Why destroy as commanded in Joshua 6:17?
What is the significance of the destruction commanded in Joshua 6:17?

Text of Joshua 6:17

“And the city and all that is in it shall be devoted to the LORD for destruction. Only Rahab the prostitute and everyone with her in her house shall live, because she hid the messengers we sent.”


The Hebrew Concept of Ḥērem (“Devoted to Destruction”)

The key term is ḥērem, a technical covenant word meaning “set apart to YHWH—irreversibly.” In most contexts it denotes complete consecration through destruction (Leviticus 27:28-29; Deuteronomy 7:2). Devoting Jericho in this way was not indiscriminate violence; it was liturgical: the first city conquered in Canaan became a whole-burnt offering, acknowledging that victory belonged solely to the LORD (Joshua 6:16), not to Israel’s military skill.


Historical and Archaeological Backdrop

Jericho occupied a strategic choke point at the Jordan Rift, controlling travel north and south. Carbonized grain jars, fallen mud-brick debris, and a rapid burn layer—unearthed in the 1930s by John Garstang and re-evaluated by Bryant G. Wood (Biblical Archaeology Review, Mar/Apr 1990)—demonstrate a sudden springtime destruction that corresponds strikingly with Joshua 3:15 (harvest-time Jordan flood). Radiocarbon recalibration of charred cereal (Seeds Sample 23-2) yields a 15th-century BC window, harmonizing with the 1406 BC date derived from a conservative reading of 1 Kings 6:1 and Judges chronology. The outer mud-brick wall collapsed outward, forming ramps up the tell—matching the biblical description, “the wall fell flat, and the people went up” (Joshua 6:20). The lone north-facing domestic quarter left standing aligns with excavation Area G, a sector where portions of wall remain to full height; this fits Rahab’s house “on the wall” (Joshua 2:15).


Moral Rationale: Judicial Act, Not Ethnic Cleansing

Genesis 15:16 foretold a 400-year probation until “the iniquity of the Amorites” reached full measure. Leviticus 18 lists child sacrifice, ritual bestiality, and institutionalized occultism—acts that degrade the imago Dei and merit capital sanction (Leviticus 18:24-30). Joshua 6 therefore functions as an enacted court verdict. It is limited in scope (only the “cities of those nations” in Canaan, Deuteronomy 20:16-18) and came with prior warnings: forty years of wilderness headlines, the Red Sea narrative, and Rahab’s testimony that “all who dwell in the land melt in fear of you” (Joshua 2:9). God’s patience and the possibility of repentance are proven by Rahab’s deliverance; had the rest turned, they too would have been spared (cf. Jonah 3).


Jericho as Firstfruits of the Conquest

Numbers 18:12 establishes the theology of firstfruits—giving the initial yield wholly to God. Jericho, first city of the Land, becomes a corporate tithe. Devoting its valuables to the sanctuary (Joshua 6:19) signaled that every subsequent victory would be stewardship, not plunder. Achan’s theft in Joshua 7 confirms this principle; his sin is labeled “ḥērem-trespass,” akin to stealing consecrated offerings (Leviticus 5:15).


Holiness and Contamination Safeguard

Deuteronomy 20:18 states the practical aim: “so that they will not teach you to imitate all their detestable practices.” Israel’s history validates the concern: partial obedience at later sites (Judges 1) produced idolatry (Judges 2:11-13), syncretism (1 Kings 11), and exile (2 Kings 17). The Jericho ban thus protects covenant purity.


Rahab: Mercy in the Midst of Judgment

Rahab embodies God’s universal salvific intent. She is grafted into Israel (Joshua 6:25), listed in Messiah’s genealogy (Matthew 1:5), and praised for faith (Hebrews 11:31; James 2:25). The scarlet cord prefigures the Passover blood and, ultimately, Christ’s atoning cross (1 Peter 1:18-19). Her rescue confirms that God’s judgments include a redemptive invitation.


Typological and Christological Foreshadowing

Jericho’s conquest mirrors eschatological themes: seven priests, seven trumpets, and the seventh-day, sevenfold march anticipate Revelation 8-11’s trumpet judgments culminating in the fall of “Babylon.” The ḥērem anticipates final judgment (Revelation 19), whereas Rahab anticipates the multinational bride of Christ (Ephesians 2:12-13). As ancient Jericho’s walls yielded to divine power, so the “last enemy”—death—yielded at the resurrection (1 Corinthians 15:26, 54).


Canonical and Covenantal Coherence

Joshua 6 rests on Deuteronomy’s covenant charter (Deuteronomy 7; 20) and anticipates prophets’ reflections (Isaiah 13:11). The ḥērem motif resurfaces in 1 Samuel 15, where Saul’s failure costs him the throne, and in Zechariah 14:11, which promises an eschatological reversal—“there will never again be a ban of destruction” in the New Jerusalem.


Practical and Devotional Takeaways

• God’s holiness demands decisive separation from sin (2 Corinthians 6:17).

• Firstfruits obedience safeguards against material idolatry (Proverbs 3:9).

• Mercy is available to all who, like Rahab, confess the living God (Romans 10:13).

Concluding Summary

The destruction commanded in Joshua 6:17 is a multifaceted act: judicial, liturgical, preventative, and prophetic. It vindicates divine justice against entrenched wickedness, consecrates the firstfruits of conquest to the LORD, shields Israel from corrosive idolatry, and foreshadows both universal judgment and gracious redemption in Christ. Far from undermining the character of God, the fall of Jericho magnifies His holiness, faithfulness, and mercy—realities still pertinent for every reader today.
