'Messenger' in the Bible

Elisha sent a messenger to him, saying, “Go and wash in the Jordan seven times, and your flesh will be restored to you and you will be clean.”

Now Elisha was sitting in his house, and the elders were sitting with him. And the king sent a man ahead of him [to behead Elisha]; but before the messenger arrived, Elisha told the elders, “Do you see how this son of [Jezebel] a murderer has sent [a man] to remove my head? Look, when the messenger comes, shut the door and hold it securely against him. Is not the sound of his master’s feet [just] behind him?”

While Elisha was still talking with them, the messenger came down to him [followed by the king] and the king said, “This evil [situation] is from the Lord! Why should I wait for [help from] the Lord any longer?”

So the horseman went to meet him and said, “Thus says the king: ‘Do you come in peace?’” And Jehu said, “What have you to do with peace? Rein in behind me.” And the watchman reported, “The messenger approached them, but he has not returned.”

When a messenger came and told him, “They have brought the heads of the king’s sons,” he said, “Put them in two heaps at the entrance of the city gate until morning.”
