2 Samuel 18:23

20 And 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.

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

22 Then 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?

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

24 And 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.

25 And 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.

26 And 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.
