He said to Jehoshaphat, Wilt thou go up with me, &c.? It is not strange that Ahab should desire the assistance of so pious and prosperous a neighbour as Jehoshaphat, and should wish to draw him in to join him in this expedition for the recovery of Ramoth-Gilead. Even bad men have often coveted the friendship of the good; but it is strange that Jehoshaphat should go so entirely into Ahab's interests as to say, I am as thou art, and my people as thy people That is, I will heartily and effectually join with thee; and my forces shall be at thy service, as much as thine own.
