thee; and I will drive out the Canaanite, the Amorite, and the Hittite, and the Perizzite, the Hivite, and the Jebusite: unto a land flowing with milk and honey: for I will not go up in the midst of thee, for thou art a stiffnecked people, lest I consume thee in the way.
