Deuteronomy 9:1, 5

“Hear, O Israel: you are to cross over the Jordan today, to go in to dispossess nations greater and mightier than you, cities great and fortified up to heaven

Not because of your righteousness or the uprightness of your heart are you going in to possess their land, but because of the wickedness of these nations the LORD your God is driving them out from before you, and that he may confirm the word that the LORD swore to your fathers, to Abraham, to Isaac, and to Jacob.
