2 Samuel 18:22-23

But 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.” “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.
