2 Samuel 18:23

19Then said Ahimaaz the son of Zadok, Let me now run, and bear the king tidings, how that the Lord hath avenged him of his enemies.

20And Joab said unto him, Thou shalt not bear tidings this day, but thou shalt bear tidings another day: but this day thou shalt bear no tidings, because the king’s son is dead.

21Then said Joab to Cushi, Go tell the king what thou hast seen. And Cushi bowed himself unto Joab, and ran.

22Then said Ahimaaz the son of Zadok yet again to Joab, But howsoever, let me, I pray thee, also run after Cushi. And Joab said, Wherefore wilt thou run, my son, seeing that thou hast no tidings ready?

23But howsoever, said he, let me run. And he said unto him, Run. Then Ahimaaz ran by the way of the plain, and overran Cushi.

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.
