2 Samuel 18:21

18 Now Absalom in his lifetime had taken and reared up for himself a monument, which is in the king's dale; for he said, I have no son to keep my name in remembrance; and he called the monument after his own name; and it is called unto this day, Absalom's memorial.

19 And Ahimaaz the son of Zadok said, Let me run, I pray, and carry the king the news that Jehovah has avenged him of his enemies.

20 And Joab said to him, Thou shalt not be a bearer of news to-day, but thou shalt carry the news another day; but to-day thou shalt carry no news, because the king's son is dead.

21 Then said Joab to the Cushite, Go, tell the king what thou hast seen. And the Cushite bowed himself to Joab, and ran.

22 And Ahimaaz the son of Zadok said yet again to Joab, Come what may, let me, I pray thee, also run after the Cushite. And Joab said, Why wilt thou run, my son, seeing that there is no news suited [to thee]?

23 — But, come what may, let me run. And he said to him, Run. And Ahimaaz ran by the way of the plain, and outstripped the Cushite.

24 And David sat between the two gates; and the watchman went up to the roof of the gate, on to the wall, and lifted up his eyes and looked, and behold, a man running alone.
