1. Summary of the Book
Deuteronomy is the book of covenant renewal, presenting Moses’ final teachings to Israel as they stand on the threshold of the Promised Land. After forty years of wandering, a new generation has arisen—one that did not experience the Exodus or the giving of the Law at Sinai directly. Moses, knowing he will not enter the land, instructs them with urgency, fatherly love, and prophetic authority. His words are both a recounting of God’s past deeds and a call to faithful obedience in the future.
The book consists of three major speeches by Moses. In the first, he reviews Israel’s history: the journey from Horeb, the rebellion at Kadesh-barnea, the years of wandering, victories over Sihon and Og, and the distribution of land east of the Jordan. Moses emphasizes how God carried Israel, fought for them, disciplined them, and remained faithful despite their failures.
In the second and largest discourse, Moses restates and expands the law given at Sinai. This includes the Ten Commandments, now addressed personally to the new generation. The heart of the book appears in the Shema: “Hear, O Israel: The LORD is our God, the LORD alone; you shall love the LORD your God with all your heart, soul, and strength.” Moses stresses that obedience must flow from love, not mere ritual. He warns against idolatry, instructs them to remember God’s deeds, and calls them to holiness, justice, and compassion—especially toward the poor, the widow, the orphan, and the foreigner.
Deuteronomy presents laws on worship, leadership, warfare, marriage, family, economics, festivals, and social ethics. It outlines the responsibilities of priests, judges, kings, and prophets. Moses also explains the blessings that will come from obedience and the curses that will follow disobedience. These blessings and curses form the covenant framework that shapes Israel’s future history.
The third discourse is a renewed covenant ceremony. Moses calls heaven and earth as witnesses, urging Israel to choose life by loving and obeying the Lord. Joshua is appointed as his successor. Moses then writes the law, entrusts it to the Levites, and commands that it be proclaimed publicly every seven years. The book ends with Moses’ final blessing of the tribes, his ascent of Mount Nebo, and his death. His prophetic legacy continues in Joshua, and Israel prepares to enter the Promised Land.
Deuteronomy is both a farewell and a new beginning—a book that gathers the entire meaning of Israel’s covenant life into a call to love, obedience, gratitude, remembrance, and fidelity. It becomes the theological backbone of the Old Testament and is central to Jesus’ own teaching.
2. Author
Traditionally attributed to Moses, who delivers the speeches recorded in the book. The final chapter describing Moses’ death was likely added by Joshua or another inspired writer. Catholic tradition upholds Mosaic authorship in substance and inspiration.
3. Time of Composition
The setting is the final days of Moses’ life, around the end of the wilderness period (13th or 15th century BC). The speeches were delivered on the plains of Moab before Israel crossed the Jordan into Canaan.
4. Intended Audience
The new generation of Israelites preparing to enter the Promised Land. Deuteronomy teaches them to remember God’s deeds, obey His commandments, and avoid the sins of their parents. It also serves as a permanent covenant document for all future generations of Israel.

7. Historical and Biblical Background
Deuteronomy reflects ancient covenant treaty forms used in the Near East, especially Hittite and Assyrian treaties. God appears as the divine King making a covenant with His people. The book stands at a pivotal point in Israel’s history, preparing them for a new life in the land. It also introduces theological themes—love of God, blessings and curses, covenant fidelity—that shape the entire biblical story. Deuteronomy heavily influences the prophets, wisdom literature, and historical books.
