29 But Jehu did not turn aside from the sins of Jeroboam son of Nebat, which he caused Israel to commit-the golden calves that were in Bethel and in Dan. 30 The Lord said to Jehu, "Because you have done well in carrying out what I consider right, and in accordance with all that was in my heart have dealt with the house of Ahab, your sons of the fourth generation shall sit on the throne of Israel." 31 But Jehu was not careful to follow the law of the Lord the God of Israel with all his heart; he did not turn from the sins of Jeroboam, which he caused Israel to commit. 32 In those days the Lord began to trim off parts of Israel. Hazael defeated them throughout the territory of Israel: 33 from the Jordan eastward, all the land of Gilead, the Gadites, the Reubenites, and the Manassites, from Aroer, which is by the Wadi Arnon, that is, Gilead and Bashan. 34 Now the rest of the acts of Jehu, all that he did, and all his power, are they not written in the Book of the Annals of the Kings of Israel? 35 So Jehu slept with his ancestors, and they buried him in Samaria. His son Jehoahaz succeeded him. 36 The time 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.
