Companion: Deep Study
A condensed companion to the full study. For each section of the expanded outline: key insights, applications, and the application questions for discussion.
Section 1 — Faithful Soldiers Sent Home with Blessing and Charge (Joshua 22:1–9)
Key Insights
- Joshua honors the eastern tribes because they did not forsake their brothers “these many days, down to this day” (v. 3).
- The release rests on God’s faithfulness, for “the LORD your God has given rest to your brothers, as he promised them” (v. 4).
- Joshua’s charge puts love first and joins it to walking, keeping, clinging (Hebrew dabaq) and serving (v. 5).
- The warriors go home blessed and are told to share the spoil with those who guarded their homes (v. 8).
- Christ, the greater Joshua, finished the work the Father gave Him and now shares the spoils of His victory with His people (Ephesians 4:8).
Applications
- Finish the commitments you make to Christ’s people, even when they cost you (Psalm 15:4).
- Let obedience flow from love, because “We love because he first loved us” (1 John 4:19).
- Share God’s blessings generously with those who serve quietly behind the front line (1 Samuel 30:24).
Application Questions
- Is there a commitment you made to brothers and sisters in Christ that you have quietly abandoned before the work was finished?
- Does your obedience to God flow from love for Him, or has it become merely habit or duty?
Section 2 — An Altar of Imposing Size and a Nation Roused (Joshua 22:10–12)
Key Insights
- The eastern tribes build “an altar by the Jordan, an altar of imposing size” (v. 10), a monument meant to be seen.
- Their motive was right, but they acted without consulting Joshua, the high priest or their brothers.
- Israel hears a report and gathers at Shiloh “to make war against them” (v. 12), zealous for the one altar the law required.
- Interpreters differ on whether the altar stood on the western or eastern bank, and the meaning does not depend on the answer.
- Christ fulfills Israel’s zeal for God’s house and is Himself the one way to the Father (John 14:6).
Applications
- Care about how God is worshiped, and let your zeal be for the one Mediator rather than for preferences.
- Seek counsel and explain yourself before doing something others could easily misunderstand (Proverbs 15:22).
- Refuse to act on hearsay, since “The one who states his case first seems right, until the other comes and examines him” (Proverbs 18:17).
- Never use this passage to justify force or coercion in religion, because the church’s weapons are spiritual (2 Corinthians 10:4).
Application Questions
- When you hear a troubling report about another believer or congregation, is your first instinct to gather for battle or to go and inquire?
- Have you ever done something with good intentions but without counsel, in a way others could easily misunderstand?
Section 3 — Phinehas and the Delegation: Breach of Faith, Peor and Achan (Joshua 22:13–20)
Key Insights
- Israel sends Phinehas and ten chiefs to inquire before it fights, as the law required (Deuteronomy 13:14).
- The delegation charges breach of faith (Hebrew maʻal) and rebellion before hearing an answer, the one flaw in its approach.
- Phinehas recalls Peor, “from which even yet we have not cleansed ourselves” (v. 17), and Achan, whose sin brought wrath on all (v. 20).
- The western tribes offer to share their own land rather than see their brothers build a rival altar (v. 19).
- Christ is the greater Priest who bore God’s wrath and whose blood cleanses what Israel could never cleanse (1 John 1:7).
Applications
- Handle hard conversations in person, through mature and trusted people (Matthew 18:15).
- Join rebuke to a costly offer of help, restoring others “in a spirit of gentleness” (Galatians 6:1).
- Remember past sins as warnings, for they “were written down for our instruction” (1 Corinthians 10:11).
Application Questions
- When you must confront a brother or sister, do you come with accusation only, or also with a costly offer of help?
- Do you treat past sins, your own and your church’s, as lessons that guard you today, or as closed chapters you would rather forget?
Section 4 — The Oath of Innocence: The Mighty One, God, the LORD (Joshua 22:21–23)
Key Insights
- The accused tribes answer without retaliation, giving the soft answer that turns away wrath (Proverbs 15:1).
- They open by twice confessing God as the Mighty One, God, the LORD (v. 22), a confession that itself refutes the charge.
- They appeal first to God’s knowledge and then ask that Israel also be satisfied (v. 22).
- They call down God’s judgment on themselves if they intended any sacrifice on the altar (v. 23).
- Christ, the truly innocent One, was the one Man God did not spare, so that sinners might be spared (Romans 8:32).
Applications
- When misjudged, explain calmly and do not return insult for insult (1 Peter 2:23).
- Live before God first, so that your conscience can welcome His scrutiny (2 Corinthians 1:12).
- Use God’s name with reverence and never as a careless figure of speech (Exodus 20:7).
Application Questions
- How do you respond when you are falsely accused or misunderstood: with counterattack, or with a soft answer?
- Do you speak of God and to God with reverence, especially when you call Him to witness what you say?
Section 5 — A Copy, Not a Rival: The Altar as Witness for the Children (Joshua 22:24–29)
Key Insights
- The builders feared that later generations would say, “You have no portion in the LORD” (v. 25).
- The Jordan might become a false boundary of the covenant and cause their children to “cease to worship the LORD” (v. 25).
- The altar was built “not for burnt offering, nor for sacrifice” (v. 26), but as a witness pointing to the altar at Shiloh.
- It was “the copy of the altar of the LORD” (v. 28), a model (Hebrew tabnith) of the pattern Moses received.
- Christ is the true altar to which every copy pointed, and in Him outsiders become members of God’s household (Ephesians 2:19).
Applications
- Build deliberate witnesses of faith for the next generation in your home and church (Deuteronomy 6:7).
- Cross whatever Jordan separates you from the gathered worship of God’s people (Hebrews 10:25).
- Refuse to draw boundaries in the church that Christ has not drawn (Galatians 3:28).
- Do not treat any object or monument as able to preserve faith, since only the Word and Spirit keep a people.
Application Questions
- What are you doing, deliberately and regularly, so that the next generation will not “cease to worship the LORD” (v. 25)?
- Is there a Jordan in your life, whether distance, schedule or habit, that is quietly separating you from the gathered worship of God’s people?
Section 6 — Peace Restored and the Altar Named Witness (Joshua 22:30–34)
Key Insights
- Phinehas and the chiefs hear the answer, and “it was good in their eyes” (v. 30).
- Phinehas reads their faithfulness as proof that “the LORD is in our midst” (v. 31).
- The assembly that gathered for war instead “blessed God” (v. 33).
- The altar is named Witness, “a witness between us that the LORD is God” (v. 34).
- Christ is our peace, who has made His people one and broken down the dividing wall (Ephesians 2:14).
Applications
- Receive a reasonable explanation gladly, because love “believes all things, hopes all things” (1 Corinthians 13:7).
- Give thanks to God whenever a conflict is resolved and a brother is found faithful (Psalm 133:1).
- Pursue peace in the truth, never by overlooking real error (Romans 14:19).
Application Questions
- When someone gives a reasonable explanation for something that offended you, do you receive it gladly, or do you keep looking for fault?
- When a conflict is resolved and a brother or sister is found faithful, do you give thanks to God?
Christ is the one altar and the one peace of His people: He offered the single sacrifice that no copy could replace, and He gathers every tribe, on both sides of every river, into one household that confesses the LORD is God.
