'Messenger' in the Bible

Elisha sent a messenger to him, saying, "Go, you must wash seven times in the Jordan, then your flesh shall return to you, and you shall be clean."

Now Elisha [was] sitting in his house and the elders [were] sitting with him, and [the king] dispatched a man from before him, but before the messenger came to him, he said to the elders, "Did you see that this son of a murderer has sent to remove my head? Look, when the messenger comes, close the door; and you must {hold the door closed against him}. [Is] not the sound of the feet of his master behind him?"

While he [was] still speaking with them, suddenly the messenger [was] coming down to him, and he said, "Look this trouble [is] from Yahweh. Why should I wait for Yahweh any longer?"

So the rider of the horse went out to meet him, and he said, "Thus the king asks, 'Is it peace?'" Then Jehu said, "{What do you have to do with peace}? Turn after me." Then the watchman reported, saying, "The messenger went up to them, but he did not return."

Then the messenger came and told him, saying, "They have brought the heads of the king's sons," and he said, "Put them [in] two piles [at] the entrance of the gate until morning."
