Deuteronomy 31 is the chapter where Moses hands leadership to Joshua, gives Israel a written law to be read aloud, and warns the people about the failure that lies ahead. Readers come to it looking for a clear picture of how Moses’ final act fits into the story of Israel, and for encouragement that God goes ahead of His people into what they cannot yet see. The chapter is short, but it holds together a farewell, a commission, and a sobering forecast.
Deuteronomy 31 Summary
The chapter opens with Moses telling all Israel that he is 120 years old and can no longer lead them across the Jordan. He assures the people that the LORD Himself will go before them and drive out the nations in the land, and that Joshua will lead them, just as the LORD has said. Moses then calls Joshua in front of the whole nation and charges him to be strong and courageous.
From there the focus shifts to the written law. Moses hands it to the priests and elders, and commands that it be read publicly every seven years at the Feast of Booths so that every generation, including the children and the foreigners living among them, will hear it and learn to fear the LORD. The chapter then moves to the Tent of Meeting, where the LORD appears in a pillar of cloud, commissions Joshua, and tells Moses that Israel will turn away after his death. The LORD commands Moses to write a song as a witness against the coming unfaithfulness, and Moses teaches it to the people. The chapter closes with Moses placing the book of the law beside the ark and speaking the song in the hearing of all the assembly.
Background and Setting
Deuteronomy is traditionally attributed to Moses, who speaks these words to Israel on the plains of Moab just before they enter Canaan. Most scholars recognize that the book took its present shape over a longer period and may have been edited later, but the chapter presents itself as Moses’ final address and treats the setting as the eve of the conquest. Chapter 31 sits near the end of Moses’ three long speeches, and it serves as a hinge between his teaching and Israel’s future under Joshua.
The audience is the whole generation of Israelites who came out of Egypt’s slavery, now grown and standing on the edge of the promised land. The chapter also looks ahead to later generations who will need the law read to them and will need a song to remind them of their history. That is why the instructions about public reading and the teaching of the song carry so much weight within the chapter.
Deuteronomy 31 Section by Section
Verses 1-8: The Leader Who Goes Before You
Be strong and courageous. Don’t be afraid or scared of them; for the LORD your God himself is who goes with you. He will not fail you nor forsake you.”
Deuteronomy 31:6 (WEB)
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 31:8 (WEB)
Moses begins by admitting his limits. He is 120 years old and cannot go on leading, and he has been told he will not cross the Jordan. Rather than leaving the people with his own strength as their anchor, he points them to the LORD, who will go over before them and destroy the nations in their path. The repeated call to courage is not a pep talk built on confidence in human ability. It rests on a simple claim: the God who brought them out of Egypt is the one walking into Canaan with them.
Moses then turns to Joshua in the sight of all Israel and gives him the same charge. The public commissioning matters because it tells the people that the transition is God’s plan and not a private arrangement. Israel is not being left alone. They are being led, and the promise of God’s presence is repeated so that no one hears only Joshua’s name and misses the Lord behind it.
Verses 9-13: The Law Read Aloud to Every Generation
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 31:12 (WEB)
Moses writes the law and entrusts it to the priests and elders, the people responsible for carrying it forward. Every seven years, at the Feast of Booths, the whole nation is to gather and hear it read. Men, women, children, and foreigners living among them are all included, because the goal is that everyone would learn to fear the LORD and keep His words.
The instruction shows how seriously the law was meant to shape ordinary life. Hearing it was not a private act of study but a shared experience that bound families and communities to the same covenant. Even the children who had not yet known the law are named, which means the responsibility to teach it reaches forward into every future household.
Verses 14-18: A Sobering Forecast in the Tent of Meeting
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.
Deuteronomy 31:16 (WEB)
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 31:17 (WEB)
In the Tent of Meeting the LORD appears in a pillar of cloud and speaks to Moses directly. He commissions Joshua there, but He also delivers an honest prediction: after Moses dies, Israel will turn to the gods of the land and break the covenant. The LORD describes the consequences plainly, including His own hiding of His face and the trouble that will follow. This is not a surprise to God, and the chapter does not soften it.
The passage is hard to read, yet it displays something important about God’s character. He tells the truth about human unfaithfulness before it happens, and He gives the people a way to remember what He said. The warning is given so that when disaster comes, the people will understand its cause and know that the covenant God made with them was still true.
Verses 19-22: The Song as a Witness
“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.
Deuteronomy 31:19 (WEB)
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 31:21 (WEB)
The LORD commands Moses to write a song and teach it to the people so that it will be in their mouths. The song will testify against them when they fall into trouble, because it will be remembered by their descendants. Moses writes it the same day and teaches it to the nation. Memory set to melody is hard to forget, and the song is designed to outlast the moment of failure.
The detail reveals how God works through the ordinary practices of a community. A song is sung at gatherings, carried in the memory of children, and recalled in hard seasons. God uses it to keep His people honest about their own history, and to show that He knew the path they would take long before they walked it.
Verses 23-30: The Book Placed Beside the Ark
“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.
Deuteronomy 31:26 (WEB)
For I know that after my death you will utterly corrupt yourselves, and turn away from the way which I have commanded you; and evil will happen to you in the latter days; because you will do that which is evil in the LORD’s sight, to provoke him to anger through the work of your hands.”
Deuteronomy 31:29 (WEB)
Moses finishes writing the law in a book and commands the Levites to place it beside the ark of the covenant. It is to stand as a witness against the people, a standing reminder of what God required. Moses knows the people’s rebellion well, and he speaks plainly about their stiff necks. He calls the elders and officers together so he can speak these words in their hearing and call heaven and earth to witness.
The chapter ends with Moses speaking the song to the whole assembly until it is complete. The sequence leaves the reader with a clear picture: the law is written, placed in the sacred space, read to the people, and sung into their memory. Whatever failure lies ahead, the means of return has already been put in their hands.
Key Themes in Deuteronomy 31
- God’s going before His people: Repeated across the chapter, the LORD goes ahead of Israel and drives out their enemies.
- Courage grounded in presence: The call to be strong rests on God’s promise to be with His people, not on their own resources.
- Succession and continuity: Moses hands leadership to Joshua in a public and divinely directed transition.
- The written word as witness: The law and the song are placed where they can testify to the people and to future generations.
- Honest knowledge of human failure: God and Moses name the coming unfaithfulness plainly, so the people will not be unprepared.
Lessons From Deuteronomy 31 for Today
Many people today face a transition they did not choose: a new job, a new role at church, a parent who can no longer care for the family as before. Deuteronomy 31 shows that the one who goes before us is not limited to the person we are handing over from. Moses’ departure did not leave Israel without God, and a change in leadership at work or in the home does not mean the presence of the Lord has changed.
The chapter also speaks to parents and teachers who worry about passing faith to the next generation. Israel was told to read the law aloud and to teach the song so that children who had not yet known it would learn to fear the LORD. Regular, shared practices like reading Scripture at family meals, singing hymns together, or talking about God’s faithfulness in ordinary days are the modern equivalents of the Feast of Booths.

- What practices in your household or small group help the next generation hear and remember God’s word?
- When you think about the honest warnings in this chapter, how do they shape your trust in God’s faithfulness?
A Prayer From Deuteronomy 31
Lord, you go before me into every place I have not yet seen. When I feel my own weakness, remind me that your presence is enough for what you have called me to do. Help me to be strong and courageous because you will not fail me or forsake me. Give me a love for your word that I can pass on to the people who come after me, so they will know who you are and fear you with a clean heart. Keep me honest about my own failures, and draw me back to you when I wander. Thank you for staying faithful even when I do not. Amen.
