2 Samuel 18:17-21

And they took Absalom and threw him into a deep pit in the forest, and erected over him a very large pile of stones. And all Israel fled, each to his own tent.

Now Absalom in his lifetime had taken and set up for himself a memorial stone, which is in the King’s Valley, for he said, “I have no son to continue my name.” So he named the memorial stone after his own name, and it is called Absalom’s Monument to this day. David Is Grief-stricken

Then Ahimaaz the son of Zadok said, “Please let me run and bring the king news that the Lord has freed him from the hand of his enemies!”

But Joab said to him, “You are not the man to bring news this day, but you shall bring news another day; however, you shall bring no news this day, because the king’s son is dead.”

Then Joab said to the Cushite, “Go, tell the king what you have seen.” So the Cushite bowed to Joab and ran.
