2 Kings 9:15-17
9:15 But 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.”
9:16 Jehu drove his chariot to Jezreel, for Joram was recuperating there. (Now King Ahaziah of Judah had come down to visit Joram.)
9:17 Now the watchman was standing on the tower in Jezreel and saw Jehu’s troops approaching. He said, “I see troops!” Jehoram ordered, “Send a rider out to meet them and have him ask, ‘Is everything all right?’”
