Exodus 23:28-30

American Standard Version

²⁸ And I will send the hornet 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 beasts 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.
