29 But Jehu did not keep himself from all the sins of Jeroboam, the son of Nebat, and the evil he made Israel do; the gold oxen were still in Beth-el and in Dan. 30 And the Lord said to Jehu, Because you have done well in doing what is right in my eyes and effecting all my purpose for the family of Ahab, your sons will be kings of Israel to the fourth generation. 31 But Jehu did not take care to keep the law of the Lord with all his heart: he did not keep himself from the sin which Jeroboam did and made Israel do. 32 In those days the Lord was angry first with Israel; and Hazael made attacks on all the land of Israel, 33 East of Jordan, in all the land of Gilead, the Gadites and the Reubenites and the Manassites, from Aroer by the valley of the Arnon, all Gilead and Bashan. 34 Now the rest of the acts of Jehu, and all he did, and his great power, are they not recorded in the book of the history of the kings of Israel? 35 And Jehu went to rest with his fathers, and was put into the earth in Samaria. And Jehoahaz his son became king in his place. 36 And the time of Jehu's rule 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.
