Exodus 23:20-31

Behold, I send an angel before thee, to keep thee by the way, and to bring thee into the place which I have prepared. Take ye heed before him, and hearken unto his voice; provoke him not; for he will not pardon your transgression: for my name is in him. But if thou shalt indeed hearken unto his voice, and do all that I speak; then I will be an enemy unto thine enemies, and an adversary unto thine adversaries. For mine angel shall go before thee, and bring thee in unto the Amorite, and the Hittite, and the Perizzite, and the Canaanite, the Hivite, and the Jebusite: and I will cut them off. Thou shalt not bow down to their gods, nor serve them, nor do after their works; but thou shalt utterly overthrow them, and break in pieces their pillars. And ye shall serve Jehovah your God, and he will bless thy bread, and thy water; and I will take sickness away from the midst of thee. There shall none cast her young, nor be barren, in thy land: the number of thy days I will fulfil. I will send my terror before thee, and will discomfit all the people to whom thou shalt come, and I will make all thine enemies turn their backs unto thee. And I will send the hornet before thee, which shall drive out the Hivite, the Canaanite, and the Hittite, from before thee. I will not drive them out from before thee in one year, lest the land become desolate, and the beasts of the field multiply against thee. By little and little I will drive them out from before thee, until thou be increased, and inherit the land. And I will set thy border from the Red Sea even unto the sea of the Philistines, and from the wilderness unto the River: for I will deliver the inhabitants of the land into your hand: and thou shalt drive them out before thee.
