Hawk shows that the themes surrounding Joshua express fundamental markers of national identity: religious practice (obedience to the commandments of Moses), ethnic separation (extermination of the peoples of Canaan), and possession of land ("the land that YHWH gives"). Through the medium of narrative, Joshua tests each of these markers and demonstrates that none clearly characterize the people of God. Instead, Joshua presents Israel as a nation fundamentally constituted by choosing: YHWH's choosing of Israel and Israel's choosing of YHWH. (christianbook.com).
