Exodus 23:25-29

And ye shall serve the LORD your God, and he shall bless thy bread, and thy water; and I will take sickness away from the midst of thee.

There shall nothing cast their young, nor be barren, in thy land: the number of thy days I will fulfil.

I will send my fear before thee, and will destroy all the people to whom thou shalt come, and I will make all thine enemies turn their backs unto thee.

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

I will not drive them out from before thee in one year; lest the land become desolate, and the beast of the field multiply against thee.
