Exodus 23:28-30

New Century Version

²⁸ I will send terror ahead of you that will force the Hivites, Canaanites, and Hittites out of your way. ²⁹ But I will not force all those people out in only one year. If I did, the land would become a desert and the wild animals would become too many for you. ³⁰ Instead, I will force those people out slowly, until there are enough of you to take over the land.
