2 Kings 9:16

14 Thus Jehu son of Jehoshaphat, the son of Nimshi, conspired against Joram. (Now Joram and all Israel had been defending Ramoth-gilead against Hazael king of Aram,

15 but King Joram had returned to Jezreel to recover from the wounds he had suffered at the hands of the Arameans in the battle against Hazael their king.) So Jehu said, “If you commanders wish to make me king, then do not let anyone escape from the city to go and tell it in Jezreel.”

16 Then Jehu got into his chariot and went to Jezreel, because Joram was laid up there and Ahaziah king of Judah had gone down to see him.

17 Now the watchman standing on the tower in Jezreel saw Jehu’s troops approaching, and he called out, “I see a company of troops!” “Choose a rider,” Joram commanded. “Send him out to meet them and ask, ‘Have you come in peace?’”

18 So a horseman rode off to meet Jehu and said, “This is what the king asks: ‘Have you come in peace?’” “What do you know about peace?” Jehu replied. “Fall in behind me.” And the watchman reported, “The messenger reached them, but he is not coming back.”
