2-kings 10:18

Ahab served Baal a little - Jehu had determined to have no worship in Israel but that of the golden calves at Dan and Bethel; therefore he purposes to destroy all the worshippers of Baal: and that he may do it without suspicion, he proclaims a great sacrifice; and that he may do it the more easily, he gathers them all together into one place.

Though we cannot ascribe to Jehu a spirit of true piety (see 2 Kings 10:29), we can well enough understand how the soldier, trained in the Syrian wars, revolted against the unmanly and voluptuous worship of the Dea Syra, and wished to go back to the simple solemn service of Yahweh. These views and feelings it would have been dangerous to declare during the lifetime of Jezebel. Even after her death it was prudent to temporise, to wait until the party of Ahab was crushed politically, before broaching tbe religious question. Having now slain all the issue of Ahab in the kingdom of Israel, and all the influential men of the party 2 Kings 10:7, 2 Kings 10:11, 2 Kings 10:17, Jehu felt that he might begin his reformation of religion. But even now he uses "subtilty" rather than open violence. "Ahab served Baal a little; but Jehu shall serve him much."

10:18 Jehu said - The words being manifestly false, and spoken with a design to deceive, cannot be excused, this being an unmovable principle, That we must not do the least evil, that the greatest good may come.
