Deuteronomy 9:4-5

4“After Adonai your God has driven them out from before you, do not say in your heart, ‘It is because of my righteousness that Adonai has brought me in to possess this land.’ It is because of the wickedness of these nations that Adonai is driving them out from before you.

5It is not by your righteousness or the uprightness of your heart that you are going in to possess their land. Rather, because of the wickedness of these nations, Adonai your God is driving them out from before you, and in order to keep the word Adonai swore to your fathers—to Abraham, to Isaac, and to Jacob.
