2 Samuel 18:21-22

21Then Joab said to the Cushite, “Go, tell the king what you have seen.” So the Cushite bowed himself to Joab and ran.

22And Ahimaaz the son of Zadok said again to Joab, “But whatever happens, please let me also run after the Cushite.” So Joab said, “Why will you run, my son, since you have no news ready?”
