15 "Have you allowed all the women to live?" he asked them. 16 "They were the ones who followed Balaam's advice and enticed the Israelites to be unfaithful to the Lord in the Peor incident, so that a plague struck the Lord's people.
15 Moses said to them, "Have you let all the women live? 16 Behold, these, on Balaam's advice, caused the people of Israel to act treacherously against the Lord in the incident of Peor, and so the plague came among the congregation of the Lord.
15 "What's this! You've let these women live! 16 They're the ones who, under Balaam's direction, seduced the People of Israel away from God in that mess at Peor, causing the plague that hit God's people.
15 And Moses said to them: "Have you kept all the women alive? 16 Look, these women caused the children of Israel, through the counsel of Balaam, to trespass against the Lord in the incident of Peor, and there was a plague among the congregation of the Lord.
15 "Why have you let all the women live?" he demanded. 16 "These are the very ones who followed Balaam's advice and caused the people of Israel to rebel against the Lord at Mount Peor. They are the ones who caused the plague to strike the Lord 's people.
Matthew Henry's Commentary on Numbers 31:15-16
Commentary on Numbers 31:13-18
(Read Numbers 31:13-18)
The sword of war should spare women and children; but the sword of justice should know no distinction, but that of guilty or not guilty. This war was the execution of a righteous sentence upon a guilty nation, in which the women were the worst criminals. The female children were spared, who, being brought up among the Israelites, would not tempt them to idolatry. The whole history shows the hatefulness of sin, and the guilt of tempting others; it teaches us to avoid all occasions of evil, and to give no quarter to inward lusts. The women and children were not kept for sinful purposes, but for slaves, a custom every where practised in former times, as to captives. In the course of providence, when famine and plagues visit a nation for sin, children suffer in the common calamity. In this case parents are punished in their children; and for children dying before actual sin, full provision is made as to their eternal happiness, by the mercy of God in Christ.
