Numbers 31 records Israel’s war against the Midianites, a people who had led Israel into idolatry and sexual sin at Peor. People read this chapter because it is one of the hardest passages in the Old Testament, and they want to know what it says, why it was written, and how Christians should understand God’s command to destroy a nation. In short, the chapter tells of a divinely commanded campaign of judgment, followed by careful rules for purification and a fair division of the plunder.
Numbers 31 Summary
The chapter opens with God telling Moses to avenge Israel against Midian, and Moses sends a force of twelve thousand, a thousand from each tribe, with Phinehas the priest carrying the sacred trumpets. They defeat Midian, kill its males including five kings and the prophet Balaam, and burn its towns and camps. Moses is angry when the army returns with the captive women and children, because the women had drawn Israel into the sin at Peor, and he orders the Israelite soldiers to kill the males and the women who had been with men, while keeping the young girls alive.
The middle of the chapter turns to ritual cleansing. The soldiers stay outside the camp for seven days, purify themselves and their captives, and purify their goods, with gold, silver and metal passed through fire and the rest through water. Then God commands that the plunder be divided between the warriors and the wider congregation, with a tribute of one in five hundred given to the priest and one in fifty given to the Levites. The chapter closes with the officers offering their gold as an atoning gift, which is brought into the Tent of Meeting as a memorial.
Background and Setting
The book of Numbers is the fourth book of the Pentateuch, the first five books of the Bible, and it is traditionally attributed to Moses, who is named throughout the chapter. Most scholars date its final form to the period after Israel’s time in the wilderness, perhaps during or after the Babylonian exile, while preserving older traditions. Numbers describes the journey of the Israelites from Sinai toward the promised land, and this chapter takes place on the plains of Moab, just across the Jordan from Jericho, at the very edge of Canaan.
The chapter is set within a larger narrative about Israel’s wilderness generation and its covenant identity. Chapter 25 told how Israel joined in Baal worship at Peor, and Numbers 31 is God’s answer to that sin, marking Midian as the instrument of that temptation. The book was written for a community that needed to understand its origins, its laws and its calling to be a holy people set apart from the surrounding nations.
Numbers 31 Section by Section
Verses 1-12: The Campaign Against Midian
2 “Avenge the children of Israel for the Midianites. Afterward you shall be gathered to your people.” 3 Moses spoke to the people, saying, “Arm men from among you for the war, that they may go against Midian, to execute the LORD’s vengeance on Midian.
Numbers 31:2-3 (WEB)
They fought against Midian, as the LORD commanded Moses. They killed every male.
Numbers 31:7 (WEB)
God commands Moses to carry out vengeance on Midian, and the response is an organized military campaign rather than a spontaneous raid. The text stresses that the battle is done “as the LORD commanded Moses,” so the entire operation is presented as obedience to God’s direction. The reader should notice how the chapter frames the war as a matter of God’s justice against a people who had seduced Israel into worship of other gods.
The narrative is brief and dry, which is part of its force. The fighters kill the males, the kings and Balaam, and they take captives and goods, and the summary does not linger over the violence. Verse 12 shows the spoils being brought back to Moses, Eleazar and the congregation, so the account remains focused on Israel’s life as a community under God’s authority.
Verses 13-24: Moses’ Anger and the Rules of Purification
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)
“Encamp outside of the camp seven days. Whoever has killed any person, and whoever has touched any slain, purify yourselves on the third day and on the seventh day, you and your captives.
Numbers 31:19 (WEB)
When Moses meets the army he is angry that the women were spared, because the text identifies them as the means by which Israel was led into the sin at Peor. His command to kill the males and the women who had known a man, while keeping the young girls, reflects the law’s concern for holiness and for the boundaries of the people. Scholars and readers alike find this portion difficult, and it is wise to read it carefully rather than to treat it lightly.
Verses 19 through 24 turn to purification. Those who had touched the dead were to stay outside the camp for seven days and cleanse themselves on the third and seventh days, and every object was to be cleansed according to its material. The passage shows that God cares for ritual purity as a way of living in His presence, and that even a victory must be handled within the holiness required of the camp.
Verses 25-41: The Division of the Plunder
And divide the plunder into two parts: between the men skilled in war, who went out to battle, and all the congregation.
Numbers 31:27 (WEB)
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 31:28-30 (WEB)
God instructs that the plunder be divided evenly between the warriors and the rest of the congregation, which reflects a principle of shared responsibility. The army’s share was then taxed at one in five hundred, and that portion went to the priests as an offering to the LORD, while the congregation’s share yielded one in fifty for the Levites. The division shows that the law treats both the fighters and the wider community as participants in the outcome.
The numbers are large, with hundreds of thousands of animals and tens of thousands of people counted, and the careful accounting is itself a theme. The text insists that everything be counted and assigned to God’s purposes, which teaches that the blessings of victory belong to God first and are shared within His community.
Verses 42-54: The Officers’ Offering
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)
Moses and Eleazar the priest took the gold of the captains of thousands and of hundreds, and brought it into the Tent of Meeting, for a memorial for the children of Israel before the LORD.
Numbers 31:54 (WEB)
The officers come to Moses to report that not one man was lost, and they bring their gold as an offering to make atonement for their souls. The gesture expresses gratitude and humility, and it shows that the warriors recognized their survival as a gift. The gold is taken into the Tent of Meeting as a memorial before the LORD, which keeps the victory connected to worship.
The closing verses show the army as more than conquerors. Their gold becomes a lasting reminder before God, and the chapter ends by directing Israel’s attention back to the worship that defines the nation. The reader is left with a sense that victory must always lead to gratitude and acknowledgment of God’s sovereignty.

Lessons From Numbers 31 for Today
A reader facing a hard passage may be tempted either to skip it or to turn it into a weapon. A more faithful response is to read it within the whole witness of Scripture, which reveals a God who judges sin and also loves mercy, and to ask what it means for the church to take sin seriously. Many Christians today hold this passage with humility, admitting that they cannot fully explain every detail while still trusting God’s character as revealed in Christ.
The chapter also speaks to ordinary faithfulness. The careful purification rules and the honest accounting of the spoils show that God cares about daily integrity, not just dramatic moments. A believer who returns from a stressful workweek or a difficult family conflict can find something instructive in the call to cleanse, count and give back what belongs to God.
