And because he killed him - This the Vulgate understands of Jehu the prophet, put to death by Baasha: Ob hanc causam occidit eum, hoe est. Jehu filium Hanani prophetam; "On this account he killed him, that is, Jehu the prophet, the son of Hanani." Some think Baasha is intended, others Jeroboam, and others Nadab the son of Jeroboam. This last is the sentiment of Rab. Sol. Jarchi, and of some good critics. The order is here confused; and the seventh verse should probably be placed between the 4th and 5th.
The natural position of this verse would be after 1 Kings 16:4 and before 1 Kings 16:5. But it may be regarded as added by the writer, somewhat irregularly, as an afterthought; its special force being to point out that the sentence on Baasha was intended to punish, not only his calf-worship, but emphatically his murder of Jeroboam and his family. Though the destruction of Jeroboam had been foretold, and though Baasha may be rightly regarded as God‘s instrument to punish Jeroboam‘s sins, yet, as he received no command to execute God‘s wrath on the offender, and was instigated solely by ambition and self-interest, his guilt was just as great as if no prophecy had been uttered. Even Jehu‘s commission 2 Kings 9:5-10 was not held to justify, altogether, his murder of Jehoram and Jezebel.
