Deuteronomy

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.

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

But the wicked shall be cut off from the earth, and the transgressors shall be rooted out of it.

Now these are the nations which the Lord left, to prove Israel by them, even as many of Israel as had not known all the wars of Canaan;

And the Lord gave them rest round about, according to all that he sware unto their fathers: and there stood not a man of all their enemies before them; the Lord delivered all their enemies into their hand.
