Deuteronomy 9:1-5

1Hear, Israel: You are now about to cross the Jordan to go in and dispossess nations greater and stronger than you, with large cities that have walls up to the sky. 2The people are strong and tall—Anakites! You know about them and have heard it said: “Who can stand up against the Anakites?” 3But be assured today that the Lord your God is the one who goes across ahead of you like a devouring fire. He will destroy them; he will subdue them before you. And you will drive them out and annihilate them quickly, as the Lord has promised you. 4After the Lord your God has driven them out before you, do not say to yourself, “The Lord has brought me here to take possession of this land because of my righteousness.” No, it is on account of the wickedness of these nations that the Lord is going to drive them out before you. 5It is not because of your righteousness or your integrity that you are going in to take possession of their land; but on account of the wickedness of these nations, the Lord your God will drive them out before you, to accomplish what he swore to your fathers, to Abraham, Isaac and Jacob.
