Exodus 23:27 WEB

²⁵  You shall serve Yahweh your God, and he will bless your bread and your water, and I will take sickness away from your midst.

²⁶  No one will miscarry or be barren in your land. I will fulfill the number of your days.

²⁷  I will send my terror before you, and will confuse all the people to whom you come, and I will make all your enemies turn their backs to you.

²⁸  I will send the hornet before you, which will 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 animals of the field multiply against you.
