29 However Jehu did not turn away from the sins of Jeroboam the son of Nebat, who had made Israel sin, that is, from the golden calves that were at Bethel and Dan. 30 And the Lord said to Jehu, "Because you have done well in doing what is right in My sight, and have done to the house of Ahab all that was in My heart, your sons shall sit on the throne of Israel to the fourth generation." 31 But Jehu took no heed to walk in the law of the Lord God of Israel with all his heart; for he did not depart from the sins of Jeroboam, who had made Israel sin. 32 In those days the Lord began to cut off parts of Israel; and Hazael conquered them in all the territory of Israel 33 from the Jordan eastward: all the land of Gilead--Gad, Reuben, and Manasseh--from Aroer, which is by the River Arnon, including Gilead and Bashan. 34 Now the rest of the acts of Jehu, all that he did, and all his might, are they not written in the book of the chronicles of the kings of Israel? 35 So Jehu rested with his fathers, and they buried him in Samaria. Then Jehoahaz his son reigned in his place. 36 And the period that Jehu reigned over Israel in Samaria was twenty-eight years.

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.
