Jesus: From Genesis to Revelation

Day 1: Be Strong and Courageous -- Joshua Commissioned

Reading

Historical Context

The book of Joshua opens with one of the starkest transitions in all of Scripture: “After the death of Moses the servant of the LORD” (Joshua 1:1). The Hebrew acharey mot Mosheh carries the weight of finality. Moses – the man who confronted Pharaoh, parted the sea, received the Torah on Sinai, interceded for a rebellious nation for forty years – is dead. Deuteronomy 34 tells us that God himself buried Moses in an unmarked grave in the valley of Moab, and that “no one knows the place of his burial to this day” (Deuteronomy 34:6). Israel mourned for thirty days. And now a new word comes – not to Moses but to Joshua son of Nun.

Joshua’s credentials were real but modest beside his predecessor’s. He had been Moses’ mesharet – his minister or attendant – since his youth (Numbers 11:28). He had led the army against Amalek at Rephidim (Exodus 17:8-13). He was one of the two faithful spies who returned from Canaan with a report of faith rather than fear (Numbers 14:6-9). Moses had laid hands on him and commissioned him publicly (Numbers 27:18-23; Deuteronomy 31:7-8). But none of this changes the fact that Joshua is being asked to succeed the most towering figure in Israel’s memory. The weight of the moment explains the repetition that follows.

God’s charge to Joshua in this chapter is structured around a threefold repetition of chazak ve’emats – “be strong and courageous” (Joshua 1:6, 7, 9). In ancient Near Eastern commissioning texts, a new ruler or military leader was typically charged by the departing authority with strength and faithfulness. Hittite suzerainty treaties contain similar formulae. But what distinguishes this commission is its ground: the courage is not rooted in Joshua’s military training, political skill, or popular support. It is rooted in a promise – “the LORD your God is with you wherever you go” (Joshua 1:9). The Hebrew immekha (“with you”) is the same language God used with Abraham, Isaac, Jacob, and Moses. The presence that sustained the patriarchs and the lawgiver is now pledged to the general.

The middle charge (Joshua 1:7) introduces a distinctive condition: “Only be strong and very courageous, being careful to do according to all the law that Moses my servant commanded you.” The addition of me’od (“very”) intensifies the demand, and the object of the courage shifts from military conquest to Torah obedience. Joshua is to meditate on the sefer hattorah (“the Book of the Law”) day and night. The Hebrew hagah (“meditate”) means to murmur, to speak under one’s breath – it describes an active, oral engagement with the text, not silent reflection. The word appears again in Psalm 1:2, where the righteous person meditates on the Torah continually. Military success, God is saying, depends on scriptural faithfulness. The sword follows the scroll.

The people’s response in Joshua 1:16-18 mirrors God’s own language. They pledge obedience to Joshua “just as we obeyed Moses in all things” – an ironic claim, given what “obeying Moses” looked like for the previous generation. But their final word is striking: “Only be strong and courageous” (Joshua 1:18). The people return God’s own charge to their leader. The chapter ends with the entire community speaking the language of divine commission. The vocabulary of courage has become communal.

Christ in This Day

The name Joshua – Yehoshua in Hebrew – means “the LORD saves.” It is the same name that the angel will give to Mary’s son: “You shall call his name Jesus (Iesous, the Greek form of Yehoshua), for he will save his people from their sins” (Matthew 1:21). The linguistic identity is not coincidental. The author of Hebrews builds an entire argument on it: “For if Joshua had given them rest, God would not have spoken of another day later on. So then, there remains a Sabbath rest for the people of God” (Hebrews 4:8-9). The Greek text uses Iesous for both Joshua and Jesus, and the reader must discern from context which is meant. The point is that they are meant to blur together. Joshua is a type – a living preview – of the greater deliverer whose name he carries. He leads Israel into the land; Jesus leads God’s people into eternal rest. He conquers Canaan; Jesus conquers death. He is commissioned by God to complete what Moses could not finish; Jesus fulfills the law that Moses delivered but no one could keep.

