The last of five Old Testament books known as the Books of the Law, or the Pentateuch or the Torah.
A new generation of Israelites was about to enter the Promised Land. This multitude had not experienced the miracle at the Red Sea or heard the law given at Sinai, and they were about to enter a new land with many dangers and temptations. The book of Deuteronomy was given to remind them of God’s law and God’s power.
The Israelites are commanded to remember four things: God’s faithfulness, God’s holiness, God’s blessings, and God’s warnings. The first three chapters recap the trip from Egypt to their current location, Moab. Chapter 4 is a call to obedience, to be faithful to the God Who was faithful to them.
Chapters 5 through 26 are a repetition of the law. The Ten Commandments, the laws concerning sacrifices and specials days, and the rest of the law are given to the new generation. Blessings are promised to those who obey (5:29; 6:17-19; 11:13-15), and famine is promised to those who break the law (11:16-17).
The theme of blessing and cursing is continued in chapters 27-30. This portion of the book ends with a clear choice set before Israel: “I have set before you life and death, blessing and cursing.” God’s desire for His people is found in what He recommends: “choose life” (30:19).
In the final chapters, Moses encourages the people; commissions his replacement, Joshua; records a song; and gives a final blessing to each of the tribes of Israel. Chapter 34 relates the circumstances of Moses’ death. He climbed Mt. Pisgah, where the Lord showed him the Promised Land that he could not enter. At 120 years old, but still with good eyesight and the strength of youth, Moses died in the presence of the Lord. The book of Deuteronomy ends with a short obituary on this great prophet.
