II Kings 9:14-15

So Jehu the son of Jehoshaphat, the son of Nimshi, conspired against Joram. (Now Joram had been defending Ramoth Gilead, he and all Israel, against Hazael king of Syria. But King Joram had returned to Jezreel to recover from the wounds which the Syrians had inflicted on him when he fought with Hazael king of Syria.) And Jehu said, “If you are so minded, let no one leave or escape from the city to go and tell it in Jezreel.”
