2 Samuel 18:18-20

18Now Absalom in his lifetime had taken and set up for himself a memorial pillar which is in the King’s Valley, for he said, “I have no son to keep my name in remembrance.” He named the memorial pillar after himself, and to this day it is called Absalom’s Monument.

19Then Ahimaaz the son of Zadok, said, “Let me run and bring the king news that the Lord has vindicated him by rescuing him from [the power of] his enemies.”

20But Joab told him, “You are not the man to carry news [to King David] today, but you shall carry news another day. On this day you shall carry no news, because the king’s son is dead.”
