2 Kings 9:14

So Jehu the son of Jehoshaphat the son of Nimshi conspired against Joram,.... He and the captains with him entered into a confederacy to depose Joram, and set him up as king:

now Joram had kept Ramothgilead, he and all Israel, because of Hazael king of Syria; having taken it, he left his army in it, under the command of his captains, of which Jehu was the chief, to keep it from the king of Syria; which gave Jehu a fairer opportunity, having the army at his command, and at a distance from Joram, of forming a conspiracy against him.
