Numbers 31 is the chapter where Israel goes to war against Midian at the LORD’s command, and then sets up rules for purity and the division of the spoils. People read it because it is hard to understand: it describes killing on a large scale and raises questions about God, violence, and justice. A careful reading shows that the chapter is less about celebrating conquest than about the LORD’s judgment on Midian’s role in leading Israel into idolatry, and about how a holy people must handle what belongs to God.
Numbers 31 Summary
The chapter opens with God telling Moses to take vengeance on the Midianites, and Moses sends a force of twelve thousand, a thousand from each tribe, under Phinehas the priest. They defeat Midian, kill its males including five kings and the prophet Balaam, and take the women, children, livestock, and goods. Moses is angry that the women were spared, because these women had been used to draw Israel into the sin at Peor, so he orders the killing of the male children and the women who had been with men, while keeping the virgin girls.
The narrative then shifts to purification. The soldiers must camp outside the camp for seven days and cleanse themselves and their captives, and Eleazar sets out how metal and other materials must be purified by fire or water. Next comes the division of the plunder between the warriors and the wider congregation, with a tribute of one in five hundred taken for the LORD from the soldiers’ share and one in fifty from the people’s share given to the Levites. The chapter closes with the officers offering their gold as an atonement offering, which Moses and Eleazar bring into the Tent of Meeting as a memorial before the LORD.
Background and Setting
Numbers is the fourth book of the Pentateuch, traditionally attributed to Moses, who is the central human figure in the chapter. It recounts Israel’s journey through the wilderness between Sinai and the plains of Moab, and Numbers 31 falls near the end of that journey, just before Israel enters the land. The book was shaped in its final form for the people of Israel, and scholars generally date its present form to the exilic or post-exilic period, though its traditions are much older.
The chapter follows the Midianite incident at Peor described in Numbers 25, where Israelite men were drawn into the worship of Baal and into sexual immorality with Moabite and Midianite women, and where a plague struck the camp. Midian is therefore not a random enemy but the people who had tried to undermine Israel’s covenant loyalty to the LORD. Reading the chapter with that background helps explain why the war is framed as the LORD’s vengeance.
Numbers 31 Section by Section
Verses 1-12: The LORD’s Vengeance on Midian
1 The LORD spoke to Moses, saying, 2 “Avenge the children of Israel for the Midianites. Afterward you shall be gathered to your people.”
Numbers 31:1-2 (WEB)
The chapter begins with God’s direct command to Moses, and the word “vengeance” frames the war as judgment on Midian for its part in leading Israel astray. The army is chosen by tribe, and the presence of Phinehas with the sacred vessels and trumpets signals that the campaign is carried out under the LORD’s authority and in the context of worship.
The battle is swift and decisive, and the text reports that Israel killed the Midianite males, their kings, and Balaam. The seizing of captives and plunder and the burning of cities describe the conclusion of an ancient campaign. Readers should take seriously how the text presents this as divine judgment, while recognizing how deeply troubling the scale of the violence is to modern readers.
Verses 13-24: Moses’ Anger and the Rules of Purity
15 Moses said to them, “Have you saved all the women alive? 16 Behold, these caused the children of Israel, through the counsel of Balaam, to commit trespass against the LORD in the matter of Peor, and so the plague was among the congregation of the LORD. 17 Now therefore kill every male among the little ones, and kill every woman who has known man by lying with him. 18 But all the girls, who have not known man by lying with him, keep alive for yourselves.
Numbers 31:15-18 (WEB)
When the army returns with the women alive, Moses is angry, because these women had been the means of Israel’s sin at Peor. His instruction to kill the male children and the women who had known men, while sparing the young girls, is the most difficult part of the chapter for many readers. Scholars and pastors have long debated how this command fits within the ancient laws of war and within the LORD’s concern to remove the influences that led to idolatry.
The purification rules that follow show that holiness required physical and ritual cleansing after contact with death and the spoils of war. Eleazar’s instruction that metals pass through fire and water and that the soldiers wash their clothes reflects the seriousness with which Israel was to keep its camp clean for the presence of the LORD.
22 However the gold, and the silver, the brass, the iron, the tin, and the lead, 23 everything that may withstand the fire, you shall make to go through the fire, and it shall be clean; nevertheless it shall be purified with the water for impurity. All that doesn’t withstand the fire you shall make to go through the water.

Verses 25-47: Dividing the Spoils and the LORD’s Portion
27 And divide the plunder into two parts: between the men skilled in war, who went out to battle, and all the congregation. 28 Levy a tribute to the LORD of the men of war who went out to battle: one soul of five hundred; of the persons, of the cattle, of the donkeys, and of the flocks. 29 Take it from their half, and give it to Eleazar the priest, for the LORD’s wave offering. 30 Of the children of Israel’s half, you shall take one drawn out of every fifty, of the persons, of the cattle, of the donkeys, and of the flocks, of all the livestock, and give them to the Levites, who perform the duty of the LORD’s tabernacle.”
