Deuteronomy 31
1 Moses went and spoke these words to all Israel. 2 He said to them, “I am one hundred twenty years old today. I can no more go out and come in. Yahweh has said to me, ‘You shall not go over this Jordan.’ 3 Yahweh 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 Yahweh has spoken. 4 Yahweh will do to them as he did to Sihon and to Og, the kings of the Amorites, and to their land, when he destroyed them. 5 Yahweh will deliver them up before you, and you shall do to them according to all the commandment which I have commanded you. 6 Be strong and courageous. Don’t be afraid, nor be terrified because of them; for Yahweh your God is he who goes with you. He will not fail you nor forsake you.”
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 Yahweh has sworn to their fathers to give them; and you shall cause them to inherit it. 8 Yahweh is he who goes before you. He will be with you. He will not fail you nor forsake you. Don’t be afraid. Neither be dismayed.”
9 Moses wrote this law, and delivered it to the priests the sons of Levi, who bore the ark of Yahweh’s covenant, and to all the elders of Israel. 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 booths, 11 when all Israel has come to appear before Yahweh your God in the place which he shall 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 your foreigner who is within your gates, that they may hear, and that they may learn, and fear Yahweh your God, and observe to do all the words of this law; 13 and that their children, who have not known, may hear, and learn to fear Yahweh your God, as long as you live in the land where you go over the Jordan to possess it.”
14 Yahweh said to Moses, “Behold, your days approach that you must die. Call Joshua, and present yourselves in the Tent of Meeting, that I may commission him.” Moses and Joshua went, and presented themselves in the Tent of Meeting. 15 Yahweh appeared in the Tent in a pillar of cloud; and the pillar of cloud stood over the door of the Tent.
16 Yahweh 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 will be kindled against them in that day, and I will forsake them, and hide my face from them, and they shall be devoured. Many evils and troubles shall come on them, so that they will say in that day, ‘Aren’t these evils come on us because our God is not among us?’ 18 I will surely hide my face in that day for all the evil which they shall have done, in that they have turned to other gods.
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 shall have brought them into the land which I swore to their fathers, flowing with milk and honey, and they shall 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 shall happen, when many evils and troubles have come on them, that this song shall testify before them as a witness; for it shall not be forgotten out of the mouths of their offspring; for I know their ways and what they are doing today, before I have brought them into the land which I swore.”
22 So Moses wrote this song the same day, and taught it the children of Israel. 23 He commissioned Joshua the son of Nun, and said, “Be strong and courageous; for you shall bring the children of Israel into the land which I swore to them; and I will be with you.”
24 It happened, when Moses had finished writing the words of this law in a book, until they were finished, 25 that Moses commanded the Levites, who bore the ark of Yahweh’s covenant, saying, 26 “Take this book of the law, and put it by the side of the ark of Yahweh 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 Yahweh. How much more after my death? 28 Assemble to me all the elders of your tribes, and your officers, that I may speak these words in their ears, and call heaven and earth to witness against them. 29 For I know that after my death you will utterly corrupt yourselves, and turn aside from the way which I have commanded you. Evil will happen to you in the latter days, because you will do that which is evil in Yahweh’s sight, to provoke him to anger through the work of your hands.”
30 Moses spoke in the ears of all the assembly of Israel the words of this song, until they were finished.
Deuteronomy 31 Commentary
Overview
Deuteronomy 31 records the transition from Moses to Joshua while making clear that Israel’s true leader is still Yahweh. Moses is one hundred twenty years old, cannot lead the nation across the Jordan, and must accept God’s earlier judgment that he will not enter the land. Yet the mission does not depend on one human servant. God will go before Israel, Joshua will lead publicly, and the people are called to courage rooted in divine presence rather than confidence in their own strength.
The chapter also protects Israel from losing God’s instruction when its founding generation passes away. Moses writes the law and entrusts it to priests and elders. Every seven years, during the Feast of Booths in the year of release, the law must be read before the entire assembled community—men, women, children, and resident foreigners. Covenant faith is not to survive through vague memory or elite possession of sacred knowledge. Each generation must hear, learn, fear Yahweh, and obey.
