All his might - It is remarkable that this expression, which is not used by the author of Kings in connection with any other king of Israel, should be applied to Jehu, whose ill success in his struggle with Hazael has just been noted, and who submitted to the Assyrians and consented to become a tributary. Perhaps the word is used here in the sense of "personal courage" rather than of "power."

Are they not written in the book of the chronicles - We have no chronicles in which there is any thing farther spoken of this bad man. His reign was long, twenty-eight years; and yet we know nothing of it but the commencement.

For barbarity and hypocrisy Jehu has few parallels; and the cowardliness and baseness of the nobles of Samaria have seldom been equalled. Ahab's bloody house must be cut off; but did God ever design that it should be done by these means? The men were, no doubt, profligate and wicked, and God permitted their iniquity to manifest itself in this way; and thus the purpose of God, that Ahab's house should no more reign, was completely accomplished: see 1 Kings 21:19, 1 Kings 21:21, 1 Kings 21:29. And by this conduct Jehu is said to have executed what was right in God's eyes, 2 Kings 10:30. The cutting off of Ahab's family was decreed by the Divine justice; the means by which it was done, or at least the manner of doing, were not entirely of his appointing: yet the commission given him by the young prophet, 2 Kings 9:7, was very extensive. Yet still many things seem to be attributed to God, as the agent, which he does not execute, but only permits to be done.

Now the rest of the acts of Jehu, and all that he did, and all his might, are they not written in the book of the chronicles of the kings of Israel? Of the preceding kings from the times of Jeroboam, in which their several acts were recorded, and his also.

Conclusion of the history of Jehu's reign. The length of his reign is not given till the end in this instance (2 Kings 10:36), contrary to the usual custom in our books, because his ascent of the throne is not expressly mentioned in what precedes; but the general character of his reign is given in immediate connection with the account of his anointing and of the extermination of Ahab's dynasty.

Now the rest of the acts of Jehu, and all that he did, and all his might, are they not written in the book of the chronicles of the kings of Israel?

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.
