Joshua 7:20 Commentary: Achan’s Confession

Joshua 7:20 sits at the climax of a painful scene in Israel’s life. After the stunning victory over Jericho, God had placed the city and all its goods under the herem, a ban that dedicated everything to destruction or the Lord’s treasury (Joshua 6:17, 19). Achan violated that ban by taking a beautiful Babylonian robe, two hundred shekels of silver, and a wedge (or “tongue”) of gold. This was not just theft; it was a breach of covenant loyalty against the God who had given them the victory.

The detection process, tribe by tribe, clan by clan, household by household, likely involved the Urim and Thummim, the sacred lot system used to discern God’s will (see 1 Samuel 10:20, 21 for a parallel). The sin had already caused Israel’s defeat at Ai (Joshua 7:1, 5), and Joshua’s plea to Achan in verse 19, “Give glory to the Lord… and make confession”, makes the purpose of confession clear: it restores the honor and justice of God. Confession in the Old Testament is not only a personal act but also a corporate restoration. The items Achan took, especially the Babylonian robe, represented exactly the kind of luxury and idolatry Israel was meant to renounce. His hidden sin had to be exposed before the community could move forward.

The supplied commentary sources note no significant textual variants for Joshua 7:20. The interlinear shows the standard Masoretic text with the verb sequence va/iyya‘an … va/yyo’mar (“answered … and said”). The Qere/Kethiv issue for the word meaning “mantle” in verse 21 (form of ’r’h) is noted by Keil & Delitzsch but does not affect verse 20. The name appears as “Achan” (Hebrew ‘Akan) in the Masoretic text and as “Achar” in 1 Chronicles 2:7 and some Septuagint manuscripts, but this has no impact on the confession itself.

This verse has been a touchstone for debates about the nature of repentance from the Reformation onward. Reformed interpreters often cite Calvin’s reading of Achan as a caution against equating verbal confession with inward contrition. Wesley and Clarke, in the Arminian tradition, found in Achan’s frankness a model of “ingenuous confession” that could signal genuine, though belated, faith. Throughout church history, the broader story of Achan (vv. 1, 26) has been used as a moral warning about the hiddenness of sin and the necessity of corporate holiness. In modern preaching, the passage is often applied to the communal damage of secret sins and the liberating but costly act of coming clean. The name “Achan” itself became proverbial for one who brings trouble (‘akar), a link the narrator makes explicit in verse 26.

Three-point outline

1. Sin exposed cannot stay hidden. Achan’s confession only comes after God’s methodical selection process singles him out. No sin, however well concealed, escapes divine detection.
2. Confession can be forced or genuine. Achan’s words are true, but is his heart changed? The text leaves room for both readings, reminding us that God sees beyond the verbal admission to the state of the heart.
3. The cost of hidden sin is communal. Achan’s theft brought defeat on Israel. His confession, even if incomplete repentance, allows the community to deal with the breach and move forward.

Five-point outline

1. The slow, inescapable uncovering of sin (vv. 16, 18)
2. Joshua’s pastoral call to give glory through confession (v. 19)
3. Achan’s full but ambivalent response (v. 20)
4. The inventory of hidden guilt (v. 21)
5. The grave consequences for Achan and his household (vv. 22, 26)

Illustration hooks

• Court confession. A defendant admits fault only after forensic evidence leaves no way out, the words are accurate but the motivation is self-preservation, not remorse. Achan’s confession echoes that tension.
• Hidden camera. A person steals from a shop, thinking no one saw, only to be confronted by security footage. The shame of exposure can produce either honest sorrow or bitter resignation.
• The family secret. A hidden sin is discovered after years of covering up. The relief of telling the truth may be mixed with lingering self-justification. Achan’s story invites us to examine our own hidden corners.

Questions your congregation is asking

• Why does God punish sin so severely in this story (death of Achan and his whole family)?
• What if I have sinned secretly and it’s not been exposed? Should I confess even if no one knows?
• Does this mean my private sin can hurt the people around me? How?

This passage forces us to ask hard questions about hidden sin, genuine repentance, and the way our choices affect others. As you work through the questions, resist the temptation to settle too quickly on Achan’s inner state, let the ambiguity of the text press you deeper into your own experience of confession.

Discussion questions

1. What words and phrases does Achan use to describe his sin? How does his confession compare to the forced confessions of Pharaoh (Exodus 10:16) or Saul (1 Samuel 15:24)?
2. Joshua tells Achan to “give glory to the Lord… and make confession” (v. 19). What does it mean that confession itself is a way of glorifying God?
3. Why do you think Achan waited until he was singled out to confess? What does that suggest about his motives?
4. Calvin argued that Achan’s confession was driven by terror; Wesley and Clarke saw genuine repentance. Which view seems more consistent with the rest of the story (consider Achan’s silence during the selection process, vs. his detailed account)?
5. Read Psalm 38:18: “For I will declare my iniquity. I will be sorry for my sin.” How does that voluntary tone contrast with what we see in Joshua 7? What might a true sorrow look like in practice?
6. Achan’s confession did not save him from the death penalty. Does that trouble you? How do you see the difference between forgiveness of sin and the natural consequences of sin?
7. If Achan had confessed immediately after taking the items, do you think the outcome might have been different? Why or why not?
