'Runner' in the Bible

So the watchman called out and informed the king. The king said, "If he is by himself, he brings good news." The runner came ever closer.

The watchman said, "It appears to me that the first runner is Ahimaaz son of Zadok." The king said, "He is a good man, and he comes with good news."

"My days are swifter than a runner, they speed by without seeing happiness.

One runner after another will come to the king of Babylon. One messenger after another will come bringing news. They will bring news to the king of Babylon that his whole city has been captured.
