Exodus 23:28-30

Amplified Bible

²⁸ I will send hornets ahead of you which shall drive out the Hivite, the Canaanite, and the Hittite before you. ²⁹ I will not drive them out before you in a single year, so that the land does not become desolate [due to lack of attention] and the [wild] animals of the field do not become too numerous for you. ³⁰ I will drive them out before you little by little, until you have increased and are strong enough to take possession of the land.
