Deuteronomy 9:3-5

New Life Version

³ But know today that it is the Lord your God Who is crossing over before you as a fire that destroys everything. He will destroy them and bring them down before you. So you may drive them out and be quick to destroy them, just as the Lord has told you. ⁴ But after the Lord your God has driven them out before you, do not say in your heart, ‘The Lord has brought me in to take this land because I am right and good.’ It is because of the sin of these nations that the Lord is driving them out in front of you. ⁵ It is not because of your being right with God that you are going to take their land. But it is because of the sin of these nations that the Lord your God is driving them out in front of you. By this the Lord is proving that He keeps the promise He made to your fathers, to Abraham, Isaac and Jacob.
