2 Kings 9:1 - Coke's Commentary on the Holy Bible

Elisha—called one of the children of the prophets— Some of the Jewish doctors have been of opinion, that this messenger was the prophet Jonah, who, upon this supposition, must have been a very young man, because Jeroboam the second, in whose reign Jonah prophesied, did not ascend the throne till about fifty years after this appointment of Jehu to the kingdom of Israel. However this be, it is reasonable to think that Elisha did not go himself to perform this office, either because he was now grown old, and unfit for such a journey, or because he was a person too well known, and not so proper to be employed in an affair which required secrecy.
