'Come in Peace' in the Bible

Now the watchman was standing on the tower in Jezreel and he saw the crowd with Jehu as he approached, and said, “I see a company.” And Joram said, “Send a horseman to meet them and have him ask, ‘Do you come in peace?’”

So a horseman went out, greeted Jehu and said, "This is what the king said: "Have you come in peace?'" But Jehu responded, "What do you have to do with peace? Fall in behind me." The watchman reported, "The messenger arrived there, but he hasn't returned."

Then Joram sent out a second horseman, who went out to them and said, "This is what the king said: "Have you come in peace?'" Jehu responded, "What do you have to do with peace? Fall in behind me."

As Jehu entered in at the gate, she said, "Do you come in peace, Zimri, you murderer of your master?"
