Deuteronomy 31 is the chapter where Moses, at the age of one hundred twenty, passes leadership of Israel to Joshua and entrusts the law to the priests and elders. People read it to understand what Moses was doing in these final hours, why he insisted that God himself would go before Israel, and how the chapter sets up the story of the conquest of Canaan. It also contains a song and a warning that shape how the rest of the Old Testament is heard.
Deuteronomy 31 Summary
The chapter opens with Moses telling all Israel that he is too old to lead them any longer and that he will not cross the Jordan. He reassures the people that the LORD their God will go ahead of them and destroy the nations in the land, and he commissions Joshua in front of everyone with the same words of courage.
The scene then moves to the Tent of Meeting, where the LORD speaks to Moses about the future. God foresees that the people will turn to foreign gods after they settle in the land, and he gives Moses a song to teach them so that it will testify against their unfaithfulness when trouble arrives. Moses writes the song down, teaches it, and finishes writing the law.
The chapter closes with Moses instructing the Levites to place the book of the law beside the ark of the covenant as a witness, and he gathers the leaders to hear his final warning. He knows their stubbornness and predicts their failure, and he calls heaven and earth to witness what he has said.
Background and Setting
Deuteronomy is the fifth book of the Pentateuch and takes the form of Moses’ farewell addresses to Israel on the plains of Moab, just before they enter Canaan. Jewish and Christian tradition has long attributed the book to Moses, though many scholars today see it as shaped over centuries from older materials, with its final form often dated to the period of the late monarchy or the exile. The chapter itself presents itself as the close of Moses’ ministry.
The audience is the generation that came out of Egypt as a community now standing at the edge of promise, along with their children who had not witnessed the wilderness events. Chapter 31 sits between the great sermons of chapters 29 and 30 and the poetic blessing of chapter 33, marking the transition from Moses’ leadership to the leadership of Joshua and the priests.
Deuteronomy 31 Section by Section
Verses 1-6: The Leader Who Will Not Cross Over
2 He said to them, “I am one hundred twenty years old today. I can no more go out and come in. The LORD has said to me, ‘You shall not go over this Jordan.’ 3 The LORD your God himself will go over before you. He will destroy these nations from before you, and you shall dispossess them. Joshua will go over before you, as the LORD has spoken.
Deuteronomy 31:2-3 (WEB)
Moses begins by telling Israel plainly that he is one hundred twenty years old and can no longer go out and come in as before. He does not hide the fact that God has told him he will not enter the land. Instead of focusing on his own absence, he points the people to the LORD who will himself go over the Jordan ahead of them. The reassurance is practical as well as spiritual: God will clear the nations and Joshua will lead as God has spoken.
The section ends with a call to courage that is anchored in God’s presence rather than in human strength. Moses tells the people not to fear because the LORD their God is the one who goes with them and will not fail or forsake them. This is the first of several places in the chapter where the promise of God’s presence replaces the need for a human guarantee.
Verses 7-8: Joshua Commissioned Before the People
7 Moses called to Joshua, and said to him in the sight of all Israel, “Be strong and courageous, for you shall go with this people into the land which the LORD has sworn to their fathers to give them; and you shall cause them to inherit it. 8 The LORD himself is who goes before you. He will be with you. He will not fail you nor forsake you. Don’t be afraid. Don’t be discouraged.”
Deuteronomy 31:7-8 (WEB)
Moses calls Joshua in the sight of all Israel and gives him the same charge he has just given the people, to be strong and courageous. The public setting matters, because leadership passes from one man to another under the eyes of the community that must follow him. Moses ties Joshua’s task to the oath God made to their ancestors, so that the conquest is presented as fulfillment rather than personal ambition.
The repetition of the promises in these verses is deliberate. Moses says again that the LORD goes before them, will be with them, and will not fail or forsake them. For a people who had seen their former leader die, these words offered a steady foundation for the transition.
Verses 9-13: The Law Entrusted to the Priests
10 Moses commanded them, saying, “At the end of every seven years, in the set time of the year of release, in the feast of tents, 11 when all Israel has come to appear before the LORD your God in the place which he will choose, you shall read this law before all Israel in their hearing. 12 Assemble the people, the men and the women and the little ones, and the foreigners who are within your gates, that they may hear, and that they may learn, and fear the LORD your God, and observe to do all the words of this law…
Deuteronomy 31:10-12 (WEB)
Moses writes the law and gives it to the priests and elders, the keepers of the ark. He then commands that the law be read aloud every seven years at the feast of tents, when all Israel gathers before the LORD. The reading includes men, women, children, and foreigners living among them, so that everyone hears the same instruction.
The purpose stated in these verses is learning and reverence. The people are to hear the law so that they may learn to fear the LORD and keep his words, and so that the next generation, who did not witness the wilderness events, will grow up knowing the same God and the same commands. Scripture is presented here as something the community repeatedly hears together, not as a private possession.
Verses 14-18: God’s Warning in the Tent of Meeting
16 The LORD said to Moses, “Behold, you shall sleep with your fathers. This people will rise up, and play the prostitute after the strange gods of the land, where they go to be among them, and will forsake me, and break my covenant which I have made with them. 17 Then my anger shall be kindled against them in that day, and I will forsake them, and I will hide my face from them, and they shall be devoured, and many evils and troubles shall come on them; so that they will say in that day, ‘Haven’t these evils come on us because our God is not among us?’
