2 Samuel 18:26 KJV

24And David sat between the two gates: and the watchman went up to the roof over the gate unto 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 tidings in his mouth. And he came apace, and drew near.

26And the watchman saw another man running: and the watchman called unto the porter, and said, Behold another man running alone. And the king said, He also bringeth tidings.

27And the watchman said, Me thinketh the running of the foremost is like the running of Ahimaaz the son of Zadok. And the king said, He is a good man, and cometh with good tidings.

28And Ahimaaz called, and said unto the king, All is well. And he fell down to the earth upon his face before the king, and said, Blessed be the LORD thy God, which hath delivered up the men that lifted up their hand against my lord the king.
