Deuteronomy 9:1-5

“Hear, Israel! You are crossing the Jordan today, to go in to dispossess nations greater and mightier than you, cities that are great and fortified to heaven,

a people who are great and tall, the sons of the Anakim, whom you know and of whom you have heard it said, ‘Who can stand against the sons of Anak?’

So be aware today that it is the Lord your God who is crossing over ahead of you as a consuming fire. He will destroy them and He will subdue them before you, so that you may drive them out and eliminate them quickly, just as the Lord has spoken to you.

“Do not say in your heart when the Lord your God has driven them away from you, ‘Because of my righteousness the Lord has brought me in to take possession of this land.’ Rather, it is because of the wickedness of these nations that the Lord is dispossessing them before you.

It is not because of your righteousness or the uprightness of your heart that you are going in to take possession of their land, but it is because of the wickedness of these nations that the Lord your God is driving them out from before you, and in order to confirm the oath which the Lord swore to your fathers, to Abraham, Isaac, and Jacob.
