2 Samuel 18:24-27

24While David was sitting between the inner and outer gates of the town, the watchman climbed to the roof of the gateway by the wall. As he looked, he saw a lone man running toward them.

25He shouted the news down to David, and the king replied, “If he is alone, he has news.” As the messenger came closer,

26the watchman saw another man running toward them. He shouted down, “Here comes another one!” The king replied, “He also will have news.”

27“The first man runs like Ahimaaz son of Zadok,” the watchman said. “He is a good man and comes with good news,” the king replied.
