Deuteronomy provides a retrospective on God's dealings with Israel in leading them out of Egypt, an introspective for Israel to understand God's laws and principles for living in covenant with him, and a prospective looking toward Israel's future in the promised land. Some key themes are the choice to love and obey God over other gods, emphasizing God as the sole deity, God bringing the Israelites out of Egypt to possess the promised land, and what it means to love God by fearing, obeying, and serving him with all one's heart. Moses delivers three sermons for the people before his death, reiterating God's faithfulness to the covenant despite Israel's failures.
