Unpacking Joshua 6:17-19: The Holy Ban

Setting the Stage: Jericho and the Promise of Rahab

This moment in Joshua 6 comes right after the Israelites have marched around Jericho for seven days, following God’s unusual instructions, all stemming from the earlier mission of two spies who entered the city and were hidden by Rahab.

Back in Joshua 2:1-21, those spies were sent to scout Jericho and ended up in the home of Rahab, a woman who chose to protect them even though she lived in an enemy city. She told them, 'I know that the Lord has given you the land... for the Lord your God, he is God in heaven above and on the earth beneath' (Joshua 2:9, 11), showing her faith. In return for her help, the spies promised to spare her and her family when Israel attacked - this is why she is now the only exception in a city otherwise devoted to total destruction.

The command to completely destroy Jericho - called 'ḥerem' - wasn’t about cruelty but about setting apart something entirely for God in a holy war, showing that Israel’s victory came from Him and wasn’t for personal gain.

The Devotion of Jericho: A Turning Point in God's Plan

The destruction of Jericho marked a military victory and a sacred act of obedience that fulfilled God’s earlier commands and revealed a deeper pattern of judgment and salvation.

This was not an ordinary battle order. It was a divine act of consecration, giving everything in Jericho wholly to God through destruction, as Deuteronomy 7:1‑6 commands: 'You shall devote them to complete destruction... You shall make no covenant with them and show no mercy to them.' The same instruction is repeated in Deuteronomy 20:16-18, warning that sparing the nations would lead Israel into idolatry and corruption. By placing Jericho under ḥerem, God was making a clean break with the past and setting apart Israel as a holy people. Rahab’s rescue, then, stands in powerful contrast - she, a Canaanite outsider, is spared not because of nationality but because of faith, showing that God’s judgment falls on rebellion, not ethnicity.

The word 'ḥerem' itself carries weight - it means something utterly set apart, either for destruction or for God’s exclusive use. The city was cursed, but the metals - silver, gold, bronze, and iron - were not destroyed. They were purified and brought into the Lord’s treasury, symbolizing how something once corrupt can be redeemed for holy use. God does not only remove evil. He repurposes what can be made clean. Rahab, once part of a doomed city, becomes part of Israel’s story - eventually listed in the lineage of Jesus - showing that even in judgment, God makes a way for salvation.

The warning against taking devoted things was about trust, not merely about rules. To steal from the ḥerem was to act as if the victory depended on human strength or deserved spoils, rather than God’s power. It was a test of whether Israel would walk in faith or fall into greed.

This moment sets the tone for what’s ahead: obedience brings life, but hidden sin brings public consequences - a truth that will soon unfold in the story of Achan.

Holy War and Mercy: Wrestling with a Difficult Story

This passage forces us to grapple with hard questions about God’s judgment and the idea of holy war - how can a loving God command the destruction of a whole city?

The Canaanite nations were deeply entrenched in child sacrifice and idolatry, corrupting morality and faith. God’s command to remove them was not merely punishment; it was a way to protect Israel’s spiritual future. Still, the story isn’t about blanket condemnation - Rahab’s rescue shows that God always makes room for those who turn to Him, no matter their past.

Today, we do not view this as a model for violence but as a picture of total surrender. Just as Israel gave everything to God, we are called to let go of anything that competes with our loyalty to Him. The metals spared from destruction and placed in God’s treasury illustrate a greater truth: God can take what was once broken and use it for good, as He did with Rahab. And later, in 2 Corinthians 4:6, Paul writes, 'For God, who said, 'Let light shine out of darkness,' has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ' - showing that God’s ultimate victory isn’t through destruction, but through bringing light into darkness and transforming lives from the inside out.

Rahab, the Devoted City, and the Gospel: A Story That Points to Jesus

Rahab’s rescue from a doomed city and the total destruction of Jericho are not merely ancient history; they are part of a larger story that points to Jesus and the final judgment.

Rahab, a foreigner and a sinner by society’s standards, is not only spared but honored - she’s named in Matthew 1:5 as one of the ancestors of Jesus, included in the family line of the Messiah. Hebrews 11:31 praises her faith: 'By faith Rahab the prostitute did not perish with those who were disobedient, because she had given a friendly welcome to the spies.' James 2:25 confirms that her actions proved her faith was real: 'Was not also Rahab the prostitute justified by works when she received the messengers and sent them out by another way?' Her story shows that salvation has always been by faith, not by being good enough or belonging to the right group.

The complete destruction of Jericho under the ḥerem is a foreshadowing of God’s final judgment on all evil. Nothing devoted to destruction could be kept without bringing guilt on the whole camp; likewise, Revelation 17‑18 describes the fall of Babylon - a symbol of human rebellion and corruption - that must be completely undone. In Revelation 18:2, an angel calls out, 'Fallen, fallen is Babylon the great! She has become a dwelling place for demons...' This echoes Jericho’s fate, showing that God will one day clear away all that opposes Him. Yet even there is hope: Rahab and her family were pulled out of a doomed city, and the gospel offers rescue to anyone who turns to Jesus before the final day.

The metals taken from Jericho and brought into God’s treasury - silver, gold, bronze, and iron - hint at how God redeems what was once lost. Rahab, once part of a cursed city, becomes part of Christ’s lineage. This shows that no one is beyond saving, and God can use even the most broken stories for His glory. The same power that spared Rahab and judged Jericho is at work today, calling people out of darkness and into His light.

This pattern - judgment on sin, mercy for the faithful, and the transformation of what was once lost - prepares us for the cross, where Jesus bears the judgment we deserved and opens the door for sinners like Rahab, and like us, to be made new.
