God's Plan For A City Take Over

Exodus 23:27-33
 
27  I will send my fear before thee, and will destroy all the people to whom thou shalt come, and I will make all thine enemies turn their backs unto thee. 
28  And I will send hornets before thee, which shall drive out the Hivite, the Canaanite, and the Hittite, from before thee. 
29  I will not drive them out from before thee in one year; lest the land become desolate, and the beast of the field multiply against thee. 
30  By little and little I will drive them out from before thee, until thou be increased, and inherit the land. 
31  And I will set thy bounds from the Red sea even unto the sea of the Philistines, and from the desert unto the river: for I will deliver the inhabitants of the land into your hand; and thou shalt drive them out before thee. 
32  Thou shalt make no covenant with them, nor with their gods. 
33  They shall not dwell in thy land, lest they make thee sin against me: for if thou serve their gods, it will surely be a snare unto thee.
