2 Samuel 18:17-18

17They 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.

18During 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.
