Deuteronomy 9:3-5

Today know this: GOD, your God, is crossing the river ahead of you—he’s a consuming fire. He will destroy the nations, he will put them under your power. You will oust them and very quickly wipe them out, just as GOD promised you would. 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.
