2 Samuel 18:21-25

21Then said Joab to Cushi, Go tell the king what thou hast seen. And Cushi bowed himself to Joab, and ran. 22Then said Ahimaaz the son of Zadok yet again to Joab, But however, let me also, I pray thee, run after Cushi. And Joab said, Why wilt thou run, my son, seeing that thou hast no tidings ready?12 23But however, said he, let me run. And he said to him, Run. Then Ahimaaz ran by the way of the plain, and outran Cushi. 24And David sat between the two gates: and the watchman went up to the roof over the gate to the wall, and lifted up his eyes, and looked, and behold a man running alone. 25And the watchman called, and told the king. And the king said, If he is alone, there is tidings in his mouth. And he came apace, and drew near.
