Exodus 23:26-30

There will be no one miscarrying or unable to have children in your land; I will fulfill the number of your days.

I will send My terror ahead of you, and throw into confusion all the people among whom you come, and I will make all your enemies turn their backs to you.

And I will send hornets ahead of you so that they will drive out the Hivites, the Canaanites, and the Hittites from you.

I will not drive them out from you in a single year, so that the land will not become desolate and the animals of the field become too numerous for you.

I will drive them out from you little by little, until you become fruitful and take possession of the land.
