Introduction

In 2 Samuel 20 we hear two calls: a trumpet of defiance that scatters the flock, and a trumpet of wisdom that brings them home. Perhaps you have come today feeling scattered by pressure at home, insecurity at work, and friendships worn thin. This text was given for such days. It traces the lines of our fractures, shows the seams of repair, and directs us to the King chosen by God, unshaken when everything around us quakes. With that path in mind, let us listen first to how division begins.

I. How Division Scatters

In verses 1 and 2 we read, “Now there happened to be there a worthless man, whose name was Sheba, the son of Bichri, a Benjaminite, and he blew the trumpet and said, ‘We have no portion in David, and we have no inheritance in the son of Jesse; every man to his tents, O Israel!’ So all the men of Israel withdrew from David and followed Sheba the son of Bichri. But the men of Judah followed their king steadfastly from the Jordan to Jerusalem” (2 Samuel 20:1–2, ESV).

Do you hear how quickly the temperature rises. Scripture does not mince words. Sheba lifts a trumpet and sends a tired people running to their tents. The words sound like freedom, but they fracture a nation. He steals covenant vocabulary like portion and inheritance and fills it with resentment. The temperature rises quickly when pride is in charge.

Division often begins with a voice that names your grievance. It whispers that distance is safer than loyalty and that breaking away will finally bring belonging. Old rivalries sit like dry kindling. One spark and the brushfire runs. Trust that took years to build can be torn down in an afternoon.So the ten tribes drift after Sheba, while Judah keeps a grip on her king.

Here is the first lesson, and it is plain. God does not smile on those who sow discord. “A worthless person, a wicked man, goes about with crooked speech” (Proverbs 6:12, ESV). “A dishonest man spreads strife, and a whisperer separates close friends” (Proverbs 16:28, ESV). Our Lord prayed for a different story. “That they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me” (John 17:21, ESV).

Now notice the contrast between this false king and our true King. Sheba cries, “We have no portion in David,” but Jesus answers with every portion. “Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places. In him we have obtained an inheritance” (Ephesians 1:3, 11, ESV). So we sing with David, “The LORD is my chosen portion and my cup” (Psalm 16:5, ESV).

Hear me when I say this, our unity does not come from our similariteis to one another. It comes from our being united in Christ. “For he himself is our peace, who has made us both one and has broken down in his flesh the dividing wall of hostility” (Ephesians 2:14, ESV).

Here is how this meets us. When conflict rises with a brother or sister, pause and ask two questions. What did Jesus purchase with his blood in this person. What did Jesus purchase with his blood in this church. Let his cross bridle your anger. Let his empty tomb lengthen your patience. Take the first step toward peace, because he first stepped from heaven to Calvary for you. Sin scatters, and Christ gathers. The kingdom shakes, but the King does not.

With the problem of scattering before us, the text now turns to show how wisdom begins to heal what pride has torn. Watch how the scene shifts from the trumpet of revolt to the quiet work of mercy.

II. How Wisdom Saves a City

Lets look at verse 3. The king returned to Jerusalem. “And David came to his house at Jerusalem. And the king took the ten concubines whom he had left to care for the house and put them in a house under guard and provided for them, but did not go in to them. So they were shut up until the day of their death, living as if in widowhood” (2 Samuel 20:3, ESV). If you remember our sermon last week, Absalom had sinned against these women in the open. David cannot unwind the clock and undo what has happened to these women, but he can build a shelter for them. He cannot erase the shame, but he can surround them with care. Royal power bends itself to merciful provision.

This is easy to miss, yet it is exactly where wisdom starts. When conflicts blaze, go find the ones who were burned. Firefighters do not begin with the structure. They begin with the people inside. In the same way, when a relational fire has scorched hearts and hopes, godly wisdom seeks out those who have been harmed and tends to them. David could not undo what had been done, but he could create a place of shelter and provision for those caught in the crossfire. After the flames die down, we are invited to go back for the bruised and the forgotten, to gather them up in mercy and restore them with compassion.

Lest we forget, this is the kingly attitude that Jesus takes toward us. Our Shepherd does not stride past bruises. “He will tend his flock like a shepherd; he will gather the lambs in his arms” (Isaiah 40:11, ESV). “A bruised reed he will not break, and a faintly burning wick he will not quench” (Isaiah 42:3, ESV). Taking time to show mercy and compassion to the vulnerable is not a delay of duty. It is the first duty of kings and Christians.

The narrative then quickens. Mercy is followed by movement. After showing care, David gives orders. He instructs Amasa, whom he had appointed to replace Joab as commander, to muster the men of Judah within three days so they can pursue Sheba’s rebellion. Amasa, however, fails to appear at the appointed time. His delay allows the revolt to grow stronger and leaves David’s forces unprepared. To regain momentum, David sends Abishai with the king’s guard, and Joab tags along. When they meet Amasa at Gibeon, Joab steps forward as if to greet his cousin. He takes Amasa by the beard with his right hand in a gesture of kinship and kisses him, but with his left he draws a hidden dagger and kills him. After eliminating his rival, Joab shouts to the soldiers, “Whoever is for Joab and for David, follow Joab” (2 Samuel 20:11, ESV), subtly placing his own name before the king’s to assert control while claiming loyalty.

