תנ״ך אויף שמואל ב 8:3

Shmuel rose early in the morning to meet Shaul. It had been told to Shmuel, saying, "Shaul came to the Carmel and is setting up a place for himself. He turned and descended to Gilgal.

And David smote Hadadezer the king of Tzovah in Chamath, when he [(Hadadezer)] went to extend his border to the Euphrates River.

Avsholom had taken and built for himself a monument during his lifetime, which is in the king's valley because he said, "I have no son, this will memorialize my name." He named the monument after himself calling it, "the place of Avsholom." [It remains] until today.
