Exodus 23:28-30

Webster(i) 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 should become desolate, and the beast of the field should multiply against thee. 30 By little and little I will drive them out from before thee, until thou shalt be increased and inherit the land.
