2 Samuel 18:24-28

24And 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.

25And the watchman cried, and told the king. And the king said, If he be alone, there is news in his mouth. And he came on and drew near.

26And 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.

27And 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.

28And Ahimaaz called and said to the king, Peace! And he fell down to the earth on his face before the king, and said, Blessed be Jehovah thy 1God, who has delivered up the men that lifted up their hand against my lord the king.
