2 Kings 23:8-12

Then Josiah brought all the [idolatrous] priests from the cities of Judah, and desecrated the high places where the priests had burned incense [to idols], from Geba to Beersheba, [that is, north to south]; and he tore down the high places of the gates which were at the entrance of the gate of Joshua the governor of the city, which were on one’s left at the city gate.

However, the priests of the high places were not allowed to go up to the altar of the Lord in Jerusalem [to serve], but they ate unleavened bread among their brothers.

Josiah also defiled Topheth, which is in the Valley of Ben-hinnom (son of Hinnom), so that no man could make his son or his daughter pass through the fire [as a burnt offering] for Molech.

And he got rid of the horses that the kings of Judah had given [in worship] to the sun at the entrance of the house of the Lord, by the chamber of Nathan-melech the official, which was in the annex; and he burned the chariots of the sun.

The altars [dedicated to the starry host of heaven] which were on the roof, the upper chamber of Ahaz, which the kings of Judah had made, and the altars which Manasseh had made in the two courtyards of the house of the Lord, the king tore down; and he smashed them there and threw their dust into the Brook Kidron.
