Deuteronomy 9:4-5

4“1Do not say in your heart when the Lord your God has driven them away from 2you, ‘Because of my righteousness the Lord has brought me in to take possession of this land.’ Rather, it is 3because of the 4wickedness of these nations that the Lord is dispossessing them before you. 5It is 5not because of your righteousness or the uprightness of your heart that you are going in to take possession of their land, 6but it is because of the 7wickedness of these nations that the Lord your God is driving them out from before you, and in order to confirm 8the 9oath which the Lord swore to your fathers, to Abraham, Isaac, and Jacob.
