Deuteronomy 9:5-7

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. 6Understand, then, that it is not because of your righteousness that the Lord your God is giving you this good land to possess, for you are a stiff-necked people. 7Remember this and never forget how you aroused the anger of the Lord your God in the wilderness. From the day you left Egypt until you arrived here, you have been rebellious against the Lord.
