Exodus 23:20-23

²⁰Behold, I send an Angel before thee, to keep thee in the way, and to bring thee into the place which I have prepared. ²¹Beware of him, and obey his voice, provoke him not; for he will not pardon your transgressions: for my name is in him. ²²But if thou shalt indeed obey his voice, and do all that I speak; then I will be an enemy unto thine enemies, and an adversary unto thine adversaries. ²³For mine Angel shall go before thee, and bring thee in unto the Amorites, and the Hittites, and the Perizzites, and the Canaanites, the Hivites, and the Jebusites: and I will cut them off.
