Deuteronomy, which means 'second law' derived from the Greek term deuteronomion, records Moses’ final exhortation to the nation of Israel on the plains of Moab as they stand ready to cross into the Promised Land without him. Yet this book is much more than a mere restatement of earlier laws; it is a fervent sermon that applies the Sinai covenant to a fresh generation confronting new circumstances. Here we see Moses not simply as a lawgiver but as a passionate preacher, urging Israel to embrace life, love God wholeheartedly, and faithfully transmit their devotion to future generations.
This book occupies a distinctive role within the biblical canon. It is the Old Testament book most frequently cited in the New Testament. Jesus Himself drew upon Deuteronomy to resist Satan’s temptations and identified its central command—to love God with all one’s heart—as the greatest commandment. The language of Deuteronomy, including terms like 'hear,' 'remember,' 'love,' 'obey,' and 'choose,' profoundly influences the theology of both the Old and New Testaments.
Structurally, Deuteronomy mirrors the ancient Near Eastern treaty format between a sovereign king and his vassal nation. God is portrayed as the supreme King who has redeemed Israel, and Israel are His covenant people bound by solemn obligations. This treaty framework consists of a preamble identifying the King, a historical prologue recounting past dealings, stipulations outlining the laws, blessings and curses detailing the consequences, and witnesses invoking heaven and earth.
Theologically, the book highlights the unity of God (expressed in the Shema), the primacy of love as the foundation for obedience, the peril of forgetting God amid prosperity, and the vital importance of passing faith to the next generation. It presents one of Scripture’s clearest calls to decision: 'I have set before you life and death, blessing and cursing; therefore choose life.' This summons resonates throughout all later revelation.
