Deuteronomy 9:4-5

4When the Lord your God drives them out before you, do not say to yourself, ‘The Lord brought me in to take possession of this land because of my righteousness.’ Instead, the Lord will drive out these nations before you because of their wickedness.

5You are not going to take possession of their land because of your righteousness or your integrity. Instead, the Lord your God will drive out these nations before you because of their wickedness, in order to fulfill the promise he swore to your ancestors Abraham, Isaac, and Jacob.
