Charles Ellicott Commentary 1 Kings 16:7

"And moreover by the prophet Jehu the son of Hanani came the word of Jehovah against Baasha, and against his house, both because of all the evil that he did in the sight of Jehovah, to provoke him to anger with the work of his hands, in being like the house of Jeroboam, and because he smote him." — 1 Kings 16:7 (ASV)

And also. —This second reference to the prophecy of Jehu seems to be a note of the historian—perhaps added chiefly for the sake of the last clause, which shows that Baasha’s act, though foretold, was not thereby justified.
