Numbers 31:2 - Matthew Poole's English Annotations on the Holy Bible

Of the Midianites, for their malicious designs and practices against Israel, both by hiring Balaam to curse them, and by sending their women to enslave them. The Moabites also were guilty, but God out of his own good pleasure, and in kindness to Lot, was pleased to spare them, the rather, because the measure of their iniquity was not yet full.
