2 Samuel 18:17-18

17They took Absalom's dead body and they threw it into a deep hole in the forest. They made a big heap of stones over the body. All the Israelite soldiers ran back to their homes.

18While Absalom was alive, he had built a tall pillar in the King's Valley. He built it so that people would remember him. He thought, ‘I have no son, so my family's name will not continue.’ He put his own name on the pillar, so people still call it Absalom's Pillar.
