Exodus 23:27-31

27“I will send my terror ahead of you and create panic among all the people whose lands you invade. I will make all your enemies turn and run.

28I will send terror ahead of you to drive out the Hivites, Canaanites, and Hittites.

29But 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.

30I will drive them out a little at a time until your population has increased enough to take possession of the land.

31And 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.
