'Messenger' in the Bible

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

But Elisha was sitting in his house, and the elders were sitting with him. Then the king sent a man from before him; but before the messenger came to him, he said to the elders, "Do you see how this son of a murderer has sent to take away my head? Behold, when the messenger comes, shut the door, and hold the door shut against him. Isn't the sound of his master's feet behind him?"

While he was still talking with them, behold, the messenger came down to him. Then he said, "Behold, this evil is from Yahweh. Why should I wait for Yahweh any longer?"

So there went one on horseback to meet him, and said, "Thus says the king, 'Is it peace?'" Jehu said, "What do you have to do with peace? Fall in behind me!" The watchman said, "The messenger came to them, but he isn't coming back."

A messenger came, and told him, "They have brought the heads of the king's sons." He said, "Lay them in two heaps at the entrance of the gate until the morning."
