Exodus 23:28-30

New International Version - UK

²⁸ I will send the hornet ahead of you to drive the Hivites, Canaanites and Hittites out of your way. ²⁹ But I will not drive them out in a single year, because the land would become desolate and the wild animals too numerous for you. ³⁰ Little by little I will drive them out before you, until you have increased enough to take possession of the land.
