Exodus 23:23, 28-33

For my angel will go before you and bring you into the land of the Amorites, Hittites, Perizzites, Canaanites, Hivites, and Jebusites, so you may live there. And I will destroy them completely.

I will send terror ahead of you to drive out the Hivites, Canaanites, and Hittites. But I will not drive them out in a single year, because the land would become desolate and the wild animals would multiply and threaten you. I will drive them out a little at a time until your population has increased enough to take possession of the land. And I will fix your boundaries from the Red Sea to the Mediterranean Sea, and from the eastern wilderness to the Euphrates River. I will hand over to you the people now living in the land, and you will drive them out ahead of you. “Make no treaties with them or their gods. They must not live in your land, or they will cause you to sin against me. If you serve their gods, you will be caught in the trap of idolatry.”
