Exodus 23:26-30 New King James Version (NKJV)

26. No one shall suffer miscarriage or be barren in your land; I will fulfill the number of your days.

27. “I will send My fear before you, I will cause confusion among all the people to whom you come, and will make all your enemies turn their backs to you.

28. And I will send hornets before you, which shall drive out the Hivite, the Canaanite, and the Hittite from before you.

29. I will not drive them out from before you in one year, lest the land become desolate and the beasts of the field become too numerous for you.

30. Little by little I will drive them out from before you, until you have increased, and you inherit the land.
