Deuteronomy 9:4-5

But when GOD pushes them out ahead of you, don’t start thinking to yourselves, “It’s because of all the good I’ve done that GOD has brought me in here to dispossess these nations.” Actually it’s because of all the evil these nations have done. No, it’s nothing good that you’ve done, no record for decency that you’ve built up, that got you here; it’s because of the vile wickedness of these nations that GOD, your God, is dispossessing them before you so that he can keep his promised word to your ancestors, to Abraham, Isaac, and Jacob.