A sober tension runs through the second half of the chapter. God commissions Joshua and promises to be with him, yet He also predicts that Israel will become prosperous, turn to other gods, and break the covenant. Moses must therefore write a song, preserved in Deuteronomy 32, to serve as a lasting witness. The written law beside the ark and the song in the people’s mouths will expose future rebellion. Deuteronomy 31 thus joins encouragement with warning: God’s faithfulness secures His purposes, but covenant privilege does not remove human responsibility.
Key Themes
1. God’s work continues beyond one leader. Moses’ ministry is ending, but God’s promise is not. Israel must neither idolize Moses nor imagine that his death cancels its calling. Faithful leaders matter, yet the mission belongs to God, who raises successors and carries His people forward.
2. Courage rests on God’s presence. “Be strong and courageous” is not a command to manufacture fearlessness. Israel and Joshua can face stronger enemies because Yahweh goes with them and before them. Biblical courage acknowledges danger while trusting that God will not abandon His covenant purpose.
3. Leadership succession should be public and orderly. Moses commissions Joshua “in the sight of all Israel.” The people need to know whom God has appointed, and Joshua needs public confirmation of his responsibility. Healthy succession reduces uncertainty and makes clear that leadership is a trust received for the people’s good.
4. Scripture must remain central after charismatic leaders depart. Moses writes the law and places responsibility for its preservation and reading upon established covenant servants. Israel’s future cannot depend on permanent access to Moses’ voice. The written word provides a stable authority by which later leaders and generations can be judged.
5. Public worship includes public instruction. At the Feast of Booths, Israel is not merely to celebrate harvest and remember wilderness provision. The people must hear the law together. Worship that remembers God’s gifts must also renew attention to God’s commands.
6. Covenant teaching includes the whole community. Men, women, children, and foreigners are summoned to hear. The text does not treat theological understanding as the property of a small educated class. Even children who “have not known” must be brought within the hearing of God’s word so that reverence and obedience continue across generations.
7. Prosperity can become a setting for apostasy. God predicts that Israel will eat, become full, and then turn to other gods. Abundance is a gift, but fullness can create forgetfulness and self-sufficiency, as Moses warned in Deuteronomy 8. Spiritual danger does not disappear when hardship ends.
8. God’s foreknowledge does not excuse rebellion. God knows Israel’s future unfaithfulness and even its present inclinations, but the chapter still commands obedience and holds the people accountable. Divine knowledge is not presented as coercion. Israel’s apostasy remains a real covenant betrayal for which the nation is responsible.
9. God provides witnesses against self-deception. The song, the written law, the ark, and even heaven and earth function as witnesses. When judgment comes, Israel will not be able to claim that God’s will was unknown or that the consequences were arbitrary. Revelation makes both repentance and accountability possible.
10. God’s faithfulness includes truthful warning. The chapter’s severe prediction is not opposed to grace. God prepares Israel beforehand, preserves a testimony, and gives future generations words that can interpret their suffering. A loving God does not hide the destructive direction of idolatry.
Important Verses Explained
Deuteronomy 31:2 — “I can no more go out and come in.” The expression commonly refers to active leadership rather than proving that Moses is physically helpless; Deuteronomy 34 later says his natural strength was not abated. His leadership is ending because of age, divine appointment, and God’s declared decision that he will not cross the Jordan.
Deuteronomy 31:3 — God and Joshua go before Israel. The verse places divine and human leadership in proper order. Yahweh Himself goes before the people; Joshua follows as the appointed servant. Israel must respect Joshua without treating him as the ultimate source of victory.
Deuteronomy 31:6 — “He will not fail you nor forsake you.” The promise is spoken to Israel within its covenant mission, then applied personally to Joshua. It does not mean believers will avoid suffering or every apparent setback. It means God will not abandon His people or fail to accomplish what He has truly promised. The wording is later echoed in Hebrews 13 as a foundation for contentment and confidence.
