2 Samuel 18:19-23

19Then said Ahimaaz the son of Zadok, Let me now run, and bear the king tidings, how that Jehovah hath avenged him of his enemies. 20And Joab said unto him, Thou shalt not be the bearer of 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 the Cushite, Go, tell the king what thou hast seen. And the Cushite bowed himself unto Joab, and ran. 22Then said Ahimaaz the son of Zadok yet again to Joab, But come what may, let me, I pray thee, also run after the Cushite. And Joab said, Wherefore wilt thou run, my son, seeing that thou wilt have no reward for the tidings? 23But come what may, said he, I will run. And he said unto him, Run. Then Ahimaaz ran by the way of the Plain, and outran the Cushite.
