Deuteronomy 9:4-5

4The Lord your God will chase them away. After he has done that, be careful! Do not say to yourselves, ‘The Lord has brought us into this land because we do right things.’ No! It is because these nations are doing wicked things. That is why the Lord is chasing them out of the land so that you can live there.

5It is not because you are doing right things. It is not because you are good, honest people. That is not the reason that you will take their land for yourselves. Instead, it is because these nations are wicked people. That is why the Lord your God will chase them away as you move in there. He will do what he promised to your ancestors, Abraham, Isaac and Jacob.
