2 Kings 23:12-16

He demolished the altars that the kings of Judah had set up on the roof near the upper chamber of Ahaz, and the altars Manasseh had placed in the two courtyards of the Lord's Temple. The king smashed them to pieces and scattered them in the Kidron Valley.

The king also defiled the high places to the east of Jerusalem, to the south of the Mount of Corruption, the places which King Solomon of Israel had built for Ashtoreth, the vile goddess of the Sidonians, for Chemosh, the vile god of the Moabites, and for Molech, the vile god of the Ammonites.

He smashed the sacred stone pillars to pieces, chopped down the Asherah poles, and covered the places with human bones.

He also demolished the altar at Bethel, the high place set up by Jeroboam, son of Nebat, who had made Israel sin. Then he burned the high place, ground it to dust, and burned the Asherah pole.

As Josiah looked around he saw some tombs there on the hill. He had the bones taken from the tombs, and he burned them on the altar to defile it, just as the Lord had said through the man of God who had prophesied these things.
