2 Samuel 18:19

15 And ten young men who carried Joab’s armor surrounded Absalom, struck him, and killed him.

16 Then Joab blew the ram’s horn, and the troops broke off their pursuit of Israel because Joab had restrained them.

17 They took Absalom, cast him into a large pit in the forest, and piled a huge mound of stones over him. Meanwhile, all the Israelites fled, each to his home.

18 During his lifetime, Absalom had set up for himself a pillar in the King’s Valley, for he had said, “I have no son to preserve the memory of my name.” So he gave the pillar his name, and to this day it is called Absalom’s Monument.

19 Then Ahimaaz son of Zadok said, “Please let me run and tell the king the good news that the LORD has avenged him of his enemies.”

20 But Joab replied, “You are not the man to take good news today. You may do it another day, but you must not do so today, because the king’s son is dead.”

21 So Joab said to a Cushite, “Go, tell the king what you have seen.” The Cushite bowed to Joab and took off running.

22 Ahimaaz son of Zadok, however, persisted and said to Joab, “Regardless of whatever may happen, please let me also run behind the Cushite!” “My son,” Joab replied, “why do you want to run, since you will not receive a reward?”

23 “No matter what, I want to run!” he replied. “Then run!” Joab told him. So Ahimaaz ran by way of the plain and outran the Cushite.
