2 Kings 23:14-16

14And he brake in pieces the pillars, and cut down the Asherim, and filled their places with the bones of men.

15Moreover the altar that was at Beth-el, and the high place which Jeroboam the son of Nebat, who made Israel to sin, had made, even that altar and the high place he brake down; and he burned the high place and beat it to dust, and burned the Asherah. 16And as Josiah turned himself, he spied the sepulchres that were there in the mount; and he sent, and took the bones out of the sepulchres, and burned them upon the altar, and defiled it, according to the word of Jehovah which the man of God proclaimed, who proclaimed these things.
