Exodus 23:27-31

27“I will send My terror before you and throw all the people to whom you will come into panic, and make all your enemies turn their backs to you.

28I will send the hornet before you, which will drive out the Hivites, the Canaanites and the Hittites, from before you.

29I will not drive them out from before you in a single year. Otherwise the land would become desolate, and the animals of the field will multiply against you.

30But little by little I will drive them out from before you, until you are fruitful. Then you will possess the land.

31“I will set your border from the Sea of Reeds to the sea of the Philistines, and from the wilderness to the Euphrates River. For I will deliver the inhabitants of the land into your hand, and you are to drive them out before you.
