And the Lord said unto Jehu - Probably by the mouth of Elisha. To a certain extent Jehu's measures were acts of obedience, for which God might see fit to assign him a temporal reward.

Thy children ... - This was accomplished in the persons of Jehoahaz, Joash, Jeroboam, and Zachariah, the son, grandson, great-grandson, and great-great-grandson of Jehu (compare the marginal references). No other family sat upon the throne of Israel so long. The house of Omri, which furnished four kings, held the crown for three generations only and for less than 50 years - that of Jehu reigned for five generations and for more than 100 years.

Thy children of the fourth generation - These four descendants of Jehu were Jehoahaz, Jehoash, Jeroboam the second, and Zechariah; see 2 Kings 14 and 15. This was all the compensation Jehu had in either world, as a recompense of his zeal for the Lord.

And the Lord said unto Jehu,.... By a prophet, he not being one himself; and this is generally supposed, by the Jews (w), to be Jonah the son of Amittai:

because thou hast done well in executing that which is right in mine eyes: in rooting out the idolatry of Baal, which was right in the sight of God, and was materially a good work, though it might not be done from a good principle, nor every step taken in doing it justifiable:

and hast done unto the house of Ahab according to all that was in mine heart: that he had decreed within himself should be done, and had foretold by his prophets would be done, the doing of which was acceptable and well pleasing to him:

thy children of the fourth generation shall sit on the throne of Israel; as they did, namely, Jehoahaz, Joash, Jeroboam, and Zachariah, though the last reigned but six months, just enough to fulfil this promise.

(w) Seder Olam Rabba, c. 19.

Jehu is promised the possession of the throne to the fourth generation of his sons for having exterminated the godless royal house of Ahab (vid., 2 Kings 15:12). The divine sentence, "because thou hast acted well to do right in mine eyes. (because thou) hast done as it was in my heart to the house of Ahab," refers to the deed as such, and not to the subjective motives by which Jehu had been actuated. For it is obvious that it had not sprung from pure zeal for the honour of the Lord, from the limitation added in 2 Kings 10:31 : "but Jehu did not take heed to walk in the law of Jehovah with all his heart, and did not depart from the sins of Jeroboam."

And the LORD said unto Jehu, Because thou hast done well in executing that which is right in mine eyes, and hast done unto the house of Ahab according to all that was in mine heart, thy {l} children of the fourth generation shall sit on the throne of Israel.

(l) Thus God approves and rewards his zeal, in executing God's judgment, though his wickedness was later punished.

10:30 Done well - In part, and so far as is here expressed.

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.
