Deuteronomy 9:5

For the wickedness of these nations - So then it was not by any sovereign act of God that these people were cast out, but for their wickedness; they had transgressed the law of their Creator; they had resisted his Spirit, and could no longer be tolerated. The Israelites were to possess their land, not because they deserved it, but first, because they were less wicked than the others; and secondly, because God thus chose to begin the great work of his salvation among men. Thus then the Canaanites were cut off, and the Israelites were grafted in; and the Israelites, because of their wickedness, were afterwards cut off and the Gentiles grafted in. Let the latter not be high-minded, but fear; if God spared not the natural branches, take heed lest he spare not thee. But let it be remembered that this land was originally their own, and that the present possessors had no legal right to it.
