2 Samuel 18:21-22

21Then Joab said to a man from Sudan, “Go, tell the king what you saw.” The messenger bowed down with his face touching the ground in front of Joab and then ran off.

22Ahimaaz, Zadok’s son, spoke to Joab again, “Whatever may happen, I also want to run after the Sudanese messenger.” “Now, son, why should you deliver the message?” Joab asked. “You won’t be rewarded for this news.”
