Deuteronomy 9:3-5

Amplified Bible

³ So know today [with confident assurance] that the Lord your God is crossing [the Jordan] before you like a devouring fire. He will destroy them and He will subdue them before you, and you shall drive them out and destroy them quickly, just as the Lord has promised you.

⁴ “Do not say in your heart when the Lord your God has driven them out before you, ‘Because of my righteousness the Lord has brought me in to possess this land,’ but because of the wickedness of these nations the Lord is dispossessing them before you. ⁵ It is not for your righteousness or for the uprightness of your heart that you are going to possess their land, but because of the wickedness of these nations the Lord your God is driving them out before you, and to confirm the oath which the Lord swore to your fathers, to Abraham, Isaac, and Jacob.
