28 Thus Jehu extirpated Baal out of Israel.

29 Only, the sins of Jeroboam the son of Nebat, who made Israel to sin, from them Jehu departed not: [from] the golden calves that were in Bethel, and that were in Dan. 30 And Jehovah said to Jehu, Because thou hast executed well that which is right in my sight, [and] hast done unto the house of Ahab according to all that was in my heart, thy children of the fourth [generation] shall sit on the throne of Israel. 31 But Jehu took no heed to walk in the law of Jehovah the God of Israel with all his heart; he departed not from the sins of Jeroboam, who made Israel to sin. 32 In those days Jehovah began to cut Israel short; and Hazael smote them in all the borders of Israel; 33 from the Jordan eastward, all the land of Gilead, the Gadites, and the Reubenites, and the Manassites, from Aroer, which is by the river Arnon, both Gilead and Bashan.

Commentary on 2 Kings 10:15-28

(Read 2 Kings 10:15-28)

Is thine heart right? This is a question we should often put to ourselves. I make a fair profession, have gained a reputation among men, but, is my heart right? Am I sincere with God? Jehonadab owned Jehu in the work, both of revenge and of reformation. An upright heart approves itself to God, and seeks no more than his acceptance; but if we aim at the applause of men, we are upon a false foundation. Whether Jehu looked any further we cannot judge. The law of God was express, that idolaters were to be put to death. Thus idolatry was abolished for the present out of Israel. May we desire that it be rooted out of our hearts.

Commentary on 2 Kings 10:29-36

(Read 2 Kings 10:29-36)

It is justly questionable whether Jehu acted from a good principle, and whether he did not take some false steps in doing it; yet no services done for God shall go unrewarded. But true conversion is not only from gross sin, but from all sin; not only from false gods, but from false worships. True conversion is not only from wasteful sins, but from gainful sins; not only from sins which hurt our worldly interests, but from those that support and befriend them; in forsaking which is the great trial whether we can deny ourselves and trust God. Jehu showed great care and zeal for rooting out a false religion, but in the true religion he cared not, took no heed to please God and do his duty. Those that are heedless, it is to be feared, are graceless. The people were also careless, therefore it is not strange that in those days the Lord began to cut Israel short. They were short in their duty to God, therefore God cut them short in their extent, wealth, and power.
