Exodus 23:28

²⁶  There shall nothing cast their young, nor be barren, in thy land: the number of thy days I will fulfil.

²⁷  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.

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

²⁹  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.

³⁰  By little and little I will drive them out from before thee, until thou be increased, and inherit the land.
