"You are not the one to take the news today," Joab told him. "You may take the news another time, but you must not do so today, because the king's son is dead."
Then Joab said to a Cushite, "Go, tell the king what you have seen." The Cushite bowed down before Joab and ran off.
Ahimaaz son of Zadok again said to Joab, "Come what may, please let me run behind the Cushite." But Joab replied, "My son, why do you want to go? You don't have any news that will bring you a reward."
He said, "Come what may, I want to run." So Joab said, "Run!" Then Ahimaaz ran by way of the plain and outran the Cushite.
