29 He did not, however, destroy the gold calves at Bethel and Dan, with which Jeroboam son of Nebat had caused Israel to sin. 30 Nonetheless the Lord said to Jehu, "You have done well in following my instructions to destroy the family of Ahab. Therefore, your descendants will be kings of Israel down to the fourth generation." 31 But Jehu did not obey the Law of the Lord, the God of Israel, with all his heart. He refused to turn from the sins that Jeroboam had led Israel to commit. 32 At about that time the Lord began to cut down the size of Israel's territory. King Hazael conquered several sections of the country 33 east of the Jordan River, including all of Gilead, Gad, Reuben, and Manasseh. He conquered the area from the town of Aroer by the Arnon Gorge to as far north as Gilead and Bashan. 34 The rest of the events in Jehu's reign-everything he did and all his achievements-are recorded in 35 When Jehu died, he was buried in Samaria. Then his son Jehoahaz became the next king. 36 In all, Jehu reigned over Israel from Samaria for 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.
