2 Samuel 18:24-27

24David was sitting between the city gates when the watchman went up to the roof of the city gate and over to the wall. The watchman looked out and saw a man running alone.

25He called out and told the king. The king said, “If he’s alone, he bears good news.” As the first runner came closer,

26the watchman saw another man running. He called out to the gatekeeper, “Look! Another man is running alone!” “This one is also bringing good news,” said the king.

27The watchman said, “The way the first man runs looks to me like the way Ahimaaz son of Zadok runs.” “This is a good man; he comes with good news,” the king commented.
