Deuteronomy 7:22

“I will not drive them out before you in a single year, lest the land become desolate and the beasts of the field become too numerous for you.

“I will drive them out before you little by little, until you become fruitful and take the land as an inheritance.

‘If you walk in My statutes and keep My commandments so as to do them,

“Now it will be, if you diligently listen to the voice of Yahweh your God, being careful to do all His commandments which I am commanding you today, Yahweh your God will set you high above all the nations of the earth.
