Exodus 23:29-31

Revised Standard Version

²⁹ I will not drive them out from before you in one year, lest the land become desolate and the wild beasts multiply against you. ³⁰ Little by little I will drive them out from before you, until you are increased and possess the land. ³¹ And I will set your bounds from the Red Sea to the sea of the Philistines, and from the wilderness to the Euphra′tes; for I will deliver the inhabitants of the land into your hand, and you shall drive them out before you.
