2 Kings 23:8-12

Then Josiah brought all the priests from the cities of Judah, and he defiled the high places from Geba to Beer-sheba, where the priests had burned incense. He tore down the high places of the city gates at the entrance of the gate of Joshua the governor of the city (on the left at the city gate).

The priests of the high places, however, did not come up to the altar of the Lord in Jerusalem; instead, they ate unleavened bread with their fellow priests.

He defiled Topheth, which is in Ben Hinnom Valley, so that no one could sacrifice his son or daughter in the fire to Molech.

He did away with the horses that the kings of Judah had dedicated to the sun. They had been at the entrance of the Lord’s temple in the precincts by the chamber of Nathan-melech, the eunuch. He also burned the chariots of the sun.

The king tore down the altars that the kings of Judah had made on the roof of Ahaz’s upper chamber. He also tore down the altars that Manasseh had made in the two courtyards of the Lord’s temple. Then he smashed them there and threw their dust into the Kidron Valley.
