Exodus 23
29 Ref I will not send them all out in one year, for fear that their land may become waste, and the beasts of the field be increased overmuch against you.
30 Little by little I will send them away before you, till your numbers are increased and you take up your heritage in the land.
31 Ref I will let the limits of your land be from the Red Sea to the sea of the Philistines, and from the waste land to the river Euphrates: for I will give the people of those lands into your power; and you will send them out before you.