Deuteronomy 31:16-17 (WEB)
The LORD speaks to Moses in the Tent of Meeting, where the pillar of cloud appears at the door. God tells Moses that he will soon die and that the people will turn to other gods once they are settled in the land. The passage is sober and does not soften the prediction that Israel will break the covenant and suffer the consequences.
These verses show that God knew the future failure of his people from the start. Yet the warning is not a statement that the relationship is over. It is an honest account of human unfaithfulness set alongside God’s continued commitment, which the rest of the chapter goes on to address through the song and the book of the law.
Verses 19-22: The Song as a Witness
19 “Now therefore write this song for yourselves, and teach it to the children of Israel. Put it in their mouths, that this song may be a witness for me against the children of Israel. 20 For when I have brought them into the land which I swore to their fathers, flowing with milk and honey, and they have eaten and filled themselves, and grown fat; then they will turn to other gods, and serve them, and despise me, and break my covenant. 21 It will happen, when many evils and troubles have come on them, that this song will testify before them as a witness; for it will not be forgotten out of the mouths of their descendants; for I know their ways and what they are doing today, before I have brought them into the land which I swore.”
Deuteronomy 31:19-21 (WEB)
God instructs Moses to write a song and teach it to Israel so that it will stand as a witness against them when trouble comes. Moses writes it that same day and teaches it to the people. The song is intended to be remembered, passed from mouth to mouth, so that even in the day of failure the people will recall what God said would happen.
The idea of a song as testimony is striking because it places memory and worship at the center of covenant faithfulness. The people are not left to reconstruct their obligations from scratch; they carry with them a melody that exposes their own patterns and calls them back. Verse 21 also reminds the reader that God knows their ways before they arrive.
Verses 23-30: The Book Beside the Ark
26 “Take this book of the law, and put it by the side of the ark of the LORD your God’s covenant, that it may be there for a witness against you. 27 For I know your rebellion, and your stiff neck. Behold, while I am yet alive with you today, you have been rebellious against the LORD. How much more after my death?
Deuteronomy 31:26-27 (WEB)
Moses finishes writing the law in a book and commands the Levites to place it beside the ark of the covenant as a witness against Israel. He acknowledges their rebellion and stiff necks, saying that they have been rebellious even while he is still alive. He gathers the elders and officers so that he can speak these words directly to them and call heaven and earth to witness.
The chapter ends on a note of serious warning. Moses predicts that after his death the people will corrupt themselves and turn from God’s way, and evil will come upon them in the latter days. The final verse introduces the song that will follow in chapter 32, which Moses speaks in the hearing of the whole assembly until it is finished.
Key Themes in Deuteronomy 31
- Divine presence: The LORD repeatedly promises to go before Israel, be with them, and never fail or forsake them, grounding courage in God rather than in human ability.
- Leadership transition: Moses hands authority to Joshua in public, showing that God’s work continues beyond the life of any single leader.
- The written word: The law is written, read aloud, and placed beside the ark so that it can serve as a standing witness for the community.
- Memory and song: The song is designed to be remembered and sung, so that the people will recall God’s warnings when they most need them.
- Human unfaithfulness: The chapter does not hide the people’s stubbornness and predicted failure, yet it frames that failure within God’s faithful commitment.
Lessons From Deuteronomy 31 for Today
Many people today face a season of handing something over, whether it is a parent stepping back from a family business, a long-serving volunteer preparing to leave a ministry, or a grandparent watching a younger generation take the lead. Moses’ example shows that it is possible to release responsibility honestly, admit limits, and still express confidence that the work will continue in God’s hands.
The chapter also speaks to the ordinary habit of reading the same Scripture again and again. Many families and congregations gather weekly or yearly to hear the same texts, and Moses’ instruction to read the law to everyone, including children, reminds us that repetition is part of how faith is formed. A person who sits with a shared reading each Sunday morning is taking part in the same kind of practice.
Finally, the honest warning in this chapter encourages self-examination without despair. Someone who notices a recurring pattern of drifting from a good commitment can take the chapter’s example seriously, remembering that God knows our tendencies and still offers steadfast presence. The song Moses teaches is a reminder that God’s truth can be carried in memory and worship even when feelings and circumstances grow unstable.
Questions for Reflection
- How does Moses’ confidence in God’s presence shape the way he speaks to Joshua and the people?
- Why do you think God chose to give Israel a song as well as a written law?
- What does it mean that the law was to be read to children and foreigners as well as adults?
- Where in your own life have you needed to hand responsibility to someone else, and what did it reveal about trust?
A Prayer From Deuteronomy 31
Lord, you are the one who goes before us and who does not fail or forsake us. When the work we have given our lives to must pass into other hands, help us to release it with honesty and trust. Teach us to remember your words and to keep them alive in our households, so that those who come after us may know you. Keep our hearts from turning aside to lesser things, and remind us of your faithfulness when we are tempted to forget. Amen.
