Joshua 6:17 Commentary: Devoted to God, Rahab Spared

Jericho was the first fortified Canaanite city Israel encountered after crossing the Jordan. Its capture was not merely a military event but a theological one. The term cherem (Strong’s H2764) carried the sense of “ban” or “devoted thing”, something withdrawn from common use and given wholly to God. In ancient Near Eastern warfare, victors often devoted captured cities to their gods. For Israel, the herem was commanded by Yahweh as an act of judgment on the Canaanites, whose sins had “filled up their iniquities” (Gen 15:16; see also Lev 18:24-28).

Jericho received the weight of this judgment first. Barnes and Calvin both point out that the first city taken was to be a firstfruits offering. By destroying it entirely and taking no spoils, Israel declared that the whole land came from God’s hand. The city’s walls fell by miracle, not human strength, so the victory clearly belonged to Yahweh alone. The sparing of Rahab, a Canaanite prostitute who hid the spies, broke the pattern of total destruction. Her house marked with a scarlet cord (Joshua 2:18-21) became a zone of safety. This exception was grounded in her faith and her act of allegiance to Israel’s God. She and her family were “saved alive” and later incorporated into the people of Israel (Josh 6:25).

The wider context reinforces the unique status of Jericho. Silver, gold, and metal vessels were not destroyed but consecrated to the sanctuary (v.19). The city itself was never to be rebuilt (v.26). These details show that the herem was both a judgment and a holy offering, a solemn act that set the pattern for how Israel was to receive the land.

The consulted commentaries note no significant textual variants for Joshua 6:17. The reading is stable across Hebrew manuscripts and ancient versions (Septuagint, Vulgate). The key term cherem is consistently rendered “accursed” or “devoted” in English translations, reflecting the same underlying form.

From the early church onward, Joshua 6:17 has been read as a striking intersection of judgment and mercy. Origen and Augustine saw in Rahab a type of the church, a sinful outsider saved by faith and the sign of the scarlet cord (interpreted as the blood of Christ). In the Reformation, Calvin and Luther emphasized the herem as a demonstration of God’s sovereignty and the seriousness of firstfruits devotion. Matthew Henry and later Wesleyan commentators stressed both the terror of the judgment and the grace extended to Rahab, holding them together as parts of one divine act. In modern interpretation, the passage has prompted deeper reflection on the ethics of holy war and the nature of divine judgment, with many Christians reading it as a pointer to the ultimate judgment that fell on Christ, the one who bore God’s curse so that outsiders like Rahab could be brought in. The book of Hebrews (11:31) and James (2:25) both celebrate Rahab as a model of living faith.

Three-point outline

1. The Firstfruits Principle. The first city taken belonged wholly to God. This calls believers to give God the first and best of what they receive, acknowledging Him as the giver of all victory.
2. Judgment and Holiness. God’s holiness consumes what stands against Him. The herem is a stark reminder that sin invites divine judgment, but it also sets the stage for mercy.
3. Grace for the Unexpected. Rahab, a prostitute and an outsider, is saved because she turned toward the God of Israel. Grace can reach anyone, anywhere, who trusts in Him.

Five-point outline

1. God Claims the First City as His Own.
2. Total Devotion Required: No Plunder, No Profit.
3. The Danger of Taking What Is Set Apart (v.18).
4. Rahab’s Faith Made Visible in Action.
5. The City Falls, but Mercy Endures.

Illustration hooks

• The first paycheck. When someone gets their first salary and decides to give a major portion to God before spending any, that is the firstfruits principle. It costs something.
• A demolition order. A city condemned for safety: everything inside must be removed or destroyed. Some things cannot be salvaged; the whole structure must come down. God’s judgment on Jericho was final, but He marked one house for salvation.
• The outsider welcomed in. A person who was once hostile to a community is given protection because of a single act of trust. Rahab’s story still surprises.

Questions your congregation is asking

• “Why would God command the death of every person, including children and animals?”
• “What does this say about God’s character? Is He loving or violent?”
• “How can Rahab’s story, a prostitute and an outsider, be relevant to my life today?”

This passage confronts us with God’s holiness and His mercy. The command to destroy Jericho was not arbitrary; it was an act of judgment on a culture that had rejected God for centuries. Yet in the midst of judgment, God provided a way of escape for anyone who would trust Him, even a Canaanite prostitute. Use these questions to help your group dig into the text and apply it.

Discussion questions

1. Read Joshua 6:17 carefully. What does it mean that the city is “devoted” to the Lord? How does Leviticus 27:28-29 help explain this concept?
2. Why was Jericho treated differently from other cities in the conquest? (See also Deuteronomy 20:10-17 for comparison.)
3. What reasons do the commentators give for the herem on Jericho? Which reason strikes you most?
4. Rahab is singled out for mercy. What did she do that set her apart? How does her faith (Hebrews 11:31) connect to her actions?
5. If you had been an Israelite soldier, how would you have felt about killing everyone but sparing one household? What does this reveal about obedience and trust?
6. In what areas of your life is God asking you to “devote” something wholly to Him, not holding back or taking a share for yourself?
7. How does this story shape your understanding of God’s judgment and His grace? Where do you see yourself in the story, among Israel, or like Rahab, an outsider receiving mercy?
