Deuteronomy 31:23

Deuteronomy 31:23, in plain English

God then turns to Joshua and gives him the same charge He gave to Moses: lead the people into the promised land, and trust that God will be with you.

Why it's here

Joshua is standing there listening, probably feeling the weight of what's about to fall on his shoulders. He's brave and faithful, but he's about to lose the man who's guided Israel for forty years. God's words to him are both a promotion and a comfort. Notice that God doesn't give Joshua a detailed strategic plan—He gives him a promise. 'I will be with you' is everything Joshua needs to know.

Who's speaking

God is speaking directly to Joshua, commissioning him as Moses's successor.

Where it sits in the story

This shows how God works through transitions. Moses was faithful, but he's not irreplaceable. God has already prepared someone else, and His presence and faithfulness don't depend on any one person. Joshua is part of a chain of leaders that stretches through Scripture—each one stepping into their calling knowing God goes with them.

The scholarly reading

God explicitly commissions Joshua as Moses' successor, commanding him to lead Israel into Canaan with the assurance of divine presence and support.

Language and setting

Joshua's commissioning occurs at the precise moment of institutional transition—Moses is departing, and Joshua must assume leadership. The language "Be strong and courageous" (חזק ואמץ, chazaq ve-ametz) appears repeatedly in Joshua's commissioning (Joshua 1:6-7, 9, 18), establishing a theological rubric for faithful leadership under pressure. God's self-commitment ("I will be with you") echoes the promise to Abraham and the patriarchs, and will recur to David and the prophets. Theologically, this represents what Gerhard von Rad identified as the divine assurance that undergirds Israel's historical experience—not fortune or military superiority, but covenantal fidelity.

Significance

Joshua becomes the vehicle through which God accomplishes the conquest narrative, yet the commissioning immediately precedes Moses' rehearsal of covenant judgment (vv. 28-30), creating narrative tension: Joshua receives authority while the community receives prophetic warning. This foreshadows the polarities of Joshua's book—victory and failure, depending on Israel's obedience.

21And when many troubles and afflictions have come upon them, this song will testify against them, because it will not be forgotten from the lips of their descendants. For I know their inclination, even before I bring them into the land that I swore to give them.”

22So that very day Moses wrote down this song and taught it to the Israelites.

23Then the LORD commissioned Joshua son of Nun and said, “Be strong and courageous, for you will bring the Israelites into the land that I swore to give them, and I will be with you.”

24When Moses had finished writing in a book the words of this law from beginning to end,

25he gave this command to the Levites who carried the ark of the covenant of the LORD:

Read all of Deuteronomy 31 — Moses commissions Joshua and writes the law in a book. He knows they'll rebel — and writes a song to remind them why.