The threefold charge – “be strong and courageous” – resonates with the assurance Christ gives his own disciples at the end of Matthew’s Gospel. “All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations… And behold, I am with you always, to the end of the age” (Matthew 28:18-20). The structure is identical: a declaration of authority, a command to go, and a promise of presence. Joshua was told, “the LORD your God is with you wherever you go.” The disciples were told, “I am with you always.” The promise that sustained Israel’s general at the Jordan sustains Christ’s church to the ends of the earth. And the author of Hebrews clinches the connection: “He has said, ‘I will never leave you nor forsake you.’ So we can confidently say, ‘The Lord is my helper; I will not fear; what can man do to me?’” (Hebrews 13:5-6). The promise of divine presence given to Joshua is now the inheritance of every believer – not because we are generals leading armies but because we are united to the one whose name means “the LORD saves.”

The fact that God commissions Joshua only after Moses’ death carries its own Christological weight. The old covenant leader has died. The new leader bears the name “the LORD saves.” The pattern is the same one Paul traces in Romans and Galatians: the law came through Moses, but it could not bring the people into rest. It took a Joshua – a Jesus – to lead them across the boundary and into the promise. Moses brought Israel to the edge. Joshua brought them in. The law brings us to the end of ourselves. Christ brings us home.

Key Themes

Connections

Old Testament Roots

God’s charge to Joshua echoes the charge Moses gave him publicly in Deuteronomy 31:7-8: “Be strong and courageous, for you shall go with this people into the land… It is the LORD who goes before you. He will be with you; he will not leave you or forsake you. Do not fear or be dismayed.” The promise of divine presence reaches back further still – to Jacob at Bethel (“Behold, I am with you,” Genesis 28:15), to Moses at the burning bush (“I will be with you,” Exodus 3:12), and forward to Jeremiah (“Do not be afraid of them, for I am with you to deliver you,” Jeremiah 1:8). The commissioning language is covenantal shorthand: God pledges his presence to those he sends.

New Testament Echoes

Hebrews 4:8-11 uses Joshua’s story to argue for a greater rest that Joshua could not provide. Matthew 28:18-20 echoes the commission structure – authority, command, promised presence. Hebrews 13:5-6 applies the Deuteronomy/Joshua promise of presence directly to the church: “I will never leave you nor forsake you.” Paul’s exhortation in 1 Corinthians 16:13 – “Be watchful, stand firm in the faith, act like men, be strong” – carries the same verbal energy as the charge to Joshua, now directed to believers in Corinth.

Parallel Passages

Deuteronomy 31:1-8 records Moses’ public commission of Joshua. Numbers 27:18-23 describes the laying on of hands and the transfer of authority. Psalm 1:1-3 develops the theme of Torah meditation, using the same root hagah and the same promise of prosperity. Isaiah 41:10 extends the promise of presence and courage to exilic Israel: “Fear not, for I am with you; be not dismayed, for I am your God.”

Reflection Questions

  1. God commands courage three times in nine verses, each time grounding the command in his own presence. Where in your life do you need to hear the distinction between courage as a feeling you must generate and courage as an obedience you can practice because God is present?

  2. Joshua 1:8 places Torah meditation at the center of the commission – not as a devotional add-on but as the primary means of success. What would it look like to treat engagement with Scripture not as one spiritual discipline among many but as the foundation on which every other form of faithfulness is built?

  3. The people’s response to Joshua echoes God’s own words back to their leader: “Only be strong and courageous” (Joshua 1:18). How does a community that speaks the language of divine commission to one another create an environment where obedience becomes possible?

Prayer

Lord God, you spoke to Joshua at the edge of the Jordan and commanded him to be strong and courageous – not because the task ahead was small but because your presence was sure. We confess that we often treat courage as a feeling we must manufacture rather than an obedience we can practice. We have trusted our own strategies more than your word, our own strength more than your presence. Teach us, as you taught Joshua, that faithfulness begins with the murmuring of your word in the dark – that the scroll precedes the sword, that meditation on your truth is the ground of every advance. Thank you that the promise given to Joshua is now given to us in Christ, who said, “I am with you always, to the end of the age.” Make us strong and courageous – not in ourselves but in the unshakeable presence of the one whose name means “the LORD saves.” Amen.
