Verse 16. - To commit trespass. לִמְסָר־מַעַל See on verse 5. The word מסר seems to be used here much as the English word "levy" is used in such a phrase as "levying" war against a person.

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.Behold, these caused the children of Israel, through the counsel of Balaam,.... Who advised the Midianites to send their women into the camp of Israel, and allure them to uncleanness, and so draw them into idolatry, which counsel they followed and it succeeded; for, by this means, they were brought

to commit trespass against the Lord in the matter of Peor; by worshipping Baalpeor, the god of the Moabites and Midianites; whereby they transgressed the commandment of God, which forbid them having and worshipping any other gods besides him, and is a sin highly offensive to him, being greatly derogatory to his honour and glory:

and there was a plague among the congregation of the Lord; for that sin; and in that plague died 24,000 persons, Numbers 25:9.
