Meaning of "devoted things" in Joshua 6:18?
What does Joshua 6:18 mean by "devoted things" and why are they significant?

Canonical Text

Joshua 6:18: “But keep yourselves from the devoted things, lest you set them apart for destruction. If you take any of the devoted things, you will make the camp of Israel liable to destruction and bring trouble upon it.”


Historical Setting In The Joshua Narrative

Jericho is the first Canaanite city Israel confronts after crossing the Jordan (Joshua 3–6). As the “firstfruits” of the land (cf. Exodus 23:19), everything within Jericho belongs uniquely to Yahweh. That status explains why gold, silver, bronze, and iron were to be deposited in Yahweh’s treasury (Joshua 6:19), whereas all other plunder—people, livestock, and ordinary goods—was to be destroyed.


Devoted Things As Firstfruits And The Holy War Ban

1. Firstfruits Principle: By dedicating Jericho entirely to God, Israel acknowledged Him as the true owner of Canaan (Leviticus 25:23).

2. Holy War Ban: Devotion to destruction underscored the moral gravity of Canaanite idolatry (Deuteronomy 20:17-18) and preserved Israel from syncretism.


Violation And Consequence: The Sin Of Achan (Joshua 7)

Achan’s illicit appropriation of a Babylonian cloak, 200 shekels of silver, and a 50-shekel gold bar breached the ḥērem. The result was Israel’s defeat at Ai and corporate liability (“Israel has sinned,” Joshua 7:11). God’s judgment fell on Achan and his household, illustrating that private sin can generate communal fallout.


Theological Significance: Holiness, Covenant Loyalty, And Sin

1. Divine Holiness: Yahweh cannot coexist with what He has decreed unclean (Isaiah 6:3-5).

2. Covenant Loyalty (ḥesed): Obedience to ḥērem was an expression of Israel’s love for God (Deuteronomy 6:5-7).

3. Sin’s Contagion: Like leaven (1 Corinthians 5:6-8), unaddressed sin permeates an entire people.


Typological And Christological Dimensions

Jericho’s ḥērem anticipates the cross. Just as condemned objects were destroyed outside Jericho’s walls, so Christ “became a curse for us” (Galatians 3:13). He bore divine wrath so believers might become “a people for His own possession” (Titus 2:14). The New Testament echo surfaces in Acts 5:1-11: Ananias and Sapphira’s fate parallels Achan’s, reinforcing the seriousness of deceit within God’s redeemed community.


Archaeological Corroboration From Jericho

• Stratigraphy at Tell es-Sultan (Jericho) reveals a collapsed mud-brick wall at City IV, dated c. 1400 BC, fitting a 15th-century Exodus–Conquest chronology.

• Large grain jars discovered intact (John Garstang, 1930s; Bryant Wood, 1990s) imply the city fell quickly and in spring (cf. Joshua 3:15), supporting a scenario where spoils remained untouched—precisely what ḥērem required.

• A layer of ash roughly three feet thick demonstrates the commanded burning (Joshua 6:24).


Ethical And Behavioral Insights

1. Ownership: Recognizing that every material good ultimately belongs to God safeguards against covetousness.

2. Corporate Responsibility: Leaders and laity alike bear mutual accountability for holiness.

3. Swift Discipline: Delay in addressing sin imperils communal mission and witness.


Practical Application For Contemporary Believers

• Guard the Heart: Modern “devoted things” include any idol—money, sex, power—that competes with loyalty to Christ (1 John 5:21).

• Stewardship: Yield the “first and best” of one’s income, talents, and time to God, mirroring Jericho’s firstfruits.

• Community Purity: Church discipline, exercised lovingly and biblically (Matthew 18:15-17), maintains collective holiness.


Concluding Synthesis

In Joshua 6:18 “devoted things” are items irrevocably assigned to Yahweh, either for sacred treasury use or for destruction, signifying His ownership, holiness, and right to judge. Their significance radiates through Israel’s history, foreshadows the atoning work of Christ, instructs the church on purity, and reinforces the perennial truth that wholehearted devotion to God is both the duty and joy of His redeemed people.
