Exodus 23:25-29

And you shall serve the Lord your God, and He will bless your bread and your water; and I will remove sickness from your midst.

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.
