Deuteronomy 9:3-5

New Catholic Bible

³ Understand, therefore, that the Lord, your God, is crossing over ahead of you like a devouring fire today. He will destroy them and bring them low before you. Therefore, you will be able to drive them out and annihilate them quickly, just as the Lord has promised you. ⁴ After the Lord, your God, has driven them out before you, do not say to yourself, “It was because of my righteousness that the Lord brought me in to take possession of this land.” It is because of the wickedness of the nations that the Lord is going to drive them out before you. ⁵ It is not because of your righteousness or the sincerity of your heart that you are going to take possession of their land. Rather, it is because of the wickedness of these nations that the Lord, your God, will drive them out before you, fulfilling the promise that he made to your fathers, to Abraham, Isaac, and Jacob.
