The prediction of the destruction of the Ammonites, which was effected by Nebuchadnezzar about five years after the destruction of Jerusalem, seems to come in here upon occasion of the king of Babylon's diverting his design against Rabbath, when he turned it upon Jerusalem. Upon this the Ammonites grew very insolent, and triumphed over Jerusalem; but the prophet must let them know that forbearance is no acquittance; the reprieve is not a pardon; their day also is at hand; their turn comes next, and it will be but a poor satisfaction to them that they are to be devoured last, to be last executed.
