2 Kings 15:12 - Joseph Benson’s Commentary on the Old and New Testaments

This was the word of the Lord, Thy sons, &c. How unfaithful soever they proved to God, he faithfully performed the promise which he made to Jehu, whose sons, to the fourth generation, succeeded him in the throne of Israel. But this Shallum put an end to that family, and fulfilled the prophecy of Hosea, (Hosea 1:4,) I will average the blood of Jezreel upon the house of Jehu, and will cause to cease the kingdom of the house of Israel. For though Jehu had a command from God to destroy the house of Ahab, yet because he did it not so much in obedience to God, and with a view to his glory, as to satisfy his own private ambition, and in a way of cruelty quite abhorrent to the divine nature, God cut his family short, as soon as he had fulfilled his promise, and avenged that blood by this man, who slew Zachariah, and the rest of his posterity, if there were any. At least, he made the kingdom to cease in his family, and, not long after, it ceased in all Israel, who were rooted out, and never restored to their own country, as Judah was.
