'Possession Of Their Land' in the Bible

[It is] not because of your righteousness and because of the uprightness of your heart [that] you [are] coming to take possession of their land, but because of the wickedness of these nations Yahweh your God [is] driving them {before you}, and in order to confirm the {promise} that Yahweh swore to your ancestors, to Abraham, to Isaac, and to Jacob.
