2 Samuel 18:21-22

21Then said Joab to Cushi, Go tell the king what thou hast seen. And Cushi bowed himself to Joab, and ran. 22Then said Ahimaaz the son of Zadok yet again to Joab, But however, let me also, I pray thee, run after Cushi. And Joab said, Why wilt thou run, my son, seeing that thou hast no tidings ready?12
