Deuteronomy 9:3-5

New Revised Standard Version, Anglicised Catholic Edition

³ Know then today that the Lord your God is the one who crosses over before you as a devouring fire; he will defeat them and subdue them before you, so that you may dispossess and destroy them quickly, as the Lord has promised you.

⁴ When the Lord your God thrusts them out before you, do not say to yourself, ‘It is because of my righteousness that the Lord has brought me in to occupy this land’; it is rather because of the wickedness of these nations that the Lord is dispossessing them before you. ⁵ It is not because of your righteousness or the uprightness of your heart that you are going in to occupy their land; but because of the wickedness of those nations that the Lord your God is dispossessing them before you, in order to fulfil the promise that the Lord made on oath to your ancestors, to Abraham, to Isaac, and to Jacob.