So what do we learn from this turn in the road. First, procrastinating on duty is harmful. Amasa’s hesitation shows how a leader’s unwillingness to act promptly can endanger everyone. When a command from God or from a rightful authority is left on the shelf, it begins to decay. In times of crisis, delayed obedience allows rebellion and resentment to fester and becomes disobedience hiding under a cloak of caution. We should respond quickly to what is right rather than rationalize our delay.

Second, passion without submission is rebellion. Joab’s military skill and zeal were unmatched, but he repeatedly placed his own agenda above the king’s orders. He thought that victory on the battlefield justified any method. He confused personal success with righteousness and his own speed with God’s timing. In this incident he murdered Amasa to secure his position and then called others to follow him as if he were synonymous with David. Scripture warns that “the anger of man does not produce the righteousness of God” (James 1:20, ESV). Those of us entrusted with influence must place our gifts under God’s authority. Zeal must be tempered by obedience. Do not baptize manipulation or violence as strategy. Obey promptly, speak truthfully, act courageously, and repent quickly when you stray.

With Joab now in command again, the chase reaches its climax. After Amasa’s death, Sheba flees northward. He gathers discontented men and runs toward the fortified town of Abel of Beth-maacah near Israel’s northern frontier. Joab pursues and lays siege to the city, piling up a ramp against the wall and battering the gates with rams. Inside the city, a wise woman stands on the ramparts and calls out to negotiate with Joab. She reminds him that Abel has long been a place where people seek wisdom and settle disputes and asks why he would destroy a city loyal to Israel and to the Lord. Joab explains that he only wants the traitor Sheba. The woman replies that his head will be thrown over the wall. It is a grim solution, yet it spares a city.

Listen to how the chapter brings this full circle. The rebellion that began with a trumpet of defiance now ends with a trumpet of peace. “And he blew the trumpet, and they dispersed from the city, every man to his home. And Joab returned to Jerusalem to the king” (2 Samuel 20:22, ESV).

Here the text opens a door to the gospel. In David’s kingdom, Abel’s citizens preserved themselves by cutting off the head of the rebel. Justice was satisfied through the removal of one guilty man. The gospel announces a different deliverance. In Christ’s kingdom, the King himself takes the place of the traitors. Not countless innocents spared by the death of one guilty man, but one innocent man who dies so that countless guilty traitors can be spared. “For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life” (Romans 5:10, ESV). At the cross, Jesus makes peace not by demanding our blood but by shedding his own. He is “making peace by the blood of his cross” (Colossians 1:20, ESV). The sword of judgment falls not on sinners but on the sinless King, so that those who deserved death could become children of God.

And the story keeps us looking ahead. Like this lesser rebellion, the greater rebellion of sin and death will end with a trumpet as well. “Then will appear in heaven the sign of the Son of Man, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory. And he will send out his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of heaven to the other” (Matthew 24:30–31, ESV). The scattering will end for good.

Having seen how wisdom saves a city, the chapter gives us one more picture. It is quieter, but it matters just as much. Wisdom must be followed by steadiness.

III. How Faithfulness Steadies a People

The chapter closes with a list of names. It feels a little anticlimactic, but it is a reminder that a shaken kingdom needs order. “Now Joab was in command of all the army of Israel; and Benaiah the son of Jehoiada was in command of the Cherethites and the Pelethites; and Adoram was in charge of the forced labor; and Jehoshaphat the son of Ahilud was the recorder; and Sheva was secretary; and Zadok and Abiathar were priests; and Ira the Jairite was also David’s priest” (2 Samuel 20:23–26, ESV). After the trumpet of emergency comes the quiet of good arrangement. Governance is not busywork. It is the scaffolding that lets worship, justice, and mercy go on.

The Spirit does the same in Christ’s body. “But as it is, God arranged the members in the body, each one of them, as he chose” (1 Corinthians 12:18, ESV). The risen Lord “gave the apostles, the prophets, the evangelists, the shepherds and teachers, to equip the saints for the work of ministry, for building up the body of Christ” (Ephesians 4:11–12, ESV). Good order is good stewardship that serves human flourishing.

Most on that list never wrote a psalm or preached a sermon. Yet their steady hands helped to stabalize the kingdom. Take courage, obscure saint. Your service may be small. Your name may be missing from the program. The King sees. “Whatever you do, work heartily, as for the Lord and not for men” (Colossians 3:23, ESV). Esteem those who labor among you. Be at peace among yourselves. In your place, be faithful.

Conclusion

Now let us gather what we have learned and bring it all together. Everything we have read looks forward to a better King and to an unshakable kingdom. David’s palace trembles. Zion above does not. As Scripture declares, “You have come to Mount Zion and to the city of the living God, the heavenly Jerusalem” and “to Jesus, the mediator of a new covenant” (Hebrews 12:22, 24, ESV). Sheba shouted, “No portion in David.” The gospel shouts, “Every spiritual blessing in Christ” (Ephesians 1:3, ESV). Joab saved a city by taking a head. Jesus saves the world by bowing his own head. “For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God” (2 Corinthians 5:21, ESV).

So here is our response. Promote unity. Refuse the whispers that separate close friends. Protect the weak. Move toward the harmed. Serve faithfully where God has placed you. Sin scatters, and Christ gathers. The kingdom is shaken, but the King is not.
