'Possess Their Land' in the Bible

Not for your righteousness, or for the uprightness of your heart, do you go in to possess their land; but for the wickedness of these nations Yahweh your God does drive them out from before you, and that he may establish the word which Yahweh swore to your fathers, to Abraham, to Isaac, and to Jacob.

Yahweh your God will thrust them out from before you, and drive them from out of your sight. You shall possess their land, as Yahweh your God spoke to you.
