Meanwhile, Joram and the entire army were defending Ramoth Gilead against Hazael king of Aram. Except that Joram had pulled back to Jezreel to convalesce from the injuries he got from the Arameans in the battle with Hazael king of Aram.
Jehu said, "If you really want me as king, don't let anyone sneak out of the city and blab the news in Jezreel."
