'Running' in the Bible

And David sat between the two gates; and the watchman went up to the roof of the gate, on to the wall, and lifted up his eyes and looked, and behold, a man running alone.

And the watchman saw another man running; and the watchman called to the porter and said, Behold a man running alone. And the king said, He also is a bearer of news.

And the watchman said, I see the running of the foremost like the running of Ahimaaz the son of Zadok. And the king said, He is a good man; and comes with good news.
