'As A Possession' in the Bible

When you approach {the border of} the {Ammonites}, you shall not harass them, and you shall not get involved in battle with them, for I have not given the land of {the Ammonites} to you as a possession; because I have given it to the descendants of Lot [as] a possession.

You shall prepare the roads for yourselves, and you shall divide the regions of your land into thirds that Yahweh your God gives you as a possession, so that {it will be available for any manslayer to flee there}.
