'Messenger' in the Bible

Elisha sent a messenger out to him, who told him, "Go bathe in the Jordan River seven times. Your flesh will be restored for you. Now stay clean!"

Meanwhile, Elisha was sitting in his house, along with the elders, when the king sent a man to kill him, but before the messenger arrived, Elisha told the elders, "Are you watching how this descendant of murderers has ordered my head be cut off? Look, when the messenger arrives, shut the door and hold it to shut them out! Don't you hear the sound of his master's feet right behind him?"

While he was still talking with them, the messenger arrived to see him and delivered the king's message to Elisha, "Look! This evil has come from the LORD! Why should I wait for the LORD anymore?"

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."

When the messenger arrived to report to the king, he said, "They have brought the heads of the king's sons."