Deuteronomy 31:7–8 — Joshua commissioned before the people. Moses commands Joshua to be courageous because he must lead Israel into its inheritance. Public commissioning honors continuity without pretending Joshua is another Moses in every respect. His confidence must remain in the God who goes ahead of him.
Deuteronomy 31:9 — “Moses wrote this law.” The immediate reference may emphasize the Deuteronomic instruction Moses has just delivered, though the wording participates in the Pentateuch’s broader presentation of Moses as the central mediator and writer of covenant law. The key point here is that the teaching is preserved in durable written form.
Deuteronomy 31:10–11 — Reading in the year of release. Every seventh year, during the Feast of Booths, Israel is to hear the law publicly at the chosen place of worship. This does not imply that Scripture should be ignored during the intervening years. It establishes a recurring national renewal in which the entire covenant community hears its obligations together.
Deuteronomy 31:12–13 — “That they may hear, and that they may learn.” Hearing is meant to produce learning, reverence, and action. Children are included because covenant identity cannot be inherited automatically without instruction. The command reinforces the household teaching already required in Deuteronomy 6.
Deuteronomy 31:14–15 — The pillar of cloud at the Tent. God visibly confirms the transition at the Tent of Meeting. The cloud recalls His presence during the exodus and wilderness journey. Joshua’s commission is therefore not merely Moses’ administrative decision; it is established under divine authority.
Deuteronomy 31:16–18 — “I will hide my face.” Israel will “play the prostitute” by transferring covenant loyalty to other gods. God’s hidden face describes the withdrawal of favorable protection and fellowship under judgment, not divine ignorance or absence from the universe. The people will experience the bitter consequences of rejecting the God whose presence sustained them.
Deuteronomy 31:19–21 — The song as a witness. Songs are memorable and can preserve truth across generations. The coming song will recount God’s faithfulness, Israel’s corruption, and the justice of judgment. When hardship arrives, its familiar words will confront the nation with an interpretation it cannot easily erase.
Deuteronomy 31:23 — “I will be with you.” God personally commissions Joshua with the same courage command Moses gave. Joshua’s task is enormous, but the promise is relational before it is strategic. His deepest security is not military skill, popularity, or Moses’ approval; it is God’s presence.
Deuteronomy 31:26 — The law beside the ark. The book is placed beside the ark, not necessarily inside it with the stone tablets. Its location associates the written covenant with the central sign of God’s kingship and testimony. The law stands as a witness because it clearly states the relationship Israel has accepted.
Deuteronomy 31:27–29 — Moses predicts corruption after his death. Moses is not indulging cynical speculation. Israel’s repeated rebellion during his lifetime gives strong evidence of what may follow, and God has already revealed the outcome. “The latter days” here points broadly to Israel’s future course and resulting calamity, not only to the final period of world history.
Practical Applications
Prepare faithfully for leadership transitions. Good leaders do not cling to roles as though God’s work depends on them. They identify, encourage, and publicly support those who will carry responsibility next, while directing everyone’s confidence toward God rather than personality.
Ground courage in presence, not self-confidence. Fear is not defeated merely by repeating positive statements about yourself. Face responsibility by remembering who God is, what He has commanded, and which promises truly apply to the task before you.
Build communities around repeated hearing of Scripture. One exposure to biblical teaching is not enough for a lifetime. Churches, homes, and study groups should create regular patterns in which the whole community hears, understands, remembers, and practices God’s word.
Include children and newcomers in serious instruction. Do not assume that younger people or those outside established religious circles need only entertainment or simplified slogans. Teach with clarity and patience while inviting them into the shared hearing of Scripture.
Watch your heart when life becomes comfortable. Prosperity can quietly replace dependence with entitlement. Practice gratitude, generosity, worship, and remembrance before abundance becomes a reason to forget the One who provided it.
Receive biblical warnings as an expression of mercy. Hard passages expose paths that destroy worship and community. Rather than dismissing warning as negative, allow it to uncover self-deception and lead to repentance while there is time to respond.
Leave a faithful witness for the next generation. Moses used written teaching and memorable song so truth would outlive him. Consider what habits, words, records, and examples will help others remember God’s faithfulness after your direct influence has ended.
