2 Kings 10:18 - Matthew Poole's English Annotations on the Holy Bible

Jehu gathered all the people together; by their representatives, their elders or rulers, as was usual; to whom he imparts his mind; and they being generally corrupt, and timeservers, and such as had no sense of religion in them, durst not oppose his resolution, but seemed to comply with it. Jehu shall serve him much: as if he had said, My quarrel is only with Ahab's family, and not with Baal; which my actions shall manifest; which words being manifestly false, and spoken with a design to deceive, cannot be excused from sin, though they were uttered with a pious intention; this being an unmovable principle, that we must not do the least evil of sin, that the greatest good may come, Romans 3:8. And if Jehonadab did concur with Jehu herein, it was a human infirmity.
