2 Samuel 18:21-26 New King James Version (NKJV)

21. Then Joab said to the Cushite, “Go, tell the king what you have seen.” So the Cushite bowed himself to Joab and ran.

22. And Ahimaaz the son of Zadok said again to Joab, “But whatever happens, please let me also run after the Cushite.”So Joab said, “Why will you run, my son, since you have no news ready?”

23. “But whatever happens,” he said, “let me run.”So he said to him, “Run.” Then Ahimaaz ran by way of the plain, and outran the Cushite.

24. Now David was sitting between the two gates. And the watchman went up to the roof over the gate, to the wall, lifted his eyes and looked, and there was a man, running alone.

25. Then the watchman cried out and told the king. And the king said, “If he is alone, there is news in his mouth.” And he came rapidly and drew near.

26. Then the watchman saw another man running, and the watchman called to the gatekeeper and said, “There is another man, running alone!”And the king said, “He also brings news.”
