2 Samuel 18:22

Then said Ahimaaz the son of Zadok yet again to Joab ,.... He could not be easy, even though a messenger was dispatched, but pressed Joab still:

but howsoever, let me, I pray thee, also run after Cushi ; only permit me to go after him, though not as a messenger:

and Joab said, wherefore wilt thou run, my son ? having a great affection for him, and concerned that he should take trouble on him to no purpose:

seeing thou hast no tidings ready ; no news to carry, but what Cushi is gone with, and so can have no audience of the king, nor any reward from him.
