2 Samuel 18:19-23

19Then Zadok’s son Ahimaaz said, “Let me run to the king with the good news that the Lord has rescued him from his enemies.”

20“No,” Joab told him, “it wouldn’t be good news to the king that his son is dead. You can be my messenger another time, but not today.”

21Then Joab said to a man from Ethiopia, “Go tell the king what you have seen.” The man bowed and ran off.

22But Ahimaaz continued to plead with Joab, “Whatever happens, please let me go, too.” “Why should you go, my son?” Joab replied. “There will be no reward for your news.”

23“Yes, but let me go anyway,” he begged. Joab finally said, “All right, go ahead.” So Ahimaaz took the less demanding route by way of the plain and ran to Mahanaim ahead of the Ethiopian.