Numbers 31:27-30 (WEB)
The plunder is divided into two halves, with the fighting men receiving one share and the congregation the other. From each side a portion is set aside for the LORD, one from five hundred of the soldiers’ share given to Eleazar, and one from fifty of the people’s share given to the Levites who serve at the tabernacle. This arrangement shows that everything gained in war was ultimately held under God’s ownership and used for worship and service.
The careful counting of livestock and persons, and the precise tallies that follow, emphasize accountability and fairness. Nothing is simply taken; everything is measured and assigned, so that both the warriors and the wider community receive a fair portion while God’s share is honored first.
Verses 48-54: The Officers’ Offering of Gold
48 The officers who were over the thousands of the army, the captains of thousands, and the captains of hundreds, came near to Moses. 49 They said to Moses, “Your servants have taken the sum of the men of war who are under our command, and there lacks not one man of us. 50 We have brought the LORD’s offering, what every man has gotten, of jewels of gold, armlets, and bracelets, signet rings, earrings, and necklaces, to make atonement for our souls before the LORD.”
Numbers 31:48-50 (WEB)
The officers report that not one man of their units was lost, and in gratitude they bring the gold they had taken as an offering to make atonement for their souls. Their confession that they owe their lives to the LORD’s protection turns the chapter’s focus from violence back to gratitude and dependence on God.
The chapter ends with Moses and Eleazar bringing the gold into the Tent of Meeting as a memorial before the LORD. The gesture reminds Israel that even the spoils of a hard-won victory belong to God and are to be returned to his presence.
Key Themes in Numbers 31
- Divine justice: The chapter presents the Midianite war as the LORD’s judgment on a nation that had led Israel into idolatry and sin.
- Holiness and purity: The detailed rules for cleansing people, clothing, and metal show how seriously Israel was to guard the holiness of the camp.
- God’s ownership of spoils: Fixed portions set aside for the priests and Levites teach that everything gained belongs to the LORD first.
- Gratitude and atonement: The officers’ gold offering shows a response of thankfulness and humility after God’s protection.
- Accountability and order: The careful counting and division of plunder reflect a community that values fairness and order before God.
Lessons From Numbers 31 for Today
Few readers will ever face a holy war, but the chapter’s concern with what influences a community can speak to modern life. Just as Midian’s women were used to draw Israel away from the LORD, today’s believers can be pulled away from faithfulness by relationships, entertainment, or habits that quietly shape their loyalty. Numbers 31 invites us to take such influences seriously and to deal with them decisively rather than casually.
The purification rules also invite reflection on how believers should handle what they bring into their homes and lives. A person returning from a painful situation, such as a hard job, a toxic online community, or a damaging friendship, may need intentional time to cleanse and reset before rejoining ordinary life. The chapter’s pattern of separation, washing, and return can guide that kind of renewal.
Finally, the division of spoils and the officers’ gold offering model generosity. When a family receives an inheritance, a raise, or an unexpected gift, the question Numbers 31 raises is whether we will honor God’s share first and remember that what we have ultimately belongs to him.
Questions for Reflection
- What influences in your life have the power to draw your heart away from God, and how are you addressing them?
- Why do you think the LORD’s ownership of the spoils was made so visible in the chapter, and what does that teach about your own resources?
- How do you respond when you read difficult passages about judgment and violence, and what helps you hold them with honesty and humility?
- In what ways have you experienced God’s protection in a hard season, and how did you express gratitude for it?
A Prayer From Numbers 31
Lord, you see the places in my life where I am tempted to drift from you, and you know the influences that pull at my heart. Give me the courage to take those things seriously and the wisdom to deal with them honestly. Teach me to honor you with what I have, to set apart what is yours before I claim anything for myself. Where I have been carried through hard seasons by your protection, make me quick to give thanks. Help me to live as a people set apart for you, both in what I refuse and in what I offer. Amen.
Frequently Asked Questions
Why does God command the war against Midian in Numbers 31?
The chapter presents the war as the LORD’s vengeance on Midian for leading Israel into idolatry and sexual sin at Peor. The Midianites had worked to turn Israel away from its covenant with God. Readers often find this difficult, and many study it alongside Numbers 25 to understand the background.
Why were the young girls spared while the women were killed?
Moses commands that the women who had known men be killed, because they had been used to draw Israel into sin, while the girls who had not known men are kept alive. The text does not explain every detail of this decision, so scholars continue to discuss how it fits within the ancient laws of war.
What is the purpose of the purification rules at the end of the battle?
The rules required soldiers and captives to remain outside the camp and to cleanse themselves after contact with death and the spoils of war. Metals were passed through fire or water and clothes were washed. These steps kept the camp ritually clean for the LORD’s presence.
