2 Samuel 18:22-24

Amplified Bible

²² Then Ahimaaz the son of Zadok said again to Joab, “But whatever happens, please let me also run after the Cushite.” Joab said, “Why should you run, my son, seeing you will have no messenger’s reward for going [because you have only bad news]?” ²³ “But whatever happens, Let me run.” So Joab said to him, “Run.” Then Ahimaaz ran by the way of the plain [of the Jordan River] and outran the Cushite.

²⁴ Now David was sitting between the two gates; and the lookout went up to the roof of the gate by the wall, and when he raised his eyes and looked, he saw a man running alone.
