Exodus 23:30-33

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. Thou shalt make no covenant with them, nor with their gods. 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.
