Exodus 23:20-23

“Behold, I am going to send an angel before you to guard you along the way and to bring you into the place which I have prepared. Be on your guard before him and obey his voice; do not be rebellious toward him, for he will not pardon your transgression, since My name is in him. But if you truly obey his voice and do all that I say, then I will be an enemy to your enemies and an adversary to your adversaries. For My angel will go before you and bring you in to the land of the Amorites, the Hittites, the Perizzites, the Canaanites, the Hivites and the Jebusites; and I will completely destroy them.
