2 Kings 9:14-15

14Then Jehu son of Jehoshaphat son of Nimshi conspired against Joram. Now Joram had been in Ramoth Gilead with the whole Israelite army, guarding against an invasion by King Hazael of Syria.

15But King Joram had returned to Jezreel to recover from the wounds he received from the Syrians when he fought against King Hazael of Syria. Jehu told his supporters, “If you really want me to be king, then don’t let anyone escape from the city to go and warn Jezreel.”
